BZ26-6 Oilfield is a kind of deep metamorphic rock buried-hill volatile oilfield in Bohai Sea, China. Its early development plan restricted due to the simultaneous production oil and gas large sections reservoirs, unclear understanding formation fluid properties uncertainty gas-oil interface. Through theoretical research on phase recovery experimental analysis crude characteristics original for...

14C is an overwhelming background in low-background underground experiments, to the point where the observation of the all-important (pp) neutrinos from the Sun can not be observed in carbon-containing experiments. This paper shows that 14C purity can be improved by four orders of magnitude by a careful selection of the gas field. Two large reduction factors are at work: the low chemical affini...

To increase the oil production for the Tordis subsea oilfield located at the Norwegian Continental Shelf, a subsea separation and boosting station will be installed. Most of the water will be injected into a subsea reservoir instead of being transported up to the platform. Several challenges conserning process control need to be addressed before the implementation process, and dynamic simulatio...

Preformed particle gel (PPG, a kind of Super Absorbent Polymer) has been successfully applied to control conformance in around 2,000 wells in China oilfield. The paper summarizes: (1) why we proposed the method, (2) What are the properties of thermalstable PPG products, (3) where it has been used and how to select a good well candidate for a PPG treatment, (4) how to improve PPG treatment resul...

Bozhong A Oilfield is located in the northeast of Huanghekou Sag Bohai Bay Basin, and a complex fault block oilfield. The main oil bearing horizon lower Minghuazhen Member, belonging to shallow water delta sedimentation. For rolling exploration evaluation adjacent blocks, this paper uses mudstone smear method analyze accurately characterize lithological contact relationship between two walls fa...

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...
