... low permeability reservoir, the capillary pressure is very significant. In addition, researches have shown that the flow in low permeability media doesn't follow the Darcy's law and there is threshold pressure gradient occurring in the percolation. Therefore, the traditional method is no longer...

... and magnitude of parameters in analyzing fracture treatments is one of key steps to produce low permeability reservoirs in fields. Based on practical examples, fracture shape inversion technique of horizontal well fracturing was carried out by analyzing logging data, monitoring fracture data, and running 3-D...

... Abstract This paper presents a new percolation method that is power-law non-linear percolation pattern in low-permeability reservoirs. Well test interpretation model on power-law non-linear percolation pattern is given and the way how to solve those equations is provided. To analyze and compare...

... Abstract It is very difficult to develop the low permeability reservoir. Nowadays it faces serious challenging because of the decline of oil price. In the paper, based on a great amount of investigation, the main problems in developing low permeability reservoir with water flooding are pointed...

... benefit. The production and utilization of low permeability oil and gas resources was limited by the high input and the low output. Based on systematical analysis of reservoir characters, damage mechanism and flowing patterns of low permeability reservoirs, a suit of techniques was worked out to deal...

... Abstract Several key problems concerning refracturing in low permeability reservoirs have been studied, i.e. effectiveness of initial fractures, effects of water cut, reservoir pressure on post refrac performance and selection of candidate wells, optimization of fracture length, treatment...

... parameters are interdependent, each reflecting one aspect of their relationship to the residual oil. The other is the capillary "entrapping force" in the low permeability reservoir on the residual oil. It is indicated through theoretical calculation that the residual oil saturation rises up...
