Abstract: A sealing system for fluidly sealing a portion of a wellbore including a housing, a rupture disc disposed within a housing inner bore, and a plug disposed within the housing inner bore. The rupture disc includes a base and a central portion, which extends across the housing inner bore to fluidly seal the housing inner bore in a sealed state. The plug fluidly seals the housing inner bore in the sealed state. The plug is disposed an axial distance from the rupture disc in the sealed state. In some embodiments, a sleeve is disposed within the housing inner bore. A central bore of the sleeve retains the plug in the sealed state. Upon a release event, the plug is released from the sleeve. The release of the plug triggers a rupture event, which fractures the rupture disc. The plug clears rupture disc fragments.

Abstract: A downhole separation system for use upstream of any tool through which a media flows. The separation system filters at least a portion of any solids from the media flowing through a filter flow path. The separation system flushes at least a portion of the filtered solids through a flush flow path, through a flush outlet on an outer surface of a housing, and into a space surrounding the housing. A screen and an activation mechanism are disposed within a housing inner bore. The filter flow path extends through a plurality of openings in the screen. The activation mechanism is configured to move between a default position in which it directs fluid through the filter flow path and an activated position in which it directs fluid through the flush flow path. Optionally, a spring within the housing inner bore is configured to bias the activation mechanism toward the default position.

Abstract: A rupture disc configured to fluidly seal a passageway. The rupture disc includes a base extending from a distal surface to a proximal end, and a central portion extending across the proximal end of the base. The central portion traverses a central axis defined by the base. At least one surface of the central portion, such as an outer surface or inner surface, includes a plurality of facets defined by a plurality of seams. The facets may include one or more flat surfaces and/or one or more conical surfaces. A rupture disc system for fluidly sealing a portion of a wellbore includes the rupture disc disposed within and extending across a housing central bore of a housing, with one or more sealing members engaging the rupture disc and an inner surface of the housing central bore to fluidly seal the housing central bore.

Abstract: A downhole tool includes a valve assembly and a shock absorbing assembly. The valve assembly includes a valve spring operatively connected to a valve body. The shock absorbing assembly includes a spring operatively connected to a shock absorbing body having a fluid passage therethrough. The valve body is configured to selectively engage the shock absorbing body to create a fluid tight seal over the fluid passage in a first position, and to allow a fluid flow through the fluid passage in a second position. The repeated movement cycle of the selective engagement between the valve body and the shock absorbing body generates a pressure pulse or a varying pressure differential across the downhole tool. The repeated movement cycle is powered by a fluid flow. The tool may be selectively activated and deactivated.

Abstract: A stabilizer assembly for a tubular member includes a stabilizing body dimensioned to fit around the tubular member, a central portion having a radial projection, and a first end having a first threaded outer surface and a set of integral first elastic members. A first nut member includes a proximal end with a threaded inner surface configured to engage the first threaded outer surface of the stabilizing body and a central portion with a first tapered inner surface configured to engage the first elastic members of the stabilizing body. Threading the first nut member onto the first end of the stabilizing body forces the first elastic members to engage the first tapered inner surface of the first nut member thereby radially flexing the first elastic members to engage the tubular member. An inner surface of a distal end of each first elastic member may include a grip section.
