20100139926 | SYSTEM AND METHOD FOR PERFORMING INTERVENTION OPERATIONS WITH A COMPLIANT GUIDE - A technique for subsea intervention operations incorporates use of a compliant guide that extends between a surface location and a subsea installation. The technique facilitates deployment of tool strings into a subsea well. For example, a portion of the compliant guide can be used as a subsea lubricator during pressure deployment of tool strings. In some applications, a tool entry guide can be connected into the subsea installation to facilitate deployment of tool strings into the subsea well. | 06-10-2010 |
20100163243 | INTERVENTION SYSTEM DYNAMIC SEAL AND COMPLIANT GUIDE - A technique for subsea intervention operations utilizes a retrievable dynamic seal assembly. The retrievable dynamic seal assembly is deployed toward a seabed and locked into place within a tubular member at a subsea installation. During deployment, the dynamic seal assembly is releasably locked to an intervention tool string coupled to a conveyance. Once the dynamic seal assembly is locked in place within the tubular, the tool string is released and the dynamic seal assembly maintains a seal against the conveyance during an intervention operation. | 07-01-2010 |
20100236786 | SYSTEM AND METHOD FOR PERFORMING INTERVENTION OPERATIONS WITH A SUBSEA Y-TOOL - A technique utilizes a Y-tool ( | 09-23-2010 |
20100294505 | SYSTEM AND METHOD FOR FORMING CONNECTIONS WITH A COMPLIANT GUIDE - A technique enables formation of connections between subsea well installations and compliant guides. The technique comprises deploying a compliant guide ( | 11-25-2010 |
20100314122 | METHOD AND SYSTEM FOR SUBSEA INTERVENTION USING A DYNAMIC SEAL - A system for performing intervention operations in subsea installations, including a tubular which connects a subsea installation to a surface vessel, a conveyance designed to enter subsea installation to perform an intervention, and a non-retrievable subsea dynamic seal, which prevents hydrocarbons from reaching the vessel. A surface dynamic seal can be provided. A method for subsea intervention using the system and a corresponding subsea dynamic seal apparatus are provided. | 12-16-2010 |
20120037374 | PLUG REMOVAL AND SETTING SYSTEM - A method for removing a plug from and setting a plug into a subsea installation is provided. The method for removing the plug includes the steps of deploying an intervention package having at least one valve, pipe rams, and a lubricator into a subsea environment and latching the intervention package to the subsea installation. The method further includes lowering a stroking tool into the intervention package by conveyance from a surface facility, and grabbing the stroking tool with the pipe rams that form a part of the intervention package. Once the stroking tool is held by the pipe rams, the method further includes activating the stroking tool to stroke in an upwards or downwards direction to remove the plug positioned in the subsea installation. Once the plug has been removed by the stroking tool, the method further includes pulling the stroking tool out of the intervention package and retrieving the stroking tool and plug at surface. | 02-16-2012 |

20090145610 | Methods of Using Enhanced Wellbore Electrical Cables - An embodiment of a method of deploying a cable into a wellbore penetrating a subterranean formation comprises providing a cable, wherein the cable comprises at least one insulated conductor, at least one armor wire layer surrounding the insulated conductor, a polymeric material disposed in interstitial spaces formed between armor wires forming the at least one armor wire layer, and interstitial spaces formed between the at least one armor wire layer and insulated conductor, the polymeric material forming a continuously bonded layer which separates and encapsulates the armor wires forming the at least one armor wire layer, and whereby the polymeric material is extended to form a smooth polymeric jacket around the at least one armor wire layer, introducing the cable into a wellbore and performing at least one operation in the wellbore utilizing the cable. | 06-11-2009 |
20100116506 | SUBSEA DEPLOYMENT OF SUBMERSIBLE PUMP - A technique for subsea operations utilizes a surface vessel to perform the installation and retrieval of submersible pumps or other tools with respect to a subsea well. A submersible pump is conveyed from a surface vessel to a subsea installation which is used to temporarily secure the submersible pump. Subsequently, the surface vessel is again used in cooperation with a conveyance to deliver the submersible pump to a desired location in a wellbore beneath the subsea installation. | 05-13-2010 |
20130292126 | Methods Of Using Enhanced Wellbore Electrical Cables - An embodiment of a method of deploying a cable into a wellbore penetrating a subterranean formation comprises providing a cable, wherein the cable comprises at least one insulated conductor, at least one armor wire layer surrounding the insulated conductor, a polymeric material disposed in interstitial spaces formed between armor wires forming the at least one armor wire layer, and interstitial spaces formed between the at least one armor wire layer and insulated conductor, the polymeric material forming a continuously bonded layer which separates and encapsulates the armor wires forming the at least one armor wire layer, and whereby the polymeric material is extended to form a smooth polymeric jacket around the at least one armor wire layer, introducing the cable into a wellbore and performing at least one operation in the wellbore utilizing the cable. | 11-07-2013 |
20140352952 | Methods of Using Enhanced Wellbore Electrical Cables - A method of deploying a cable into a wellbore penetrating a subterranean formation that includes providing a cable. The cable includes an insulated conductor; an armor wire layer surrounding the insulated conductor; and a polymeric material disposed in interstitial spaces formed between armor wires forming the armor wire layer, and in interstitial spaces formed between the at least one armor wire layer and the at least one insulated conductor. The method also includes introducing the cable into a wellbore and performing at least one operation in the wellbore utilizing the cable. | 12-04-2014 |
