ISSUE: EOG resources is currently executing a downspacing and infill drilling program. During this process the new infill wells are being hydraulically fractured offset to existing/producing wells.
The existing wells in close proximity to the new infill wells are shut in during the drilling and completion process.
Pressure pulses have been noted in the existing shut-in wells during this process. Due to the pressure pulses, sand from the completions in the original wells can become dislodged and enter the wellbore. When sand enters the existing wellbore it can damage pumping equipment and/or plug the wellbore. When this occurs wellbore intervention is required to replace the damaged equipment and may also require the wellbore to be cleaned out, both operations are costly and slow the process of returning offset wells to production.
PROPOSAL: As a mitigation measure, EOG is requesting approval to fill the existing wellbore with produced water from nearby producing wells. The fluid would increase the hydrostatic pressure in the existing well and assist in counter-acting the pressure pulses and sand influxes impacting the well from the drilling and completion process of the infill wells.
The fluid will be pumped at a very low surface pressure with a fluid pump. Pumping pressures are planned below 500 psi. At or before reaching 500 psi, pumping would cease, keeping the pressure below fracture pressure.
Produced water will be transported by truck or pipeline for the process.
Production profile for this well (#17222) for past year or so:
