Abstract:
This case study demonstrates the successful identification and isolation of water ingress in a high-rate gas producer using a novel integration of spectral acoustics and thermal-hydrodynamic modeling. Facing significant water production and the limitations of conventional sensors, operators deployed a through-barrier diagnostic system inside the 7 5/8” casing to locate flow sources behind pipe.
The diagnostic approach utilized Chorus X spectral acoustics to conduct radial distance analysis, isolating high-intensity signals in the "far acoustic domain." This specialized assessment spatially resolved reservoir flow patterns distinct from near-zone completion flow events, treating all acoustic energy as interpretable signals to pinpoint primary water sources at two distinct stratigraphic depths. These acoustic findings con-strained a Cascade thermal-hydrodynamic model, which numerically solved coupled equations to quantify the reservoir flow distribution and confirm the ingress points.
The high-resolution data provided by this tandem workflow eliminated the uncertainties associated with conventional sensors restricted to wellbore measurements. This precise characterization facilitated a targeted remedial program—comprising perforating and a cement squeeze—to isolate the identified water-bearing zones. The intervention was successful, drastically reducing water cut and returning the well to productive operations. The results validate the capability of combining far-field acoustics with numerical modeling to resolve complex flow scenarios in mature assets.
