Definitions

  • This invention relates to an apparatus and a method for deployment of a well intervention tool string into a sub- sea well associated with the production of hydrocarbons.
  • Well maintenance and service comprises a range of methods for deploying relevant tool strings into live wells in order to do work.
  • Traditional methods for deploying/inter- vening relevant tools into live wells comprise wireline, coil tubing, and snubbing.
  • the downhole tools that can be intervened and applied using such methods include perforation guns, zone isolation devices, data recording tools, fluid samplers, a range of mechanical tools and other devices .
  • Maintenance from a platform involves rigging up the required equipment (for instance wireline or coil tubing) on an appropriate deck space. Hence, the costs of maintenance are limited to renting/acquiring the equipment that is directly related to the operation of interest.
  • a lubricator system For intervention or maintenance operations to be performed on a live well, lubricator systems are utilised in order to get tools in and out of the well in a controlled manner.
  • a lubricator system comprises the following:
  • a tree connector This is the interface between the wellhead and the lubricator stack.
  • Valve housings so-called BOP 's (blow out preventers) .
  • BOP blow out preventers
  • These include (gate-shaped) valves, that can cut cable and coil tubing and thereupon form a seal against the live well, as well as valves that can close around the cable/coil tubing, without damaging this, and form a seal against the well pressure.
  • Riser sections This is simply spacer pipe. The accumulated length of the riser and BOP determines the length of tool string that can be intervened into the well in one.run.
  • Top seal assembly In order to run a cable or a coil tubing in and out of a well environment, a system that seals between the high-pressurised well environment and the atmospheric (for surface operations) or seabed pressure (for subsea operations) conditions on the outside of the lubricator, is needed.
  • stripper rubbers that are ring-shaped moulds of an elastomer material, nylon, Teflon or similar are used. Stripper rubbers are commonly split in two for mounting purposes and access during the operation.
  • Annular bags can also be utilised for coil tubing operations. These are ring-shaped, elastomer-based barrier systems . Rubber elements are inflated around the coil in order to create a seal against it.
  • Annular bags are also commonly used for heavier pipe operations, such as drilling. A major difference between the stripper rubber and the annular bag is the latter 's ability to seal against objects/pipe of various diameter.
  • stuffing boxes which is a stack of elastomer packers that seal around the wire.
  • GSH grease injection head
  • a lubricator ensures that barrier requirements are complied with during all stages of the well intervention operation. This means that new barriers (between the high- pressurised well fluid and the open environment) are established before old barriers are removed.
  • a typical well intervention operation involves the following steps:
  • a subsea lubricator system common of today, is simply a "marinated" surface lubricator system, by means of adding features that compensate for the fact that there is a marine environment on the outside of the lubricator rather that atmospheric air.
  • in- creaseing height means increasing bending momentum at the base of the subsea stack where the lubricator is anchored to the subsea wellhead.
  • the latter has been a significant challenge and limitation with today's lubricators.
  • the lubricator become too high, big and bulky, this would impose additional requirements to the vessel, which again could make the operation exceed accepted economical limits .
  • the length of tool string that can be intervened in one run is limited to approximately 20 metres.
  • lubricator concepts that apply telescopic joints in order to lengthen the lubricator.
  • telescopic joints are elongated downwards through the open wellhead, hence a lengthening of lubricator space by a factor close to 100%, compared to standard subsea lubricator systems, can be achieved.
  • DHSV downhole safety valve
  • DHSV closed down hole safety valve
  • the tools are brought into the well through a "wide open wellhead” .
  • the top seal assembly for example a grease injection head
  • the DHSV is opened and the tools are run to the lower sections of the well to do the work.
  • the lubricator stack and its functions are not removed, but the riser section is, and thereby the main component that contributes to height.
  • the invention has as its object to remedy, or at least reduce, one or more drawbacks of the prior art.
  • a further object of the present invention is to provide a method for utilising the apparatus according to the invention.
  • the invention aims at reducing lubricator height and, at the same time, dramatically increasing the length of tool string that can be intervened in one operational step.
  • the invention comprises a subsea deployment system and a method for conducting intervention.
  • the subsea deployment system comprises two main modules, a first module that attaches to the subsea wellhead and/or lubricator assembly, and a second module that attaches to the tool string to be intervened.
  • the first module of the invention comprises a subsea deployment lubricator module hereinafter denoted as "SDLM”, which is a system component, or stack of system components, that forms part of a subsea lubricator.
  • SDLM subsea deployment lubricator module
  • the second module of the invention comprises a subsea deployment intervention module hereinafter denoted as "SDIM" which attaches to the tool string to be intervened.
  • SDLM subsea deployment lubricator module
  • SDIM subsea deployment intervention module
  • the SDLM is the "lubricator part" of the subsea deployment system.
  • the lower end of the SDLM is attached to the wellhead and the upper end attached to a BOP (Blow Out Preventer) module.
  • the lower end of the SDLM is attached to the wellhead indirectly, by means of an interface module, a LRP (Lower Riser Package) or other similar equipment .
  • the SDLM comprises a main bore, preferably provided in the centre region, and normally of similar or larger inner diameter than the wellbore itself.
  • the SDLM comprises a seal arrangement.
  • the seal is a dynamic seal.
  • this is a stripper rubber made of elastomer, nylon, Teflon or similar material.
  • the seal arrangement is forced radial inwards to seal around any matching object that is inserted in the bore of the SDLM.
  • the seal arrangement is an annular bag or similar system that inflates around objects in the centre of the SDLM.
  • the seal arrangement comprises one of said two sealing elements. In another embodiment of the invention, the seal arrangement comprises a stack of multiple amounts and/or types of sealing elements. In one embodiment of the invention, some of the seals in a stack serve the purpose as a well barrier, whereas other serves the purpose as "vipers" in order to prevent pollution to the sea. In one embodiment of the invention, only the "vipers" are fully active during normal operation, whereas the other sealing arrangements are activated in the case of emergency.
  • the SDLM also comprises a valve assembly. This serves the purpose to prevent upward segregating fluids from the well to pollute the marine environment in parts of the operational sequence. Also, the valve assembly serves the purpose of providing a barrier against the well during certain operational stages, and to provide means for pressure testing against, in order to verify seal integrity.
  • the valve assembly includes a double set of flapper type valves, where the upper is a tri-arm flapper and the lower is a conventional flapper valve.
  • the upper tri-arm flapper valve opens by means of forcing the intervention string assembly into it whereupon the lower flapper automatically opens as the two valves are mechanically hinged.
  • the lower valve may be able to contain elastomer seals, sealing surfaces and other features that should not be exposed to mechanical contact with the intervention string.
  • the upper tri-arm flapper is to be considered a mechanical activation mechanism for the lower flapper that is the real barrier/sealing mechanism towards the wellbore.
  • the valve/ valve assembly is spring-loaded and biases towards a closed position. In this case, should the intervention string be retrieved out of the valve assembly, the valves will automatically close.
  • valves are complemented with another valve, typically a ball- or a gate valve, located below the other valves.
  • This valve enables pressure testing of seal integrity at the time of stinging the tool string assembly into the SDLM.
  • this latter valve fully replaces the need for one or both of the described flapper valves and is the only valve that is required for the described purposes .
  • the valve assembly includes or comprises alternative valve types, such as ball valves, gate valves and other valves as well as a combination of such type valves.
  • valves could be op- erated mechanically, electrically, hydraulically or by means of other relevant forces, using intervention tools or surface operated electrical, hydraulic or other surface operation mechanisms connected to the subsea mounted equipment.
  • wireless activation signals could be applied to activate the valves.
  • the SDLM comprises an anti-blowout system.
  • this is a device that is pre-installed and is centered in the bore of the SDLM, an anti-blowout sub, which attaches to the intervention string assembly during deployment.
  • the anti-blowout sub has an OD that is larger than the ID of the SDLM above the hang-off point of the anti-blowout sub. Hence, the intervention string can not be blown out of the well .
  • the anti-blowout sub and the matching anti-blowout profile in the SDLM have the shape and characteristics of a dampener.
  • the two components form the male and female of a hydraulic dampener, where fluid becomes trapped between the anti-blowout sub and the anti-blowout profile of the SDLM, and the said fluid only can escape via narrow channels that reduce in size or number the more fluid that is displaced. Hence, a gradual dampening pattern is achieved in order to avoid system damage due to hard impacts between the anti-blow-out sub and the SDLM.
  • the dampener mechanism is based on other known dampener principles such as springs, friction dampeners and other.
  • the anti-blowout function is handled by means of a gripping/locking system that prevents upward movement of the intervention string assembly.
  • upward movement of the intervention string assembly directly mechanically activates the gripping/locking system.
  • the gripping/locking system is activated by means of sensors detecting unwanted situations (leakage, kick, blowout, unexpected upward movement of the intervention string assembly) .
  • sensors could include detection devices for motion, position, pressure, fluid flowrate, fluid composition, volumetric changes and other.
  • the gripping/locking system is operator activated.
  • the gripping/locking system comprises a combination of some or all of the herein mentioned activation features.
  • the gripping/locking system includes slips that slide gently along the intervention string assembly while this is being deployed into the well, but makes a firm grip at the instant this starts to move upwards.
  • the slips are foreseen retrieved/removed radial to some distance away from the intervention string assembly in order to deploy this out of the well (i.e. upward movement), but linked, in a fail-safe mode, to a release mechanism that activate the slips and make them grip the intervention string assembly in case an un-wanted event (e.g. a blowout, a kick or similar) should take place.
  • an unwanted event could be indicated by means of monitoring the speed of the upward movement of the intervention string assembly, the fluid displacement into the well during deployment out, acceleration or other indicators of unwanted events, or a combination of such.
  • the gripping/locking feature is ensured by means of operator activation of the annular bag that in one embodiment forms part of the seal arrangement of the SDLM.
  • the annular bag is not fully inflated against the intervention string assembly during normal operations, but only so in the case of an emergency.
  • the SDLM comprises flushing systems in order to remove unwanted fluids from contained spaces before opening access to the well, to the open environment, to flowlines or similar.
  • flushing lines are run and operated from the vessel used for the subsea intervention operation.
  • dedi- cated vessels/tanks and pump systems are used for flushing purposes .
  • the SDLM and accessories comprises design and system to avoid fluids being trapped in contained spaces, which can prevent system functionality.
  • the SDLM and accessories comprises means for pressure testing and monitoring of such during all relevant operational stages.
  • the SDLM and accessories comprises means for monitoring of operational parameters such as pressure, temperature, fluid flow rate, volume displacement and fluid properties during all stages of the operation.
  • the SDLM comprise a position indicator system that corresponds with the intervention string assembly.
  • the SDLM comprises a stop arrangement for preventing further insertion of the intervention string assembly into the SDLM. Also, the SDLM comprises means for locking parts of the intervention string assembly in place during certain operational stages.
  • the SDLM comprises access for a kill line to be attached, should there occur a need to kill the well.
  • the kill line is run and operated from the vessel used for the subsea intervention operation.
  • the whole or parts of the SDLM is incorporated as a part of a permanent subsea wellhead system.
  • the valve assemblies could form part of such a permanent system.
  • the SDIM is a device that, together with the intervention tools themselves, forms an intervention string assembly of the subsea deployment system.
  • the SDIM comprises a tubular element, hereinafter denoted as "flush pipe” and inner seal/latch subs to be mounted on the intervention tool string of interest.
  • the tool string is mounted inside the flush pipe with at least one seal/latch sub provided in each endportion of the intervention tool string.
  • the outer surface of the flush pipe is uniform and smooth and forms a seal against the SDLM' s seal arrangement.
  • this forms a seal in the annular space between the well and the open environment.
  • another seal of similar purpose is provided on the inside of the flush pipe present in the annular space defined by the flush pipe and the seal/latch subs attached to the tool string.
  • the connector mechanism comprises a standard latch system, such as a GS type latch.
  • the anti-blowout sub latches onto the flush pipe of the SDIM (and not the tool string) .
  • the anti-blowout sub is hollow and allows the intervention tool string to be run through it.
  • At least one of the seal/ latch subs comprises a latch that attaches the intervention string to the flush pipe.
  • the flush pipe does not cover parts of the tool string during installation. Typically, this involves cases where the tool string can be made of similar uniform shape and outer diameter as the flush pipe, and/or cases where said non-covered parts of the tool string are going to be permanently left in the well, such as for zone isolation devices.
  • the flush pipe is omitted. This would typically apply for cases where the entire tool string can be made of similar uniform shape and outer diameter as the flush pipe.
  • the flush pipe includes a so-called "no-go profile" in the top portion that matches a similar profile in the SDLM. This feature physically prevents the flush tube from being deployed lower than the no-go profile permits.
  • the no-go feature is a very important system feature in case of an emergency. Should there occur a need to drop the SDIM, this will stop in a controlled manner in the no- go profile. Otherwise, a falling SDIM could drop through the downhole safety valve and create a severe situation.
  • the no-go system includes one or more dampening functions to enable a smooth landing of the SDIM into the SDLM, said functions could be hydraulic-, spring-, friction-based or other damper principles .
  • seal/latch subs In some situations, for example in the case of tool strings of varying outer diameter and shape, like production logging strings, it might not be feasible to use solid, large size seal/latch subs. In particular, such seal/latch subs could conflict with the operational scope if placed in the bottom of such tool strings.
  • hollow, fluted, expandable or similar feature seal/latch subs are used.
  • the bottom and/or other parts of the flush pipe is provided with a valve system. This could comprise one or more ball valves, gate valves, flapper valves, or other types and/or combination of valves.
  • valve system could be by means of a shifting tool located in the bottom of the tool string, or by means of surface operator controls that are mechanical, hydraulic, electrical, fibre-optical and/or wireless activation based.
  • Remote activation techniques such as wireless signals based on acoustic, electromagnetic, pressure pulse or other methods known per se, could be applied to activate the valve system.
  • the SDIM comprises a system for fluid displacement.
  • this feature could be applied in cases where it is not possible to obtain a good seal between the flush pipe and the seal/ latch subs after the tool string has been in the well.
  • the SDIM comprises passive modules of a position indicator system. This could be magnets, weak radioactive sources and other types of passive system components known per se. In another embodiment of the invention, the SDIM comprises active position indicator modules.
  • the bottom section of the flush pipe is compatible with plugs, by means of having necessary reinforcements and/or plug setting profiles.
  • the sub- sea well of interest will produce into a manifold that receives flow from a number of wells.
  • the manifold will be pressurised during the entire subsea intervention operation. This prohibits displaced fluids from the deployment operation to be routed into the manifold.
  • the downhole safety valve typically a flapper valve
  • the downhole safety valve will be closed and have a significant pressure under it, hence displaced fluids can not be routed into the well neither.
  • VMSM volume monitoring and storage module
  • the VMSM comprises components for monitoring in- and out-flux of fluids from the well as well as other relevant data when deploying in and out of the well.
  • the instrumentation of the VMSM includes sensors for measuring pressure, temperature, flow rate, fluid composition, volumetric changes, density and other relevant parameters in order to gain sufficient control of what fluids goes in and out of the well during the various operational steps.
  • the VMSM also comprises a system for handling and/or storing fluids that are displaced and replaced during the operational sequences.
  • the VMSM comprises a tank, located at the seabed or at the vessel itself, that fluids are routed to while deploying into the well and returned from when deploying out of the well.
  • the VMSM comprises a pump system that enables displacement of fluids to the production header while deploying in, and retrieval of fluids, from the same header or an alternative location, when deploying out of the well.
  • a line from a dedicated tank at the seabed or the surface vessel supplies a hydrate inhibitor that is routed into the wellbore when deploying out of the well. In that way, excessive handling of wellbore fluids is avoided.
  • access to the wellbore fluid is achieved by mounting the VMSM onto the choke bridge of a subsea wellhead.
  • the same access is achieved by means of dedicated ports in the SDLM or an alternative location on the subsea stack and/or flowline system.
  • the subsea deployment system according to the present invention will typically be applied for all subsea well intervention operations.
  • the subsea deployment system could be a valuable system component in each and every subsea intervention operation.
  • the subsea deployment system enables operations, that otherwise would require several runs in the hole, to be performed in only one run.
  • operations typically involve deploying long perforation guns, zonal isolation strings or data logging strings.
  • a typical subsea deployment and intervention method according to the invention would include the following steps:
  • a pressure test is conducted to confirm seal integrity across the dynamic seal of the SDLM. For horizontal x-mas trees, this pressure test is conducted against a valve in the SDLM valve assembly. For vertical x-mas trees, this pressure test could be conducted against one of the valves in the tree itself.
  • the anti-blowout sub is released from the SDLM and the SDIM is continued lowered into the hole.
  • the SDLM valve assembly is opened and the SDIM is lowered further, until the top of the SDIM is inside the SDLM and the no-go profiles meet.
  • the SDIM is anchored to the SDLM top section.
  • the tool string is released from the flush pipe. This can be achieved by means of applying forces to the wireline cable or coil tubing, or by means of applying hydraulic, electrical, mechanical or other forces and/or impulses to the flush pipe through the wireline, coil tubing or directly from the vessel to the SDLM itself. Also, wireless communication methods could be applied for this purpose.
  • the tool string is run to the well section of interest, whereupon it performs the relevant operation, before it is retrieved out of the well .
  • the tool string is pulled into the flush pipe and latches onto the flush pipe's seal/latch sub profiles.
  • the seals in the seal/latch subs in the top and bottom of the tool string ensures that pollutants from the well that might have attached to the tool string are now contained inside the flush pipe while deploying this out of the well and through open water.
