Abstract: A contracting tubing includes an outer pipe, an inner pipe, and an intermediate layer positioned between the outer pipe and the inner pipe. The intermediate layer includes an elastomer that is swellable in a fluid. A method for using the contracting tubing includes opening a fluid passage in the contracting tubing to the intermediate layer to contact the intermediate layer with a fluid and swell the elastomer. The swelling of the elastomer applies a force on the inner pipe and contracts the inner pipe, such that the inner pipe has a first inner diameter prior to contacting the intermediate layer with the fluid and a second inner diameter smaller than the first inner diameter after contacting the intermediate layer with the fluid.

Abstract: Computer-implemented systems and computer-implemented methods include the following. A choke/pressure control valve (PCV) gas rate is determined for each well of a group of producing wells. A downstream temperature (DST) gas rate is determined for each well of the group of producing wells. Parameters for a well rate test are determined for each well of the group of producing wells using the choke/PCV gas rate and the DST gas rate. A total gas rate for the producing wells is determined using the parameters. A gas production allocation factor (G-PAF) for the producing wells is determined. A production allocation for each well of the producing wells is determined using the total gas rate.

Abstract: Systems and methods for finding and solving problems with wet gas venturi meters in one or more gas well sites include one or more gas well sites configured to supply gas to a gas plant, each gas well site comprising a gas well connected to a piping, one or more valves installed on the piping, one or more pressure sensors, one or more temperature sensors, one or more venturi meters configured to measure a differential pressure of the gas in the piping, and one or more programmable logic controllers configured to receive the measured data from the pressure sensors, temperature sensors, and the venturi meters, receive a plurality of dimensions of the one or more venturi meters, receive a plurality of fluid properties values and, determine a first gas rate and first condensate rate for each of the well sites.
