The increasing activities in tight reservoir exploitation through fractured wells have attracted
interests of pressure-transient analysis (PTA) for well-performance evaluation. The …

Although technical advances in hydraulically fracturing and drilling enable commercial
production from tight reservoirs, oil/gas recovery remains at a low level. Due to the technical …

以大庆油田L 致密油藏为例, 评价了L 致密油藏的压裂改造效果; 通过现代产量递减分析和试井
分析, 总结了生产动态规律; 论证了水平井准天然能量, 注水吞吐, 注CO 2 吞吐开发效果 …

It is well known that waterflooding will create fractures. The created fractures are divided into
hydraulic fractures (artificial fractures with proppant) and induced fractures (formed during …

Nowadays, production performance evaluation of a multifractured horizontal well (MFHW)
has attracted great attention. This paper presents a mathematical model of an MFHW with …

The liquid production and water injection profiles are extremely important in understanding
the well and reservoir characteristics of horizontal wells. However, only several wells may be …

Field data indicate production profile along horizontal wells is nonuniform. This paper
develops an analytical model of multisegment horizontal wells (MSHWs) to estimate rate …

It is observed that production rates decline quickly and water-cut rises to 90% only after two
or three years' production for many multifractured horizontal wells (MFHWs) in China …

Numerical simulation and prediction studies on horizontal well performances in gas
reservoir are foundation for optimizing horizontal well completion process. To gain more …

The severe decline of oil production has been observed in many multi-fractured horizontal
wells (MFHW) within only one or two years. It is thus essential to determine production rate …
