Horizontal Wells Productivity Enhancement

OVERVIEW

A Permian Basin operator had been witnessing solids deposition issues within the bottom third section of the tubing and below the EOT, resulting in many cases in tubing and equipment failures, and significant solid blockages. Wellbore cleanouts along the curvature (below the EOT), production chemistry analyses, and in some cases buildup tests indicated the possibility of significant solids deposition along the lateral and near wellbore (skin damage).

Solutions:

Quantified potential production enhancement through stimulation.

Performed a throughout review of the well’s operations history and production chemistry analyses.

Identified well damage mechanisms.

Formulated remedial treatment and developed treatment procedures.

Developed guidelines for wellbore cleanouts and diversion.


Results:

The remedial treatments yielded sustained production uplift of up to 80% above the pre-treatment production.
