Extreme overbalance stimulations using TCP proppant carriers
- Marathon Oil Co., Houston, TX (United States)
- Canadian Perforators, Calgary, Alberta (Canada)
The tubing-conveyed perforating (TCP) system with proppant carrier releases proppant and other particulates at the moment of detonation and allows materials to be injected into the producing interval while overbalance pressure levels and injection rates are maximized. Materials released at detonation are designed to enhance near-wellbore conductivity by scouring and propping the formation. This article briefly describes the mechanics of the TCP/proppant carrier system, and then discusses field applications to date. Topics encompassed will be treatment designs in fluid--sensitive formations, stimulations near water, productivity comparisons to other techniques and recommended permeability ranges where the system has been successful. Finally, the article addresses efforts to optimize and improve the technology, including use of fast gauge data, tracer logs and a combination perforating gun/propellant sleeve system. The combination system is currently being field tested by Marathon and a group of service companies as a joint development project, and has potential to be the next major improvement in extreme overbalance stimulation technology.
