The product development process is characterized by accelerating cycles and increasing customer demands for a wide range of variants. In addition, it very knowledge-intensive the reuse knowledge in generation engineering. Developing new products based on existing references, e.g. about design parameters or manufacturing technologies, requires effective efficient transfer knowledge. transfer, pe...

Abstract For gas reservoirs with poor physical properties, the implementation of a single well multi-layer combined production is an effective means to achieve efficient development. However, because differences in geological conditions vast majority reservoirs, dynamic characteristics wells will be complex under mining mode, and inevitable interlayer interference process affect development eff...

 Understanding the flow behaviour in a gas well is crucial for future production strategies, obtaining bottomhole conditions from wellhead production data, analyzing production data and estimating reservoir properties. In this work, the pressure profile and flow regime are studied on four wells of a multi-well, multi-layer gas-condensate reservoir, producing at high rate. The wells are deviate...

the method of entropy production minimization for finding energy efficient paths of operation of process equipment is first presented using an instructive example with optimal control theory. with refer-ence to the earlier investigations, the researchers present some design rules that relate to the designs’ en-tropy production. minimum entropy production is not obtained in special cases, not ge...

Abstract Volume transformation technology has become a key for developing low-permeability/tight oil and gas reservoirs. Evaluating the post-fracturing effect is very important development plan formulation fracturing evaluation. In this paper, vicinity of main fracture divided into zone secondary zone. The with infinite conductivity branch increased permeability are used to describe area. Based...

Abstract Stimulation of unconventional tight oil formations via horizontal wells has seen increasing cases fracturing infill in recent years. The effectiveness such a strategy is mainly dependent on the proper characterization stress evolution and an accurate forecast subsequent fracture propagation region neighboring after considering production performance injection schemes parent wells. In t...
