Foam flooding (or injection of foam) is a common technology to enhance oil recovery. Although the effects of permeability on foam flooding were well studied in many laboratory experiments, little research has been focused on the specificity of low permeability. In this paper, a series of constant-quality nitrogen foam flow experiments were conducted to investigate the effects of permeability on...

A sequence of different Reservoir Engineering methods and tools in reservoir characterization and field development are presented in this paper. The real data of Jin Gas Field of L-Basin of Pakistan is used. The basic concept behind this work is to enlighten the importance of well test analysis in a broader way (i.e. reservoir characterization and field development) unlike to just determine the...

The quality of any reservoir is strongly controlled by diagenetic processes, especially those that are comprised mixed siliciclastic-carbonate sequences. An Eocene sequence forms reservoirs with diverse in the Hungarian Palaeogene Basin, which found within Pannonian Basin. Late transgression established extensive shallow-marine depositional environments controlling early processes. Drill cores ...

Carbon dioxide (CO2) dissolution is the secondary trapping mechanism enhancing long-term security of CO2 in confined geological formations. injected into a randomly multilayered formation will preferentially migrate along high permeability layers, increasing efficiency. In this study, sequential Gaussian simulation adopted to construct stratified saline formations, and two-phase flow based on M...

Inflow control devices (ICD), which prevent water breakthrough by controlling the inflow profile of a well, have been used successfully in many oilfields. This paper will introduce a new discovery and an unsuccessful example. Moreover, this paper investigates meticulously and thoroughly to find the application conditions of the new discovery. Based on permeability rush coefficient and permeabil...

Simultaneous capillary dominated displacement of the wetting and non-wetting phases are processes of interest in many disciplines including modeling of the penetration of polluting liquids in hydrology or the secondary migration in petroleum reservoir engineering. Percolation models and in particular invasion percolation is well suited to characterize the slow immiscible displaceme...

Pore structure is the key element of tight sandstone reservoir, which restricts accumulation and flow oil gas in reservoir. At present, reservoir pore focus difficulty unconventional exploration development research. The Chang 4 + 5 member Upper Triassic Yanchang Formation main for G area. there little research on its fractal characteristics, to some extent affects progress development. This pa...
