20090218089 | Phase-Controlled Well Flow Control and Associated Methods - Phase-controlled well flow control. A well system includes a flow control device which regulates flow of a fluid in the well system, the flow control device being responsive to both pressure and temperature in the well system to regulate flow of the fluid. A flow control device includes a flow regulator for regulating flow of a fluid through the flow control device, and an actuator which is operative to actuate the flow regulator in response to a predetermined relationship between a phase of the fluid and both pressure and temperature exposed to the actuator. A method of controlling a phase change of a fluid in a well system includes the steps of: flowing the fluid through a flow control device in the well system; and adjusting the flow control device in response to both pressure and temperature in the well system. | 09-03-2009 |
20100163250 | WELL EQUIPMENT FOR HEATED FLUID RECOVERY - A device has a first elongate tubular body and a second elongate tubular body coupled to the first tubular body, both adapted to reside in the wellbore. The device is changeable between the first tubular body axially fixed against movement in a first direction relative to the second tubular body and axially moveable in the first direction relative to the second elongate tubular body in response to temperature. | 07-01-2010 |
20110005755 | Downhole Casing Cutting Tool - An oilfield downhole cutting tool is provided. The cutting tool comprises a tool body that comprises a non-cutting stabilizing section. The cutting tool further comprises a plurality of cutters coupled to the tool body forward of the non-cutting stabilizing section, wherein a maximum cutting diameter defined by the cutters is less than 1.1 times a diameter defined by the non-cutting stabilizing section. The cutting tool further comprises a cutting rate limiting component coupled to the tool body. | 01-13-2011 |
20110036576 | HEATED FLUID INJECTION USING MULTILATERAL WELLS - A well system includes a main wellbore extending from a terranean surface toward a subterranean zone. A first lateral wellbore extends from the main wellbore into the subterranean zone. A second lateral wellbore extends from the main wellbore into the subterranean zone. A liner junction device resides in the main wellbore and has a first leg extending into the first lateral wellbore and a second leg extending downhole in the main wellbore. A treatment fluid injection string extends from in the main wellbore through the liner junction and into the first lateral wellbore and terminates in the first lateral wellbore. A seal in the first lateral wellbore seals against flow toward the main wellbore in an annulus adjacent an outer surface of the treatment fluid injection string. | 02-17-2011 |

20110186291 | METHODS AND SYSTEMS FOR ORIENTING IN A BORE - Assemblies that can be disposed in a subterranean bore are described. Certain assemblies can be used to orient a second pipe with respect to a first pipe in a bore. A second pipe can be rotationally oriented without breaking one or more control lines that may be associated or included with the second pipe by using a tool that orients the second pipe as the second pipe is moved toward a surface of the bore. In some embodiments, assemblies can be used to orient multiple portions of the second pipe with respect to multiple windows of the first pipe. The first pipe may be a casing string and the second pipe may be a tubing string. | 08-04-2011 |
20110240283 | WELL ASSEMBLY WITH A MILLABLE MEMBER IN AN OPENING - Assemblies that can be disposed in a subterranean bore are described. An assembly can include a body and a member that is made from a different material that the material from which the body is made. The member can be located in an opening in the body and can be coupled to the body. The member coupled to the body can define an inner diameter and form a seal for the inner diameter. The member can be milled to access an environment exterior to the member and the body for example to create a branch wellbore. | 10-06-2011 |
20120193106 | RECOVERING HEATED FLUID USING WELL EQUIPMENT - A device has a first elongate tubular body and a second elongate tubular body coupled to the first tubular body, both adapted to reside in the wellbore. The device is changeable between the first tubular body axially fixed against movement in a first direction relative to the second tubular body and axially moveable in the first direction relative to the second elongate tubular body in response to temperature. | 08-02-2012 |
20120305266 | VARIABLY CONFIGURABLE WELLBORE JUNCTION ASSEMBLY - A method of installing a wellbore junction assembly in a well can include connecting at least two tubular strings to one opposite end of a tubular string connector with similarly dimensioned oriented connections, whereby the tubular strings are interchangeably connectable to the connector by the oriented connections. A wellbore junction assembly can include at least two tubular strings and a tubular string connector having opposite ends. Each of the tubular strings may be secured to one opposite end of the connector by oriented connections, whereby each of the tubular strings has a fixed rotational orientation relative to the connector. A well system can include a tubular string connector, each of first and second tubular strings being secured to the connector, and a support which reduces bending of the second tubular string which results from deflection of the second tubular string from one wellbore section into another wellbore section. | 12-06-2012 |
20120305267 | WELLBORE JUNCTION COMPLETION WITH FLUID LOSS CONTROL - A method of installing a wellbore junction assembly in a well can include inserting a tubular string into a deflector, and opening a flow control device in response to the inserting. A well system can include a deflector positioned at an intersection between at least three wellbore sections, and a tubular string connector having at least two tubular strings connected to an end thereof, one tubular string being received in the deflector and engaged with a flow control device positioned in a wellbore section, and another tubular string being received in another wellbore section. Another method of installing a wellbore junction assembly in a well can include inserting a tubular string into a deflector positioned at a wellbore intersection, then sealingly engaging the tubular string, and then opening a flow control device in response to the inserting. | 12-06-2012 |
