An expandable tubular includes a plurality of leaves formed from sheet material that have curved surfaces. The leaves extend around a portion or fully around the diameter of the tubular structure. Some of the adjacent leaves of the tubular are coupled together. The tubular is compressed to a smaller diameter so that it can be inserted through previously deployed tubular assemblies. Once the tubular is properly positioned, it is deployed and coupled or not coupled to a previously deployed tubular assembly. The tubular is useful for all types of wells and boreholes.

Expandable tubulars for use in geologic structures

A system for producing a mixed gas-oil stream which contains solid particulates wherein gas is to be separated and compressed downhole in a turbine-driven compressor before the gas is injected into a subterranean formation. The stream is passed through an upstream separator to separate out the particulates which pass through a first and second set of slots into first and second passages, both of which empty into a bypass through the turbine whereby the separated particulates do not contact the rotary vanes of the turbine thereby alleviating the erosive effects of the solids in the produced stream.

Oil and gas production with downhole separation and reinjection of gas

An apparatus and method for making and using two measurements to correct metered flow rate values when liquids are present in a multiphase flow stream. The apparatus includes a conduit ( ), an orifice ( ) positioned within the conduit for creating differential pressure, a gamma ray densitometer including a radient energy source ( ) and a radient energy detector ( ) placed at an upstream side of the orifice for measuring upstream cross-sectional area and a pressure recovery port ( ) placed downstream of the orifice for measuring the pressure recovery value.

Apparatus and method for measuring flow of gas with entrained liquids

A system for controlling the fill of a receptacle cylinder with compressed natural gas (CNG). The flow of gas into the receptacle cylinder is controlled by a fill controller with software configured to calculate the mass of gas to be added to the cylinder as a function of the pressure and temperature in the cylinder during the fill process and to open and close a flow valve in accordance with such calculation.
