Filed:

Dec 28, 2006

Appl. No.:

11/617372

Inventors:

Theodore Lafferty - Sugar Land TX, US
William Underhill - Richmond TX, US
Les Nutt - Houston TX, US
Alejandro Martinez - Victoria TX, US

International Classification:

E21B 47/01
E21B 47/10
E21B 49/00

US Classification:

1662501, 1663081, 166387, 166384, 166 66, 1662801, 7315239

Abstract:

A technique that is usable with a well includes deploying an assembly into a wellbore. The assembly includes at least one sensor. A fracturing fluid is injected under pressure into the wellbore to hydraulically fracture a subterranean formation of interest. The technique includes isolating the sensor from the fracturing and measuring acoustical energy that is generated by the hydraulic fracturing using the sensor(s).

B65G 53/00

US Classification:

166283, 166 7511, 166 901, 406 51

Abstract:

A mechanism for pressurized delivery of material into a well without exposure to a high pressure pump. The mechanism may include material delivery equipment that is coupled to the high pressure pump or other pressure inducing equipment through a material carrier that intersects a fluid line from the pump. The material carrier may include chambers that are reciprocated or rotated between positions that are isolated from the fluid line and in communication with the fluid line. While isolated from the fluid line, the chambers may be filled with oilfield material which may then be delivered to the fluid line when positioned in communication therewith. In this manner, a supply of the oilfield material may be retained in a substantially isolated state relative to the pump and components thereof which may be susceptible to damage from exposure to the oilfield material.

International Classification:

E21B 33/04
B23H 1/00
F16J 15/28
B23B 1/00

Abstract:

A system is disclosed as including a seal for sealing an area between a hanger and a housing of a wellhead. The seal is provided with at least a notch that defines at least a movable portion such as a wing or a lip. An e-ring is provided for a first energizing of the seal. The movable portion enables pressurized fluid from beneath the seal to cause the movable portion to protrude further against a mating side in the wellhead and the hanger for a second energizing of the seal. This type of seal maintains or improves the sealing of the wellhead in high pressure applications. Methods applied to the above seal are also disclosed.

Assignee:

Baker Hughes Oilfield Operations LLC - Houston TX

International Classification:

E21B 33/043
E21B 33/038
E21B 33/12

Abstract:

A system is disclosed as including an enclosed space within a seal for sealing an area between a hanger and a housing of a wellhead. The enclosed space traverses a first section of the seal, a middle section of the seal, and an opening at a second section of the seal. A port is provided as accessible from the housing. A tool positions the seal within the hanger and the housing so that the port is able to access the enclosed space from the housing to the hanger. A pressure applicator applies fluid into the port at a pressure, which is monitored to determine integrity of the seal. In a monitoring mode, a pressure is monitored at the port. A change in the pressure from an ambient pressure at the port may indicate an on-going issue with the seal. Methods applied to the system are also disclosed.
