The largest ultra?deep (>7000 m) strike?slip fault?controlled oilfield was found in the tight Ordovician carbonates Tarim Basin. Because oil production wells Fuman Oilfield generally have bottom water, a reasonable design is of significant importance for extending water?free recovery period and improving recovery. However, there no economical effective quantitative method to determine capaci...

Computational Fluid Dynamics (CFD) is a mathematical tool capable of simulating a wide range of fluid flows. Integrated CFD software has been applied to study the flows in oilfield separators. The influence of inlets, internals, and outlets has been studied with CFD simulations. Of particular value has been the ability of CFD to simulate wave induced sloshing in vessels mounted on floating plat...

The draft genome sequence of Geobacillus sp. strain 1017, a thermophilic aerobic oil-oxidizing bacterium isolated from formation water of the Dagang high-temperature oilfield, China, is presented here. The genome comprised 3.6 Mbp, with the G + C content of 51.74%. The strain had a number of genes responsible for numerous metabolic and transport systems, exopolysaccharide biosynthesis, and deco...

A novel associative model was developed to predict petroleum well performance after remedial treatments. This application is of interest, particularly for non-uniform oilfields such as naturally fractured ones, and can be used in decision support systems for water control or candidate well selection. The model is based on the Gamma classifier, a supervised pattern recognition model for mining p...

Abstract The Gaoshangpu block of Jidong Oilfield is a hot for increasing production and storage in Oilfield. High-quality efficient drilling completion can shorten the operation time have huge economic social benefits. Aiming at problems large well depth, complex geological conditions, poor stratum drillability, low machinery efficiency, long cycle Oilfield, this paper optimizes its drill bits,...

A study was carried out and an analysis made of the features operation oilfield control center. The technical solutions for management power supply facilities oil field are considered

Abstract In oilfield, scaling caused by water injection is becoming increasingly serious blocking the gathering and transmission pipelines of oilfield resulting in a decline production great loss production. Oil gas leakage pipeline scaling, corrosion perforation has irreversible damage to surrounding environment. this paper, citric acid sodium pyrophosphate are used as main agents, hydrolytic ...

The relative permeability curve is an important basic data for the preparation and dynamic analysis of oilfield development ( adjustment ) schemes. Due to different types curves in water cut stages, there a large deviation prediction indexes ultra-high stage according early development. In order study change process, based on morphological characteristics 118 28 coring wells Xingbei area after ...
