- An accurate fracture gradient value is one of the most important issues in oil and gas well design and drilling. The value of a fracture gradient is a critical parameter for determining the drilling mud weight and selecting the proper depths for setting the casing in the planning process of drilling operations. This paper proposed the new curve model of fracture gradient for the south-central Kazakhstan (central Asia) region based on the analysis of leak-off test and format integrity test results. Data from more than 400 tested wells were analysed and compared with the results of existing methods for predicting the fracture gradient and with the results from previous drilling projects in that region. By using the new curve model, the more precise values of fracture gradient are determined. Besides an improved fracture gradient model development and validation, the model’s analytical expressions are presented. The article’s most important results are determining the model’s values of fracture gradient and providing a more accurate calculation of mudweight, less mud losses, more precise evaluations of cementing operations, better selection of the casing setting depth and improved drilling safety.
