Aug 09, 2007· An under-balanced drilling fluid additive is disclosed which reduces reactive shale and/or clay swelling during under-balanced drilling operations, where the additive includes an effective amount of a choline salt. A method for under-balanced drilling is also disclosed including the step of circulating a drilling fluid including an effective amount of a choline salt to reduce reactive shale ...
Apr 26, 2017· Sand, barite, polymers, thermal-set resins, plastics, and cement slurries are all placed with this technique. The use of dump bailers for spotting materials that thermally depend on set times (such as polymers, resins, and cement slurries) has historically been limited to shallow depths because of temperature concerns; but modern polymer and ...
Frac Sand Testing - Basics of Frac Sand Testing. Frac sand needs to be very strong. Strength is found using the crush resistance test. The crush resistance test is used to determine a "K Value," which is the pressure at which 10% or more of the sand starts to break into fines.
would be likely to frac with existing drilling fluid density, and which need to be strengthened. For this application, a very clean fluid is used to keep the solids distribution constant. If the formation of concern is sand, then a blend of calcium carbonate and SURE-SEAL™ …
Jun 14, 2016· Under high pressure environments (7-10,000 psi) frac sand fails and starts to crush. However, the crushed proppant can help keep slipped fractures open. Trepess demonstrated that a prevailing "nanoDarcy environment" favours continuous use of frac sand …

Jun 12, 2018· Re-fracking is the practice of returning to older shale oil and gas wells that had been fracked in the recent past to capitalize on newer, more effective extraction technology. Re-fracking may be effective on especially tight deposits (e.g., where the shale or sand produces low yields) to expand their productivity and extend their life.
