Abstract: Techniques for correlating changing hydraulic pressure differentials with interval control valve (ICV) movements are contemplated. In some aspects, the disclosed technology includes include methods for applying, by a surface controller, a series of differential pressure values to a hydraulic-open line, receiving, from a position sensor, a corresponding valve position for each of the differential pressure values, and calculating a lag time, a move speed and a response delay for each of the first series of differential pressure values. In some aspects, the method can further include steps for generating an ICV positioning model based at least in part on the lag time, the move speed, and the response delay calculated for each of the first series of differential pressure values. Systems and computer-readable media are also provided.

Abstract: A control module for operation of downhole well tools and apparatuses is disclosed. The control module can control multiple tools, electronics, subs, etc. based on one electronic input and optionally one hydraulic input from the wellhead or surface. The control module can transmit along selected electronic lines and optionally hydraulic lines in order to control specific apparatuses of the downhole well tools. By allowing a single electronic line from the surface or shut in to control multiple tools, total electronic complexity is reduced. A three conductor control module can control operations of up to twelve downhole tools, and a two conductor control module can control operations of up to six downhole tools, in some embodiments.

Abstract: A spoolable array of sensors may be deployed within a wellbore and external a tubular string for measuring properties of a fluid in the central flow passage of the tubular string. A flow port may be made in the tubular string passing from the central flow passage to the external surface.
