Abstract
A logging system for a subsurface operation includes: a probe positioned within a wellbore extending through a target formation, the probe generating pressure pulses that propagate within a target formation proximate to the wellbore; and a wireline extending along at least a portion of the wellbore. The wireline detects the pressure pulses and generates an electrical signal indicative of an effective flowing thickness of the target formation.
Claims5
A logging system for a subsurface operation, the logging system comprising:
- a probe configured to be positioned within a wellbore extending through a target formation, the probe further configured to generate pressure pulses to propagate within the target formation proximate to the wellbore by injecting fluid into the wellbore;
- a wireline configured to:
- extend along at least a portion of the wellbore;
- detect the pressure pulses by measuring a strain caused by compression of the wireline as the pressure pulses propagate through the target formation;
- and generate a signal indicative of an effective flowing thickness of the target formation, the wireline comprising a fiber cable configured to transmit the signal;
- and
- testing equipment coupled to the wireline and configured to detect permeability and fluid composition of the target formation.
