Liner top diagnostic tool

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• running inflow packers in a locked position downhole into a well;
• running a liner top diagnostic tool (LTDT) in a drill pipe to a desired depth in the well;
• dropping, using a string, a lower-packer-sized ball to activate a lower inflow packer into a well assembly;
• pressure-testing a back side of the lower inflow packer assembly to ensure a seal integrity;
• unsetting the lower inflow packer by withdrawing a string weight while rotating the string;
• displacing the string to test fluid to the end of the string, and applying weight and rotation to set the lower inflow packer;
• establishing a Horner plot based, at least in part, on performing an inflow test;
• dropping a deactivation-sized ball into the well to deactivate the lower inflow packer included in the well assembly;
• activating an upper inflow packer assembly using upper-packer-sized balls;
• and
• identifying a leak into the well based, at least in part, on testing liner tops.

A computer-implemented system, comprising:

• one or more processors;
• and
• a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instructing the one or more processors to perform operations comprising:
• running inflow packers in a locked position downhole into a well;
• running a liner top diagnostic tool (LTDT) in a drill pipe to a desired depth in the well;
• dropping, using a string, a lower-packer-sized ball to activate a lower inflow packer into a well assembly;
• pressure-testing a back side of the lower inflow packer assembly to ensure a seal integrity;
• unsetting the lower inflow packer by withdrawing a string weight while rotating the string;
• displacing the string to test fluid to the end of the string, and applying weight and rotation to set the lower inflow packer;
• establishing a Horner plot based, at least in part, on performing an inflow test;
• dropping a deactivation-sized ball into the well to deactivate the lower inflow packer included in the well assembly;
• activating an upper inflow packer assembly using upper-packer-sized balls;
• and
• identifying a leak into the well based, at least in part, on testing liner tops.
