Pseudomonas aeruginosa DQ8, which was isolated from the crude oil polluted soil in the Daqing oilfield of China, can efficiently degrade diesel, crude oil, n-alkanes, and polycyclic aromatic hydrocarbons (PAHs). Here, we present a 6.8-Mb assembly of its genome sequence. We have annotated 23 coding sequences (CDSs) responsible for catabolism of n-alkanes and PAHs.

The structure of S Oilfield Bohai sea area in China is located the low uplift slope zone Dongwa Laibei Huanghekou depression. target interval oilfield belongs to Paleogene layered structural oil reservoir under influence igneous rocks. Due widespread development rocks, and diversity rock types, complex, lateral changes are intense. differences volcanic eruption intensity materials made masses o...

The oilfield water in the Upper Sandstone Member of the Zubair reservoir (Barriemian-Hauterivian) at Rumaila North Oil Field was investigated for the interpretation of salinity and geochemical evolution of brine compositions. The interaction of the oilfield water with reservoir rock resulted in a brine water derived from the marine water origin of partial mixing with meteoric water similar to t...

Several operations in the Exploration and Production (E&P) sector are event-driven in nature and are supported by specialized systems and applications. Narrow focus of applications results in application silos that restrict the information sharing across verticals, which is a critical requirement for coordinated cross-functional efforts. Effective response to events warrants due emphasis on an ...

The Bozhong oilfield (Hereinafter referred to as BZ oilfield) is a typical representative of complex fluvial reservoirs in the Bohai Sea, located southern with an average porosity 30.3% and permeability 643 × 10-3 μm2, belonging medium high reservoir, reservoir has good connectivity, underground crude oil viscosity 5 mPa·s. There are many plane fault blocks, longitudinal well section long, so o...

Recent developments in water-soluble hydrophobically associating polymers are examined with particular emphasis on their use for oilfield applications. These polymers have potential for use in EOR, acidizing, drilling fluids, completion fluids and profile modification. They have also been reported to selectively reduce water permeability in sandstones, and have been used as drag-reducing agents...

In the middle and late stage of oilfield exploration development, difficulties such as land acquisition on surface, high density underground well pattern development cost are serious. Dense cluster Wells mainly way to mode transformation quality efficiency improvement. Combined with practice dense in Dagang Oilfield, paper detailed analyzes faced by design drilling engineering, which including ...

In the process of oilfield development, water injection is a very important work content, and reservoir exploitation quality, efficiency, are closely related. Oilfield technology has been widely applied popularized, but in specific application, it will also have some influence on oilfield, such as causing oil layer blockage. The author focus application well injection, analyze related reasons f...
