Software applications

The sector over the past several decades, as a result of demand for trustworthy predictions of reservoir efficiency. The improvement in electric computing equipment, and the significant improvement in methods of statistical analysis were two important factors in the accomplishments made in statistical models of reservoirs such models made important contributions for the enhanced petrol recovery.

Reservoir designs are used for appreciate and forecast reservoir performance. One of the most important activities during the process of growing and handling the petroleum reservoirs is definitely History matching process. The Matched unit are critical in making reliable future predictions possible, and offer an idea of the level of comprehension of the geological and water tank models. Based on available discipline production info, and difficulty of a reservoir, the History matching process is quite time consuming. To accomplish matched unit, some changes can be done on the geological and reservoir models, mainly in these attributes with higher doubt, for example , relative permeability figure, its distribution through the reservoir, and other parameters with few samples.

One of the aims of this job is to execute history complementing on the Zhaozhouqiao oil discipline specifically Zh86 Block applying Schlumberger’s simulation software Petrel-RE 2014. Background matching will be done based on trial and error simply by modifying several reservoir properties, end stage scaling through modeling and including the aquifer support in to the system. The very best history match was attained by modifying the critical water saturation (SWCR) in the program, modeling an aquifer support using Carter Tracy Aquifer model and by modifying the horizontal and vertical Permeabilities of the model. After the record match is definitely achieved two prediction approaches are designed and as opposed, where we did forward modeling to generate some confidence level in the reservoir model. Development indexes, drinking water cut, water production, oil production and oil charge of wells and the discipline as a whole had been forecasted. Benefits of the indexes were presented against some analyzed. The results described that Zh86 Block in Zhaozhouqiao petrol field continues to be very appealing in terms of development.

A great Uncertainty and sensitivity examination was performed on the tank model to analyze the impact selected reservoir houses have on the volume calculations and simulation results in the Zh86 Stop reservoir style. The impact of uncertainty in our Sw and contact positions on volume level calculations from this model is seen.

The effect of the grid resolution in placing lateral wells was also analyzed, a synthetic type of the Zh86 Block was built choosing the differing grid promises both laterally and top to bottom, and then homes were up-scaled to the models and a well-placed under an gabardina shale zone in every model to look for the optimum position. Using a style with a great grid image resolution enables you to put the well in the very best position in the reservoir model.
