Abstract

Claims (44)

1. A method comprising:

drilling a wellbore of a well from a surface to form a fluid communication path from a pressurized reservoir to the surface;

installing a first pipe component in the wellbore to form a first annular space between a pipe outside diameter and the wellbore wherein the first annular space is in fluid communication with the pressurized reservoir;

transmitting, by a control system, a first command to a pressure recorder configured to generate annular pressure data of an annular fluid in the first annular space;

transmitting, by the control system, a second command to the pressure recorder, wherein the first command and the second command are separated by a predetermined time duration;

generating, in response to receipt of the first command, first annular first pressure data using the pressure recorder;

generating, in response to receipt of the second command, first annular second pressure data using the pressure recorder;

obtaining, by the control system in response to transmitting the first command, the first annular first pressure data from the pressure recorder;

obtaining, by the control system in response to transmitting the second command, the first annular second pressure data from the pressure recorder;

comparing, using the control system, the first annular first pressure data and the first annular second pressure data with a first set of predetermined criteria;

controlling, using the control system, a first control valve in fluid communication with the first annular space in response to the comparing; and

filling a relief tank using the annular fluid flowing through a fluid conduit in fluid communication with the first annular space, the first control valve, and the relief tank.

2. The method of claim 1 , further comprising:

installing a second pipe component in the first pipe component to form a second annular space between a second outside diameter and a first pipe inside diameter wherein the second annular space is in fluid communication with the pressurized reservoir;

transmitting, by a control system, a first command to a pressure recorder configured to detect an annular pressure of an annular fluid in the second annular space;

transmitting, by the control system, a second command to the pressure recorder, wherein the first command and the second command are separated by a predetermined time duration;

obtaining, by the control system in response to transmitting the first command, second annular first pressure data from the pressure recorder;

obtaining, by the control system in response to transmitting the second command, second annular second pressure data from the pressure recorder;

comparing, using the control system, the second annular first pressure data and the second annular second pressure data with a set of predetermined criteria; and

controlling a control valve in fluid communication with the first annular space in response to the comparing; and

filling a relief tank using the annular fluid flowing through a fluid conduit in fluid communication with the second annular space, the control valve, and the relief tank.

3. The method of claim 2 , further comprising:

performing a workover operation based on a well simulation, using the second annular first pressure data, the second annular second pressure data, and pipe component data at the second annular space.

4. The method of claim 1 , further comprising:

performing a well simulation of the wellbore in one or more wells for a bleed-off rate using the first annular first pressure data, the first annular second pressure data, the predetermined time duration, pipe component data, and annular fluid data; and

determining a predicted tank capacity of the relief tank for the one or more wells using the well simulation.

5. The method of claim 1 , further comprising:

performing a well simulation of the wellbore of one or more wells for a bleed-off rate using the first annular first pressure data, the first annular second pressure data, the predetermined time duration, pipe component data, and annular fluid data; and

determining a predicted tank fluid disposal time frequency for the one or more wells using the well simulation.

6. The method of claim 1 , further comprising:

performing a well simulation of the wellbore of one or more wells for a bleed-off rate using the first annular first pressure data, the first annular second pressure data, the predetermined time duration, pipe component data, and annular fluid data; and

determining a set of tank material properties for the one or more wells using the well simulation.

7. The method of claim 1 ,

wherein the control system adjusts one or more production parameters of a production operation at the wellbore based on the first annular first pressure data, pipe component data, and/or well simulations of the wellbore of one or more wells at the first annular space.

8. The method of claim 1 , further comprising:

performing a workover operation based on a well simulation, using the first annular first pressure data, the first annular second pressure data, and pipe component data at the first annular space.

9. The method of claim 1 , further comprising:

transmitting, using a control system, a first command to a contaminant detector in fluid communication with the annular fluid;

obtaining, by the control system in response to transmitting the first command, contaminant data of the annular fluid from the contaminant detector;

comparing, using the control system, the contaminant data with a set of predetermined criteria;

controlling, using the control system, a scavenger disposed on the fluid conduit, in response to the comparing; and

treating the annular fluid to scavenge contaminant from the annular fluid.

10. The method of claim 1 , further comprising:

operating the well using the control system, the pressure recorder, the first control valve, the fluid conduit, and the relief tank.
