US 12,607,094 B1 · System and method for managing tools

Abstract

Methods, systems, and computer readable storage mediums for managing testing of a well to facilitate completion of the well is disclosed. The system may include a tool usable to perform testing on the well. The tool may include a circulation assembly, a primary control assembly, and a secondary control assembly. The circulation assembly may be reconfigurable by selectively isolating an annulus of the well from a fluid chamber of the circulation assembly. The primary control assembly may facilitate reconfiguration of the circulation assembly to selectively isolate the annulus, and facilitate flowing of various fluids and gasses to perform the testing. The secondary control assembly may serve as a partial backup for the primary control assembly usable to address undesired conditions in the well when the primary control assembly is unable to reconfigure the circulation assembly independent to address the undesired conditions.

Dependent claims

A tool for use with respect to a well, the tool comprising:

a circulation assembly adapted to reversibly place a fluid line to a surface facility in fluid communication with an annulus;
a primary control assembly adapted to control the circulation assembly to reversibly place the fluid line to the surface facility in fluid communication with the annulus;
and
a secondary control assembly comprising:
an actuator adapted to override the control of the circulation assembly by the primary control assembly to control the circulation assembly while the primary control assembly is unable to control the circulation assembly;
and
an arming component adapted to actuate the actuator, wherein the actuator comprises:
a valve assembly operably connected to flowlines between the circulation assembly and the primary control assembly, the flowlines enabling the primary control assembly to control operation of the circulation assembly,
wherein the valve assembly, when actuated by the arming component, is adapted to:
isolate a first flowline of the flowlines from the fluid line;
and
place a second flowline of the flowlines in fluid communication with the annulus.

A method of managing testing of a well that is positioned with a geological formation, comprising:

while a tool is positioned in the well for the testing:
making an identification that a primary control assembly adapted to control a circulation assembly to reversibly place a fluid line to a surface in fluid communication with an annulus has lost an ability to control the circulation assembly;
based on the identification:
activating an arming component of a secondary control assembly of the tool to override the control of the circulation assembly by the primary control assembly to control the circulation assembly while the primary control assembly is unable to control the circulation assembly, wherein the arming component is adapted to actuate an actuator, the actuator being adapted to override the control of the circulation assembly by the primary control assembly to control the circulation assembly while the primary control assembly is unable to control the circulation assembly, and wherein the actuator comprises:
a valve assembly operably connected to flowlines between the circulation assembly and the primary control assembly, the flowlines enabling the primary control assembly to control operation of the circulation assembly,
wherein the valve assembly, when actuated by the arming component, is adapted to:
isolate a first flowline of the flowlines from the fluid line;
and
place a second flowline of the flowlines in fluid communication with the annulus;
and
after activating the arming component:
pumping from a surface facility to actuate the circulation assembly to place the fluid line to the surface in fluid communication with the annulus.
