Boiler plate sundry form for these EOG wells throughout the Parshall oil field. This is from a sundry form dated May 10, 2019, but I've seen the same boiler plate language for at least the past three years, it seems:

EOG is currently executing a downspacing and infill drilling program. During this process, the new infill wells are being hydraulically fractured offset existing / producing wells. The existing wells in closest 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 this occurs wellbore intervention is required to replace the damaged pumping 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.

In addition, the low energy system often requires artifical life (rod pump or ESP) which can be difficult to operate with sand production.

As a mitigation measure, EOG is requesting approval to fill the existing wellbore with water and to have the option to use a temporary diverter. The water would increase the bottom hole pressure in the existing well, counteracting the pressure pulses and sand influxes impacting the well from the drilling and completion process of hte infill wells.

Surface-hole pressure will be maintained below EOG's designated pre-fill pressure paramets noted in Figure 1 based on the set tubing depth of the referenced well. The referenced well is connected ao Supervisory control and Data Acquision (SCADA) system which is monitored 24/7. The automated pump kill pressure is set at 90% of total surface pressure. Water will be transported by truck or pipeline for the process.
