摘要： Described herein are embodiments of systems and apparatuses that include a dart and/or a clutch for a dart plunger. In an exemplary embodiment, the clutch consists of a one-piece unit having a length, an outside diameter, and an inside diameter where at least a portion of the inside diameter is sized to create a frictional interface with a dart. The clutch may also include a gap, a slot, and/or a spiral cut. The dart may include a shaft having opposite ends and a shaft diameter that varies between the opposite ends.

摘要： The invention relates to systems and apparatuses that include a manifold block. The manifold block includes a production line flow path and a flow path from a wellhead to a lubricator. The manifold block further includes an insert region configured to receive a removable flow restrictor wherein the insert region is separate from the production line flow path and the flow path from the wellhead to the lubricator.

摘要： An electrically operated catcher mechanism that is part of a lubricator and catcher unit used in conjunction with a bypass plunger in an oil or gas well include an electrically operated mechanism to move between the catch and release positions. The electrically operated catcher mechanism includes a cam rotated by a motor which causes the device to move between catch and release positions.

摘要： A plunger lift lubricator having an internal bypass configuration which enables a plunger to be reliably captured and while still allowing the flow of fluid up through the lubricator before the fluid is directed radially outward and down the internal bypass passageways. The lubricator can comprise both an upper flow path and a lower flow path and can be configured such that a plunger can travel all the way up to shift a valve in the plunger if needed.

摘要： A bypass plunger includes a unitary or one-piece hollow body-and-valve cage, which retains a dart valve within the valve cage portion of the hollow body using a threaded retaining nut that is secured to the hollow body by crimple detents. A series of helical grooves surround the central portion of the outer surface of the hollow body of the plunger to control spin during descent. A canted-coil-spring disposed within the retaining nut functions as a clutch. The valve cage includes ports that may be configured to control flow through the plunger during ascent.

摘要： A downhole apparatus for collecting solids fallback in the tubing of an oil producing borehole comprises two or more baskets to collect the solids fall back, each basket partially occupying a portion of the inner cross section of the tubing, leaving a portion of the inner cross section of the tubing having an unrestricted flow path. The baskets when considered in plan view along longitudinal axis of the tubing are distributed such that together they cover substantially the whole area of the tubing while leaving an unobstructed non-straight flowpath around the baskets.

摘要： Geothermal production monitoring systems and related methods are disclosed herein. An example system includes a production well, an injection well, a downhole pump or a downhole compressor to control a production of a multiphase fluid including steam from the production well, a first fluid conduit to transport the multiphase fluid away from the production well, a surface pump disposed downstream of the first fluid conduit, and a second fluid conduit. The surface pump is to inject water into the injection well via the second fluid conduit. A flowmeter is fluidly coupled to the first fluid conduit. The example system includes a processor to control at least one of (a) the downhole pump or the downhole compressor or (b) the surface pump in response to fluid property data generated by the first flowmeter.

摘要： A packer, disposed in a deviated portion of a well, seals with an inner wall of the well. A first tubular, extending through the packer, receives a wellbore fluid via first inlet. A first outlet of the first tubular discharges the wellbore fluid into an annulus within the well, uphole of the packer. A second tubular, coupled to the first tubular, receives at least a liquid portion of the wellbore fluid via a second inlet. The second tubular directs the liquid portion of the wellbore fluid to a downhole artificial lift system. A sump, defined by a region of an annulus between the inner wall of the well and the first tubular, receives at least a portion of solid material carried by the wellbore fluid.
