Low Risk – No Fear Deepwater Acid Stimulation: New Wells, Old Wells, Producers, Injectors

Includes a Live Event on 11/07/2019 at 9:30 AM (EST)

Acid stimulation, especially with hydrofluoric (HF) acid in sandstone formations, has been around for over 80 years although historically it has been met with trepidation, if not outright fear. This continues to be the case today, especially in high cost, deepwater well completions; resulting in avoidance where applicable, thereby foregoing production uplift opportunities and leaving oil and gas reserves in the ground.

Unfortunately, what is largely unappreciated or at least misunderstood, is that the risks and concerns associated with HF acidizing in such wells can be very reasonably addressed. Low to sub-zero skin, new well completions are very possible – and proven – with pre-frac pack HF acid treatments, for example – not a broad industry practice.  Uplift from existing wells with significant damage skins restricting production (or injection) can be substantial with properly custom-designed HF acid treatments.

The presentation reviews and addresses the real and perceived risks and historical fears in acid stimulation, specifically as they relate to deepwater well completions. Discussed are risk-mitigating, production and injection enhancing fluid stages, acid types, additives, stage options, diversion and placement practices, vessel options, flowback practices, and post-stimulation ramp-up and drawdown management. Supporting case examples are also presented.
