چکیده

Abstract As an important unconventional resource, shale gas can alleviate energy shortage, and its efficient development ensures the long-term growth of oil gas. The prediction production levels estimated ultimate recovery with high accuracy is necessary for development. Conventional methods are widely applied in industry owing to their simplicity effectiveness; however, none them accurately predict results frac hits affected wells. In this work, a probability method based on numerical model reservoir has been formed. view impact productivity wells during reservoirs, embedded discrete fractured simulation reservoirs proposed simulate geological engineering parameter range before frac. And aiming at established reservoir, adopts ensemble smoother multiple data assimilation automatic history matching technology carry out process model. Based theory results, study analyses influence different distribution functions parameters calculation reserves, obtains expected curve reserves through combination calculation. Besides, effectiveness was verified by comparing other traditional predicted method.

A numerical method for solving nonlinear partial differential equations based on Sinc-Galerkin method

In this paper, we consider two dimensional nonlinear elliptic equations of the form $ -{rm div}(a(u,nabla u)) = f $. Then, in order to solve these equations on rectangular domains, we propose a numerical method based on Sinc-Galerkin method. Finally, the presented method is tested on some examples. Numerical results show the accuracy and reliability of the proposed method.

A Novel Acoustic Liquid Level Determination Method for Coal Seam Gas Wells Based on Autocorrelation Analysis

In coal seam gas (CSG) wells, water is periodically removed from the wellbore in order to keep the bottom-hole flowing pressure at low levels, facilitating the desorption of methane gas from the coal bed. In order to calculate gas flow rate and further optimize well performance, it is necessary to accurately monitor the liquid level in real-time. This paper presents a novel method based on auto...
