Natural Vegetable Gum Drilling and Completion Fluids System for Industrial Control and Application
To simplify the operation for the oil and gas development for drill and complete the well in the petroleum industry, a natural vegetable gum drilling and completion fluids system is developed for the industrial control and application. As the system combines the advantage of the drilling fluid and completion fluid, it need not change the two different fluids during the operation, which is beneficial to the operation control. In addition, it can improve the implementation of the oil and gas exploration for industrial application. An extensive laboratory work for the high-temperature resistance capability of the natural vegetable gum drilling and completion fluids system is carried out, including the formulation study of the detailed system and the corresponding performance evaluation. In the system, with the basic formula of the natural vegetable gum drilling and completion fluids system, several new formulas beneficial to improve the high-temperature resistance capability of the system have been described. The corresponding laboratory analysis has demonstrated that the prosperities of the system, with the temperature resistance capability up to 305℉, are proper for the industrial application.
