Frac Hit Mitigation

Combat Frac Hit effects and increase production with nanoActiv®

THE PROBLEM

Frac Hits are a growing problem in the industry (see attached Society of Petroleum Engineers (SPE) paper – “Fracture Driven Interactions: Frac Hit Risk Reduction, Case Damage Potential, and Real Time Warning Signs.”) As infill drilling occurs, wells communicate, robbing pressure and significantly reducing the production of the parent well. As production from the parent well decreases (30% to 70%), the value of the well decreases, ultimately lowering the reserves booked for the well. On a larger scale if a company has 100 parent wells valued at $10 million each ($1 billion Total Value), the company could be facing a $300 million to $700 million write down as infill drilling occurs.

THE SOLUTION

To mitigate the effects of Frac Hits, nanoActiv® is deployed into the initial well during the re-pressurization process. nanoActiv® HRT or EFT is injected as pills or intermixed with a total volume of injected fluid. While the added fluid provides the benefits of a temporary high-stress barrier near the initial well, the nanoparticles provide the benefit of significant interfacial tension (IFT) reduction, as well as wettability modification near the well-bore to create a much more favorable fluid-flow environment. Consequently, not only are fracture interactions mitigated in the parent well, more hydrocarbons are also produced.

Eagleford 1 well was a Frac Hit Protection (FHP) treatment performed in January 2019. The well was drilled in 2015 with an initial production rate of 780 Bopd of oil. By 2019, 30 days prior to treatment, the well was producing an average of 50 Bopd of oil. Post-treatment, the well increased oil production to an average of 100 Bopd for 150 days. ~500 days post-treatment, the to-date incremental recovered volume is approximately 19,000 BOE. Treatment payback for the operator was approximately 30 days.

Payback: 30 Days
Incremental BOE: 19,000

Pre-Treatment Production

  • BOPD: 29
  • MCFD: 89

Post-Treatment Production

  • BOPD: 46
  • MCFD: 119

Current Production

  • BOPD: 45
  • MCFD: 20

Eagleford Frac Hit Protection (FHP) 2 was a treatment performed in May 2019. The well was drilled in 2014 with an initial production rate of 140 Bopd of oil and 430 Mcfd of gas. By 2019, 30 days prior to treatment, the well had fallen to an average of 30 Bopd and 90 Mcfd. Post-treatment, the well increased production to an average of 90 Bopd and 220 Mcfd for 150 days. ~360 days post-treatment, the to-date incremental recovered volume is approximately 21,000 BOE. Treatment payback for the operator was approximately 60 days.

Eagleford Frac Hit Protection (FHP) 3 was a treatment performed in May 2019. The well was drilled in 2014 with an initial production rate of 280 Bopd of oil and 850 Mcfd of gas. By 2019, 30 days prior to treatment, the well had fallen to an average of 15 Bopd and 60 Mcfd. Post-treatment, the well increased production to an average of 45 Bopd and 140 Mcfd for 150 days. ~360 days post-treatment, the to-date incremental recovered volume is approximately 11,500 BOE. Treatment payback for the operator was approximately 90 days.
