  • Patent number: 12006481
    Abstract: A method may include producing a crude oil from a reservoir and contacting the crude oil with a demulsifying agent before the crude oil passes through a production choke valve to form a mixture of crude oil and demulsifying agent. The mixture of crude oil and demulsifying agent may be separated in one or more separators into a gas stream, an oil stream, and a water stream. The gas stream and oil stream may be combined to form an oil and gas mixture.
    Type: Grant
    Filed: November 30, 2022
    Date of Patent: June 11, 2024
    Assignee: SAUDI ARABIAN OIL COMPANY

  • Patent number: 11885210
    Abstract: A water separation system includes a production control valve fluidly connected to a production tubing and positioned at an uphole end of the production tubing at a well head of a well site, a production fluid pathway between the production control valve and a water separator, an injection control valve fluidly connected to an injection tubing and positioned at an uphole end of the injection tubing at the well head, and an injection fluid pathway between the injection control valve and the water separator. The water separator is positioned at the well site and is fluidly connected to the production fluid pathway and the injection fluid pathway. The water separator separates water from the production fluid and directs the separated water to the injection fluid pathway. An output fluid pathway fluidly connects to the water separator to direct the production fluid out of the water separator.
