| A hydraulic anchor is coupled to a packer subassembly of a tool string. The hydraulic anchor, when actuated by fluid pressure, engages the surrounding wellbore, holding the tool string in place within the wellbore. A packer may then be actuated, held in position within the wellbore by the hydraulic anchor. In some embodiments, an inflatable packer may be held in the desired location by the hydraulic anchor. In some embodiments, a straddle packer assembly may be held in place by the hydraulic anchor. In some embodiments, a swellable packer may be held in place during the swelling process by the hydraulic anchor. | ||||||

Provided herein are methods of formulating a sealant to span an opening and form a seal with surfaces across the opening including selecting a fluid material capable of contacting and adhering to the surface of the opening and which reacts to form a solid material as a result of a thermal reaction, and selecting and intermixing one or more solids with the fluid material to form a composite, wherein the composite cures from a fluid to a solid and bond to the surfaces of the opening and the change in volume of the composite as the temperature thereof changes during curing is insufficient to cause it to pull away from the surfaces of the opening or fail internally.

| A safety valve assembly for extradition of hydrocarbons includes a valve body including a passage duct, configured to be traversed by a production and/or drilling line. The valve body includes housings for a punch and counter-punch, arranged diametrically opposite to one another with a common longitudinal axis substantially perpendicular to the longitudinal axis of the valve. The punch slides linearly in a controlled manner in the housing along the axis which intersects the longitudinal axis of the pipe, and the counter-punch slides linearly in a controlled manner in the housing along the axis which intersects the longitudinal axis of the pipe. The punch and counter-punch are configured to allow the counter-punch to slidingly receive the punch in its interior to create two different shearing planes. The counter-punch includes a hollow part to slidingly receive the section of tubular material and the punch, in the linear movement during the shearing operation. | ||||||

The present disclosure relates to seals and sealing arrangements, especially those used in wireline valves. The seal comprises an elastomeric seal body with a sealing surface, a plurality of generally planar inserts embedded within the elastomeric seal body adjacent the sealing surface, and having elastomeric seal material disposed between the plurality of generally planar inserts. The generally planar inserts may have a slightly wedge shape and may be embedded into the elastomeric seal body in a generally fan-shaped orientation. They may be orientated such that upon contacting a substantially tubular shaped body to be sealed around and the subsequent deformation of the seal body about said substantially tubular shaped body, the plurality of generally planar inserts become orientated such that they extend radially from the substantially tubular shaped body.
