| 发明名称 | Dry drilling fluid additives and methods relating thereto | ||
| 摘要 | Dry drilling fluid additives may include a dry mixture that comprises a clay stabilizing agent at about 76% to about 93% by weight of the dry mixture, a dispersant at about 3% to about 6% by weight of the dry mixture, and a surfactant at about 4% to about 18% by weight of the dry mixture. Such dry drilling fluid additives may be useful in methods and systems for drilling wellbore penetrating subterranean formations, especially deviated and highly-deviated wellbores. | ||

| 主权项 | 1. A method comprising: providing a dry mixture comprising a clay stabilizing agent at about 76% to about 93% by weight of the dry mixture, a dispersant at about 3% to about 6% by weight of the dry mixture, and a surfactant at about 4% to about 18% by weight of the dry mixture; mixing the dry mixture into an aqueous fluid, thereby producing a drilling fluid; and drilling at least a portion of a wellbore penetrating a subterranean formation with the drilling fluid. | ||
