Abstract
A computerized method for management of a slurry injection well and the associated surface facility. The method utilizes real time and historical data of injection and slurry parameters in conjunction with computer simulations on a computer-modelled reservoir to predict well behavior during one or a series of injection events. The system determines optimized injection operation schedules, recommends and implements changes to an injection operation, including while in process such as through automated equipment control.
Claims8
A system, comprising:
- a wellbore within a subsurface region having one or more formations;
- an injection control system for controlling injection operations comprising injections of waste slurry into the wellbore and the subsurface region, wherein the injection control system is operable to control surface equipment to regulate injection slurry volume, injection pressure, injection duration, and injection rate;
- one or more sensors operable to acquire data associated with one or more properties of the waste slurry;
- and
- one or more sensors operable to acquire data associated with one or more operations of the control surface equipment of the injection control system;
- and
- one or more processors configured to:
- receive the data associated with one or more properties of the waste slurry;
- and
- one or more operations of the surface equipment;
- generate a geomechanical computer model of the subsurface region;
- and
- simulate an injection operation performed in the subsurface region modeled by the computer model;
- and
- in response to the simulation of the injection operation computer model, automatically adjust operation of the control surface equipment of the injection system.
A method of controlling injection operations in a wellbore extending through a subsurface region having one or more formations, the method comprising:
- receiving data at a control computer having a non-transitory memory, a processor, and a software program executable by the control computer, the data associated with:
- one or more properties of a waste slurry for injection into the wellbore and subsurface region;
- and
- operations of surface injection equipment;
- in response to receiving the data:
- generating a geomechanical computer model of the subsurface region;
- and
- simulating an injection operation performed in the subsurface region modeled by the computer model;
- and
- in response to simulating the injection operation, automatically adjusting an operation of the surface injection equipment;
- in response to adjusting the operation of the surface injection equipment, regulating a slurry volume, an injection pressure, an injection duration, and an injection rate of the waste slurry.
