Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a PCT application claiming priority of
U.S. Provisional Patent Application No. 60/926,517 entitled MODULAR
WELL SERVICING UNIT filed 29 Apr. 2007 which is herein incorporated
by reference.
BACKGROUND
[0002] The invention relates generally to to the treatment of oil
and gas wells using fluids to increase the production capability of
the wells and more particularly to dismounting, mounting,
monitoring, and controlling well servicing modules.
[0003] Well serving units are conventionally configured at the
point of manufacturing, and the well servicing functions that any
particular unit performs are fixed at the point of
manufacturing.
[0004] Conventional units usually only have a single function. A
conventional coil tubing unit provides coil tubing. A conventional
nitrogen unit provides nitrogen. Each unit has its own conveyance,
power source, and control system. For instance a conventional coil
tubing unit has its own truck, power supply to the unit (not the
truck engine) and control console.
[0005] Conventional well servicing units may take 6 to 18 months to
manufacture.
[0006] Combination units such as those described in U.S. Pat. No.
6,702,011 and U.S. Pat. No. 7,051,818 have a non-modular,
monolithic design.
[0007] The approaches described in this section are approaches that
could be pursued, but not necessarily approaches that have been
previously conceived or pursued. Therefore, unless otherwise
indicated, it should not be assumed that any of the approaches
described in this section qualify as prior art merely by virtue of
their inclusion in this section.
BRIEF DESCRIPTION
[0008] The invention provides means for dismounting and mounting
well servicing modules for assembly, maintenance, and modification
of well servicing combination units as well as standardization,
control, and monitoring of said modules.

DETAILED DESCRIPTION
[0018] In the example shown in FIG. 1, after a customer who has a
problem with his well describes the problem to a sales engineer,
the sales engineer determines which modules and functions are
needed to perform the service that the customer requires and
configures a unit to the job specification. The crew in the depot
100 assembles the unit needed from the modules 80, 50, 60, 10 in
the module inventory. Once the Unit is configured and tested, it
leaves the depot 100 to go to the job site. In this example, module
10 is a truck power pack module, module 60 is a Crane Trailer
Module, module 50 is an operator control module or command module,
and module 80 is a coil tubing module.
[0019] FIG. 2 shows the module inventory remaining at the depot 100
after the unit assembled for the first customer has left for the
job site. These inventory modules remain available for deployment
on a new job.
[0020] In the example shown in FIG. 3, a second customer describes
requirements to a sales engineer who determines which modules and
functions are needed to perform the service that the second
customer requires and configures a unit to the job specification.
The crew in the depot 100 assembles a second unit from the modules
in inventory. Once the unit is configured and tested, it leaves the
depot 100 to go to the job site. In this example, module 11 is a
truck power pack module, module 51 is an operator control module or
command module, and module 30 is a wireline module.
[0021] FIG. 4 shows the module inventory remaining at the depot 100
after the two units assembled for the first and second customers
have left for the job site. These inventory modules remain
available for deployment on a new job.
[0022] FIG. 5 shows an example of the work flow for a module swap
out required for an unscheduled repair. In this example, the unit
configured for the first customer, as shown in FIG. 1, has damage
on coil tubing module 80. The unit has returned to the depot 100,
where there is a second coil tubing module 81 waiting in the module
inventory. The working module 81 removably mounted on the unit
after the broken module 80 has been dismounted. By swapping out
modules in accordance with an embodiment of the present invention,
it's possible to keep the unit in service while the module 80 is
being repaired.
[0023] FIG. 6 shows the unit leaving the shop to return to the job
site, while module 80 is moved to the repair facility 101 where a
maintenance crew will repair, test, and re-certify it for return to
module inventory 100.
[0024] FIG. 7 depicts module 80 returned to module inventory at the
depot 100, where it is ready to be removably mounted on a unit.
[0025] Turning now to FIG. 8, module or component managers 90, 91,
92, 93 are in communication with unit manager 94 accordance with an
embodiment of the present invention.
[0026] Unit manager 94 is in communication with onboard computer
and user interface 95 local to unit (in Command Module 50).
[0027] Operator Control Module 50 comprises unit manager 94 and
onboard computer and user interface 95
[0028] Any anomalous events are communicated to centrally located
database 97.
[0029] Well servicing modules 10, 20, 30, 40 can be remotely
monitored at user interface (terminal) 98.
[0030] The satellite 102, or other communications path (such as
long range cellular phone) connect the performance and support
center 97 with the well servicing modular unit.
[0031] When something goes wrong with a module, it is reported to
central immediately, and arrangements to repair/replace module are
made. Entire unit can return to depot or intermediate location or
just module(s) can be transported to achieve repair/replacement
while unit remains working on site.
[0032] Unit can notify the depot to be ready to change a module
out.
[0033] A system in accordance with an embodiment of the present
invention can achieve: [0034] Standard Monitoring and Control
Interfaces for All Site Components, [0035] Wireless Communications,
[0036] RFID Tracking of Assets, [0037] GPS Tracking of Assets,
[0038] Instant Alerts, [0039] Instant Link to Other Components, and
[0040] Video and Audio to Other Personnel.
[0041] A system or apparatus in accordance with an embodiment of
the present invention can provide: [0042] Instant Involvement of
all Required Personnel, [0043] Reduced Outages, [0044] Shorter
Outages, and [0045] Audit Trail of all Events.
[0046] The systems, methods, and apparatus depicted in the figures
are equally applicable for an offshore unit and amphibious
units.
[0047] Analogous to the way the term "plug and play" indicates easy
addition of a new computer device, normally a peripheral, without
requiring reconfiguration or manual installation of device drivers,
"plug and work" is a term meaning easy addition of mechanically and
electrically compatible modules to a unit that provides shared
power and central module management. Because units according to an
embodiment of the present invention are modular, they can be put
together at the depot to have all the functions needed to perform a
specific job. Modules that represent functions not needed on the
specific job are left at the depot. Because the modules are built
to share power and control, each module does not need to contain
its own power source. This saves weight and footprint at the job
site. Interchangeable modules enable "fit-for-purpose" well
servicing units and multiple deployment options for land, offshore,
and in-between (marshes etc.). These modular units deliver multiple
well servicing functions such as coil tubing plus a nitrogen
source, but conventional units only have a single function (such as
a Coil Unit or a Nitrogen Unit only). Modularity takes full
advantage of compact, lightweight modules for unmatched deployment
flexibility of well servicing systems.
[0048] A modular design in accordance with an embodiment of the
present invention enables flexibility of configuration (which
modules are assembled together) and efficiency in maintenance. With
the establishment of standards and procedures, a fleet of modules
and units can be deployed more quickly than monolithic units.
[0049] A system integrator approach in accordance with an
embodiment of the present invention is enabled by modular designs
of the well servicing function modules. Every piece of well
servicing equipment becomes a module to be integrated or assembled
into a working unit. This allows design flexibility without
sacrificing production capacity. It has direct impact on the depot
maintenance programs that keep units working, and reduces the
number of different spare parts in inventory through module
standardization, which also saves cost.
[0050] In accordance with an embodiment of the present invention,
central power and control reduces unit footprint and weight, while
modularity allows customization to meet more stringent weight and
size requirements. The advantage of small foot print allows units
to fit on small barges and boats that conventional units cannot
squeeze onto.
[0051] In accordance with an embodiment of the present invention,
central power and control and modularity allow units that require
less rig up and rig down time, and fewer number of crew.
[0052] In accordance with an embodiment of the present invention,
modularity enables the customization and building of
multifunctional well servicing units to meet specific function
requirements in the field through customized module integration at
the depot for each job.
[0053] In accordance with an embodiment of the present invention,
modularity and standardization affords maximum flexibility in the
selection and relationship with multiple vendors, component
suppliers, module fabricators (commercial off the shelf, or custom
designs), system integrators and assemblers.
[0054] Conventional well servicing units may take 6to 18 months to
manufacture. During this time capital is tied up. In accordance
with an embodiment of the present invention, once a unit is
ordered, modules can be produced on parallel manufacturing lines.
Once all modules are on the assembly yard or system integrator
yard, a supplier can assemble and test a unit comprising specified
modules in an about 30 days. Inventory costs should run for about
45 days rather than for months.
[0055] In accordance with an embodiment of the present invention,
faster build times achieved through parallel manufacturing lines
can be further improved when long-lead-time modules are inventoried
and integrated with other short delivery time modules.
[0056] In accordance with an embodiment of the present invention,
"Plug and Work" standardization means modules are compatible
because compatible hardware interfaces are defined so that they
modules fit together with no additional design work.
[0057] In accordance with an embodiment of the present invention, a
unit can comprise only the modules whose functions are needed for a
particular job and there is no dead weight.
[0058] In accordance with an embodiment of the present invention, a
unit allows higher revenue per unit and higher profit per unit
because of increased "operational availability". Operational
availability is the ratio of days per month a unit is on the yard
available for work, divided by the number of days in the month.
Additional "uptime" with little or no additional fixed cost is
possible because modules can be swapped and replaced anywhere,
provided there are not environmental constraints to reaching the
location of the unit, such as mud etc. Then the broken module can
be fixed and put back in the operations inventory (depot inventory)
to be used as needed as shown in FIGS. 1-7. This keeps a unit in
service making money more days per month, but with no additional
fixed costs such as crew. There is no additional capital cost,
other than module inventory. In accordance with an embodiment of
the present invention, a unit can be kept working by quickly
changing out modules. If a conventional unit has a problem such as
a component breaking down it must return to the depot or shop.
[0059] In accordance with an embodiment of the present invention,
modules can be quickly replaced with a module in inventory at the
depot, or a module in inventory can be transported to the unit for
replacement in the field.
[0060] In accordance with an embodiment of the present invention,
depot modularity means units comprising discrete modules can be
configured with the functions needed to meet a particular job
specification. A unit's modules can be switched out with a forklift
and an overhead gantry at the depot. For example, it's possible to
switch out a coil tubing module from a unit for another coil tubing
module that has just been refurbished.
[0061] In accordance with an embodiment of the present invention,
field modularity means the ability to swap modules anywhere outside
of the depot, certainly wherever a truck and crane trailer can be
driven. The location could be the jobsite or other locations as
well. This enables extensive maintenance and repair to be done in
the field.
[0062] In accordance with an embodiment of the present invention,
module management means keeping track of the module inventory in
the depot, and the status and location of modules in the field,
allowing efficient scheduling for maintenance or changing job
requirements by swapping a module needing repair or maintenance or
new capability out of a unit and replacing it with a module from
the depot inventory.
[0063] In accordance with an embodiment of the present invention, a
unit can be "Fit-For-Purpose", meaning reconfiguring a unit with
different module types that have different functions whenever new
capability is desired for a job. This means the ability to switch
different types of modules in and out of a unit. For example, a
"Combination Coil Tubing and Nitrogen Unit" might need to be
morphed into a "Nitrogen and Pressure pumping unit" by removing the
Coil Tubing Module and replacing it with a Pressure Pumping
Module.
[0064] In accordance with an embodiment of the present invention, a
unit's "Module Maintenance and Repair" means swapping out one
module for a module of the same type: such as nitrogen module for
another nitrogen module.
[0065] In accordance with an embodiment of the present invention, a
module-based well intervention services system using shared power,
control, and job performance information is shared in near real
time with a backend knowledgebase that can be monitored in
real-time. The job knowledgebase can provide information for
applications such accounting, safety, maintenance, etc.
[0066] In accordance with an embodiment of the present invention, a
unit may comprise several modules, using shared systems,
hydraulics, power, monitoring, and control.
[0067] In accordance with an embodiment of the present invention, a
unit may comprise any of the following types of modules and
components:
[0068] Coiled Tubing (reel, injector head, blow out preventor
stack),
[0069] Nitrogen (cryogenic or nitrogen generated onsite from the
atmosphere),
[0070] Pump (fluid, pressure),
[0071] Wireline, and
[0072] Down Hole Tools
[0073] In accordance with an embodiment of the present invention,
possible modules and components are expandable to include other
types of modules and components.
[0074] In accordance with an embodiment of the present invention, a
unit and each module should be standardized, designed,
instrumented, and interfaced with the central performance
architecture and knowledge base for optimized job performance and
maintenance.
[0075] In accordance with an embodiment of the present invention, a
unit can hook up with a power take off to a large engine such as an
onsite engine, a large boat diesel, a turbine, or other external
power, to allow integration of more modules.
[0076] In accordance with an embodiment of the present invention, a
unit can have the ability for the command module to manage one or
more power sources so that power can be provided based on the
combined needs of the modules.
[0077] In accordance with an embodiment of the present invention, a
unit modularity provides flexibility to meet local or niche market
needs and also advantages in supportability and post-commissioning
logistics.
[0078] In accordance with an embodiment of the present invention, a
command module manages modules that provide functions to support
the well intervention job. Modules should be built in compliance
with the plug and work specification.
[0079] In accordance with an embodiment of the present invention, a
unit should preferably have a standardized closed circuit hydraulic
shared power system rather than a open circuit system, because a
closed circuit system should have more useable horsepower).
[0080] In accordance with an embodiment of the present invention,
one or more of the following in any combination where the
interfaces are so defined so that the modules will "plug and work"
together: [0081] Data Acquisition and Monitoring System as defined
by the command module to support the modules, functions, and points
needed. [0082] Command Module--Operator control Module with control
panel (hydraulic controls becoming increasingly mostly electronic
or electromechanical; adding computer systems, displays, controls,
applications, touch screens, communications, audio, video, etc.),
[0083] Coiled Tubing Deployment module that can include an Injector
head, Blow out preventor, well control stack, Reel, and tubing,
[0084] Nitrogen Module: (cryogenic nitrogen or nitrogen generated
onsite from the atmosphere), [0085] Blow Out Preventor/well control
stack, [0086] Injector head, [0087] High Pressure Pumping, [0088]
Mixing Tanks, [0089] Fuel Tank, [0090] Crane, [0091] Power source
(tractor with wet-kit or power pack), [0092] Trailer, [0093] Mobile
Marine Power Pack, [0094] Fluid pump module, [0095] Offshore
transport skids, [0096] Hose reel skid, [0097] Hydraulic work over
module [0098] Crane trailer, and [0099] Wireline Module (can
include downhole tools).
[0100] In accordance with an embodiment of the present invention,
when a new module is plugged in the command module recognizes it
immediately. The command module sees the new module the way a
computer sees a new plug and play peripheral. Operator control
module and command module queries the new plugged in module and
asks it who it is. The module responds with a serial number or
other identification and, command module manager looks that serial
number up in a look-up table from a database. The command module
will have a communications manager that will be protocol
transparent so the command module can always sync up to the central
performance and support center. The command module can inform the
Depot automatically when a module has broken and ask for a new
module to be brought out.
[0101] In accordance with an embodiment of the present invention,
global positioning system chips can be placed on modules and used
to track the modules.
[0102] In accordance with an embodiment of the present invention,
monitor capabilities of a command module can reach any point on any
module so that if desired, module sensors could be used to create
measurements, monitor, log, and send data to and from the central
knowledge base. A remote user could be able to see virtually
anything because of the greatly expanded ability to monitor any
point on a unit that can be integrated with sensors, alarms, video,
and so on.
[0103] In accordance with an embodiment of the present invention,
power should preferably be hydraulically transferred, to save space
and weight. Available horsepower from a single engine is converted
to hydraulic pressure and is allocated as needed by a command
module.
[0104] In accordance with an embodiment of the present invention,
all well intervention servicing operations--such as, coiled tubing,
nitrogen, and fluid pumping--are preferably monitored and
controlled by one trained specialist at a console in the operator's
cabin. Centralized, single-point control eliminates communications
and coordination problems--such as yelling above equipment noise,
having to use hand signals or a headset--and enables almost instant
response to changing well conditions.
[0105] In accordance with an embodiment of the present invention,
modularity provides optimum unit configuration flexibility to meet
local requirements and enables a supplier to easily configure and
re-configure for local or niche markets. Some configurations will
be used more frequently than others, depending on local market
demand. Units can be configured for market niche needs, which may
be geographically determined. A supplier only needs an estimate of
how many modules will be needed, not the exact configurations. This
shortens manufacturing time because with standard interfaces, most
module types can be interchanged for one another, within the limits
of the differences in the required foot print.
[0106] Offshore units can be just as unforgiving to a footprint
constraint and even more inflexible on a weight constraint. Onshore
units are constrained by "over the road" legal restrictions of
municipalities that will be traversed from depot to job site.
[0107] In accordance with an embodiment of the present invention,
only required modules need be sent to the job, for reduced cost of
module inventory and spare parts.
[0108] In accordance with an embodiment of the present invention, a
unit can reach previously unreachable wells such as those in silted
up access channels inaccessible to conventional units--too shallow
water for boats or barges, but too wet for trucks, by using
amphibious vehicles.
[0109] In accordance with an embodiment of the present invention,
standardization of all module external interfaces allows exchange
of one module for another of the same type and will drop right into
the unit configuration.
[0110] To change a module of one type in a unit for a module of
another type changes the unit configuration because different types
of modules comprise the unit. A key factor is the footprints of the
different modules.
[0111] Compared to conventional units, a unit in accordance with an
embodiment of the present invention typically has more payload,
less equipment, smaller footprint, lighter weight, more power at
the required location, less transportation cost, less rig up and
rig down time, more efficiency (less crew required), and more
effectiveness due to better monitoring and control.
[0112] In accordance with an embodiment of the present invention,
it is possible to rebuild each system of each module without
rebuilding all modules at the same time.
[0113] Maintenance rebuilds of modules can be done one-by-one as
part of scheduled maintenance. Meanwhile, the unit can remain in
continuous service. Less costly maintenance can minimize mean time
between failures and the duration of each outage.
[0114] In accordance with an embodiment of the present invention,
compact, lightweight modules are easily handled by cranes.
[0115] Units in accordance with an embodiment of the present
invention allow fast rig-up and rig-down at jobsite and improved
jobsite safety, minimum transportation requirements, simplified
maintenance and repair, faster build times and maximized
operational availability. Because a unit in accordance with an
embodiment of the present invention is lighter, smaller, and
cheaper than conventional units, it can service wells that would
not be practical or economical for conventional units such as
offshore wells with small platforms with limited deck space or
structural strength, marshland wells reachable only by amphibious
vehicles, wells in remote areas, beyond the reach of economical
cyrogenic liquid nitrogen supplies
[0116] In accordance with an embodiment of the present invention a
command module (parameter driven, configurable, flexible)--could be
changed based on the modules. Modules could be changed based on a
plug and work specification and the functions would be therefore
changed to provide the new or different job management using the
performance architecture, shared power and control.
