摘要： A method including receiving modeling data, wherein the modeling data includes field instrument data and associated gas flow rate data for a first plurality of wells. The method further includes splitting the modeling data into a train set, a validation set, and a test set and pre-processing the modeling data. The method further includes selecting a machine-learned model and architecture and training the machine-learned model to predict gas flow rates from the pre-processed modeling data using the training set. The method further includes using the machine-learned model to predict gas flow rates using real-time field instrument data from a second plurality of wells, wherein the real-time field instrument data has been pre-processed similarly to the modeling data.

摘要： Disclosed are methods, systems, and computer-readable medium to perform operations including: calculating a total gas flow rate in a testing trap, where the total gas flow rate includes a first gas flow rate in a liquid leg of the testing trap and a second gas flow rate in a gas leg of the testing trap; calculating a total oil flow rate in the testing trap, where the total oil flow rate includes a first oil flow rate in the liquid leg and a second oil rate in the gas leg; comparing the total gas flow rate and the total oil flow rate to a measured gas flow rate and a measured oil flow rate respectively, where the measured gas flow rate and the measured gas flow rate are measured by a multiphase flow meter; and determining, based on the comparison, whether the multiphase flow meter is calibrated.

摘要： Techniques for managing water disposal include circulating a mixed water-oil liquid in a pipeline from a water-oil separation plant toward at least one disposal well that includes a wellbore formed from a terranean surface to a subterranean formation; determining, based on a sampling of the mixed water-oil liquid by an OIW meter, an amount of oil in the mixed water-oil liquid; based on the amount of oil being within a desired amount range: controlling each a choke valve and a surface safety valve to modulate toward an open position, and controlling a recycle valve to modulate to a closed position; and based on the amount of oil being outside of the desired amount range: controlling the choke valve and the surface safety valve to modulate toward a closed position, and controlling the recycle valve to modulate to an open position.

摘要： A production well has nested casings including a first production casing and a first production tubing installed within the first production casing, which extends from a surface to a depth within the wellbore. Before implementing a gas-lift operation in the production well, the first production tubing is removed. A second production casing is lowered within the first production casing. The second production casing has a smaller outer diameter than an inner diameter of the first production casing. From the surface of the wellbore to the depth within the wellbore to which the second production casing extends, the inner diameter of the second production casing is expanded until an outer wall of the second production casing forms a gas-tight seal with an inner wall of the first production casing.

摘要： A surface safety valve for a well system includes a main valve body with a central bore through it. The main valve body has a centerline axis and is configured to be connected at a surface location above a surface of the Earth to a surface assembly of the well system and to receive through the central bore a flow of wellbore fluid from a subterranean zone conveyed by a production tubing. A gate is positioned within the main valve body and is configured to move from an open position in which the gate does not block flow of wellbore fluid through the central bore to a closed position in which the gate blocks flow of wellbore fluid through the central bore. The gate travels from the open position to the closed position along a gate movement axis perpendicular to the centerline bore axis. The gate includes a gate front end positioned on a first side of the centerline bore axis and a gate back end positioned on a second side of the centerline bore axis opposite the first side. The surface safety valve also includes an actuator positioned on the first side of the centerline bore axis. The actuator is configured to selectively push the gate towards the open position. The safety valve also includes a spring enclosed within the main valve body and positioned on the second side of the centerline bore axis. The spring is connected to the gate back end and is configured to bias the gate towards the closed position.
