The method applied to determine the optimal length of horizontal wells
A method, applied to determine the optimal length of a horizontal well (HW), based on the hydrodynamic modeling of a deposit site with surrounding wells is proposed. The accumulated net present value (NPV) is used as an optimization criterion. The difference between this method and the previous ones is the use of accumulated oil, water and water injection when calculating the net present value (NPV) providing to take into account the maximum number of determining factors. The performed calculations showed that a HW optimal length mainly depends on the geological specific features of the section of a deposit site where its drilling is planned, the state of development and other factors. That's why determination of the optimal length should be carried out individually for each HW. The proposed method has a direct practical significance and allows optimizing deposits development.
