Patent application number | Description | Published |
20090001304 | System to Retrofit an Artificial Lift System in Wells and Methods of Use - Pump systems for installation in a wellbore and associated methods are disclosed. The pump system includes one or more internal safety valves that may include a closure mechanism, a biasing mechanism, and an actuator. | 01-01-2009 |
20090090501 | REMOTELY CONTROLLABLE WELLBORE VALVE SYSTEM - A remotely operable wellbore valve system includes a valve configured to be coupled to a wellbore conduit and to selectively close the conduit. The valve is disposed in a valve body configured to open an existing wellbore valve by longitudinal motion therethrough and to sealingly engage an interior of the existing wellbore valve. The system includes a valve actuator and a signal receiver in communication with the valve actuator. The signal receiver is configured to detect command signals transmitted from the Earth's surface and to cause the actuator to operate the valve in response to the detected command signals. | 04-09-2009 |
20090145596 | GUIDE TOOL FOR GUIDING DOWNHOLE TOOLS THROUGH WELLBORE RESTRICTIONS - A guide tool for mounting onto a downhole tool for use in a wellbore penetrating subsurface formations is provided. The guide tool has a bull nose. The bull nose has a first section with an end for sealing against and engaging a lower end of the downhole tool and a second section axially deflectably coupled to the first section. | 06-11-2009 |
20090183884 | METHOD FOR SEALING WELLBORE LEAKAGE AND SHUTTING-OFF OF WATER PRODUCING ZONES - A method for sealing a wellbore includes moving a running tool with a sealing material disposed therein into a wellbore proximate a portion of the wellbore to be sealed. A cylinder is moved into the wellbore along with the running tool proximate to the portion to be sealed. The cylinder defines an annular space between an exterior thereof and an interior of the wellbore. The sealing material is deployed into the annular space. The running tool is then removed from the wellbore. | 07-23-2009 |
20090260830 | RIGLESS WELL COMPLETION METHOD - A method and system for completing a well below the bottom of a body of water includes assembling a completion string at a location away from a location of the wellbore, moving the assembled completion string to the location of the wellbore and inserting the assembled completion string into the wellbore. | 10-22-2009 |
20090266537 | COMBINATION INJECTION STRING AND DISTRIBUTED SENSING STRING FOR WELL EVALUATION AND TREATMENT CONTROL - A method for well intervention includes extending a combination conduit into a wellbore. The combination conduit includes a first conduit for moving fluid into the wellbore and a second conduit having at least one optical sensing fiber therein. A fluid is moved into the wellbore through the first conduit. A wellbore parameter is measured through a sensor associated with the at least one optical sensing fiber. | 10-29-2009 |
20110162839 | RETROFIT WELLBORE FLUID INJECTION SYSTEM - A fluid injection system for a wellbore includes an adapter configured to be retained in a safety valve landing nipple. The landing nipple is disposed in a production tubing inserted in the wellbore. The adapter includes a first sealed fluid passage between a part of the tubing disposed above the adapter and a first fluid injection line disposed in a part of the tubing below the adapter. The adapter includes a second sealed fluid passage between a part of the tubing below the adapter and a second fluid injection line disposed inside the tubing above the adapter. The second fluid injection line extends to a wellhead at an upper end of the wellbore. | 07-07-2011 |
20110299933 | Method to Stop Wellbore Fluid Leakage from a Spoolable Wellbore Intervention Rod - A method for sealing a conduit in a spoolable wellbore intervention rod includes exposing an interior of the conduit at a location proximate the earth's surface while the spoolable rod is deployed in a wellbore. A curable sealing compound is introduced into the exposed interior of the conduit and the compound is allowed to cure. | 12-08-2011 |
20120227981 | REAL TIME DOWNHOLE INTERVENTION DURING WELLBORE STIMULATION OPERATIONS - A method for completing a wellbore having a plurality of stimulation valves disposed therein at longitudinally spaced apart locations includes moving a spoolable rod into the wellbore. The rod includes a plurality of spaced apart sensors therein. At least one valve operating dart is applied to an exterior of the spoolable rod. The dart is configured to engage a selected one of the stimulation valves. A position of the at least one dart is estimated during pumping of fluid into the wellbore by measuring output of the sensors in the rod. | 09-13-2012 |
20130251547 | Liquid Lift Pumps for Gas Wells - A wellbore liquid lift pump includes a pump chamber disposed in a wellbore at a selected longitudinal position and within a liquid column therein. The pump chamber has one way valves proximate each longitudinal end thereof. One of the one way valves is in fluid communication with the liquid column. The other one way valve is in fluid communication with a conduit extending from the pump chamber to the surface. The pump includes means for displacing a volume of the pump chamber by application of pressure thereto. The pressure provided by at least one of a gas and a liquid having a density lower than liquid within the liquid column. | 09-26-2013 |
20140127065 | SINGLE AND MULTI-CHAMBER WELLBORE PUMPS FOR FLUID LIFTING - A wellbore pump includes a pump housing suspendible in a wellbore at ends of at least one of a power fluid line and a fluid discharge line. The pump housing includes a fluid inlet proximate a bottom end thereof and wherein the fluid discharge line is coupled proximate a top end thereof. The pump include valves for directing flow of wellbore fluid out of the housing when power fluid displaces fluid in the housing, the valves for directing flow of wellbore fluid into the housing when power fluid pressure is relieved. | 05-08-2014 |
