Calculating control area and reserves of single well by triangulation method

Abstract

Abstract The arithmetic average method is a conventional method to calculate the geological reserves. However, it ignores the influence of heterogeneity in the block, especially the faults. The calculated single well controlled reserves are often quite different from the actual status, which can’t guide the development actions accurately. Therefore, it is necessary to introduce a more accurate calculation method. The triangular network method introduced in this article can improve the accuracy when calculating the control area of single well in fault area, support to evaluate the control reserves of single well, and reflect the changes of geological reserves near each well point accurately.
