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.

Metal-to-metal annulus wellhead style seal with pressure energized from above and below

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.

Embodiments disclosed herein relate to one or more embodiments and methods to make downhole measurements. Embodiments disclosed herein relate to one or more embodiments and methods to measure the movement generated by a coring tool. The methods and embodiments include disposing a coring tool in a wellbore, coupling a first wave detector to the coring tool, anchoring the coring tool to a formation surrounding the wellbore, operating the coring tool, measuring movement generated by the coring tool with the first wave detector, and outputting a signal based upon the measured movement measured with the first wave detector.

Apparatus and method for acoustic measurements while using a coring tool

Subterranean oilfield high-temperature devices configured or designed to operate at elevated temperatures downhole in a well traversing a formation. A tool conveyance is configured for deployment in the well with a downhole cartridge comprising high-temperature sensitive components. A downhole cooling system includes a cooling fluid conduit having a first end configured for fluid connection with a source of cooling fluid and a second end configured for discharging cooling fluid in the well at at least an upper portion of a subterranean high-temperature zone such that cooling fluid circulates in the high-temperature zone.
