Abstract
Gas resources play a vital role in nowadays energy supply. It is providing 24 percent of all energy used in our diverse energy portfolio and it is important to recover as much gas as possible.
Water rising through fracture networks is one of main issues in naturally fractured gas reservoirs that causes gas trapping in matrix blocks and water production and subsequent recovery reduction. From Economic point of view it imposes high operating expenses, environmental risks, and productivity reduction.
Although numerical simulations can address relatively complex water rising problem, they usually are time consuming, and encounter difficulties in computational efficiency. A fast and appropriate decision making method is required to provide an immediate action to manage reservoir depletion where water rising is a serious challenge. This study introduces a fast approach to investigate the efficiency of common production strategies for managing depletion of naturally fractured carbonate reservoir when it has water rising issue through fracture networks.
