GOHFER® software evaluation
Research output: Research › Master's Thesis
This thesis evaluates the potential of Bio Enhanced Energy Recovery (BEER®) technology application in the tight gas sandstone reservoir hydraulic fracturing job with the help of the 3D simulator GOHFER®. The fluid rheology is investigated and, furthermore, efficiency of the fluid and glass beads proppants application is evaluated and compared to the common commercially available products. Nowadays, there is a great demand for the new eco-friendly products that would be compatible with the environment, on the one hand, and would be efficient in terms of its technical application, on the other hand. The thesis consists of two parts: experiments and simulations. The experimental part of this work includes rheological tests performed for the BEER® fluid and sieve analysis performed for the glass beads. The simulation part consists of analyzing the reservoir properties, designing the treatment job, investigating the 3D fracture geometry and post-treatment production enhancement evaluation. In addition, the sensitivity analysis is performed in order to investigate the gross fracture length, the propped fracture cutoff length, conductivity and production rates behavior depending on different variables, such as proppant materials, job treatment size and slurry rates. The results obtained by the simulation indicate, that the proposed technology is indeed suitable for hydraulic fracturing treatment of the analyzed reservoir and that it provides good fracture geometry, as well as the production improvement. Moreover, it has been confirmed that GOHFER® allows to model a user defined fracturing fluid, as well as proppants. In addition, it has been proved that the software calculation algorithm is based on the rigorous studies of the hydraulic fracturing processes and therefore gives very accurate results.
