## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The system of claim 1, wherein the control surface equipment comprises waste slurry preparation equipment operable to prepare the waste slurry, wherein the one or more processors are operable to control the waste slurry preparation equipment to adjust the one or more properties of the waste slurry.

### Claim 4 (depends on 2)

The system of claim 2, wherein the one or more processors are operable to continuously adjust the operation of the injection control system based on the geomechanical model that is continuously generated based on the received data.

### Claim 5 (depends on 2)

The system of claim 2, wherein the surface equipment of the injection control system comprises a pump configured to: control the injection rate in which the waste slurry is pumped into the wellbore; control the injection slurry volume of the waste slurry being pumped into the wellbore; or any combination thereof.

### Claim 6 (depends on 2)

The system of claim 2, comprising a mechanism operable to filter solids from fluids extracted from the wellbore, wherein the one or more processors are operable to control an operation of the mechanism.

### Claim 7 (depends on 2)
