Oilfield Review Winter 2014/2015: 26, no. 4. Copyright © 2015 Schlumberger. FMI is a mark of Schlumberger. Sediments undergo several modifications to become the source rocks, reservoirs and seals that generate and contain petroleum reserves. The changes that occur between deposition and lithification, collectively known as diagenesis, include the processes of compaction, cementation, dissolutio...

Numerical methods of permeation fluid mechanics for black oil (water, oil and gas)--three compound combination flooding (polymer, surface active agent and alkali) in porous media is discussed in this paper. A mechanics model of three-phase flow (water, oil and gas)--three compound combination flooding (the polymer, surface active agent and alkali) is presented firstly, then a numerical algorith...

To dispose of large volumes of oilfield-produced water, an environmentally friendly method that reuses advanced-softened, silica-rich, oilfield-produced water (ASOW) as feedwater was implemented via a 10-month pilot-scale test in oilfield. However, salt deposition detrimental to the efficiency and security of steam injection system was generated in superheated steam pipeline. To evaluate the me...

Distributed generation (DG) based on oilfield associated gas has the characteristics of dispersive and small capacity. According to load control type, DG is treated as PQ point in power flow calculation. A distribution network reconfiguration algorithm based on simulated annealing and immune is proposed in this paper. Boltzmann simulated annealing operator is used in selection operation, and me...

––The oily mud waste is one of the main wastes in oil field production process, which also stands as a critical negative factor that impedes the improvement of oilfield environment. The oily mud, which is rich in oil and black viscous compound in appearance, is the solid waste that comes along with the oilfield production. The oily mud mixture has huge amounts in magnitude, and it contains a ce...

Oil field assimilation needs a complex of facilities and service lines for oil recovery, transportation and refining. It includes wells, collection stations, pipelines, meters, separators, formation pressure maintenance equipment, roads and power lines. Oilfield assimilation depends on the geographical and climatic features of the field, such as the areas under existing buildings, areas taken u...

Research on the modeling of rock mechanics parameters is of great significance to the exploration of oil and gas. The use of logging data with the Kriging interpolation to study rock mechanics parameters has been proven to be effective in reservoir prediction and other oilfield applications and can provide additional data. However, there will sometimes be a great deviation due to the limited sa...

Novel thermophilic, anaerobic, Gram-positive, rod-shaped bacteria, strains SL9 and OCA1, were isolated from oilfields in France and Australia, respectively. Both strains, together with Thermoanaerobacter yonseiensis KB-1(T) (=DSM 13777(T)), Thermoanaerobacter tengcongensis MB4(T) (=DSM 15242(T)) and Carboxydibrachium pacificum JM(T) (=DSM 12653(T)), possessed genomic (DNA-DNA hybridization stud...

The selection of appropriate wells for hydraulic fracturing is one of the most important decisions faced by oilfield engineers. It has significant implications for the future development of an oilfield in terms of its productivity and economics. In this study, we developed a fuzzy model for well selection that combines the major objective criteria with the subjective judgments of decision maker...

22 Do natural resource windfalls increase the risk of armed conflict within a country? Yu-Hsiang Lei and Guy Michaels investigate the impact of giant oilfield discoveries on the likelihood of civil conflict.
