摘要： Casing valves for selective well stimulation and control. A well system includes at least one valve interconnected in a casing string operable via at least one line external to the casing string to selectively control fluid flow between an exterior and interior of the casing string, and the casing string, valve and line being cemented in a wellbore. A method of selectively stimulating a subterranean formation includes: positioning a casing string in a wellbore, the casing string including spaced apart valves operable via a line to selectively control fluid flow between an interior and exterior of the casing string; and for each of multiple intervals of the formation in sequence, stimulating the interval by opening a corresponding one of the valves, closing the remainder of the valves, and flowing a stimulation fluid from the casing string into the interval.

摘要： A method of selectively actuating well tools includes the steps of: selecting a well tool for actuation by current flow in one direction through a set of conductors; and selecting another well tool for actuation by opposite current flow through the set of conductors. A system includes multiple control devices that control which well tool is selected for actuation in response to current flow in at least one conductor set. A current direction in the conductors selects a certain well tool for actuation. A method of using n conductors to selectively actuate n*(n−1) well tools includes the steps of: arranging the conductors into n*(n−1)/2 sets; connecting the conductor sets to respective groups of the well tools; and controlling direction of current flow through at least one of the sets of conductors, thereby selecting at least one well tool in the respective group of the well tools for actuation.

摘要： An annulus vortex flowmeter for use in conjunction with a subterranean well. A flowmeter includes a housing, a vortex responsive structure which vibrates in response to vortices produced external to the housing and a sensor which senses vibration of the structure and produces a signal indicative of a flow rate. A method of measuring fluid flow rate between a tubular string and a zone intersected by a wellbore includes utilizing a flowmeter having a vortex shedding device external to a housing for interconnection in the tubular string, the flowmeter including a vortex responsive structure which vibrates in response to vortices produced by the vortex shedding device as the fluid flows through an annulus external to the housing, and a sensor which senses vibration of the structure and produces a signal indicative of the rate of flow of the fluid; and determining the flow rate based on the sensor signal.
