Oil and gas energy is one of the necessary sources for social development. In process oil development exploration, hydraulic fracturing technology plays a vital role. Hydraulic can not only stabilize production conventional fields, realize low-permeability reservoirs, help adjustment old but also increase special reservoirs tap potential fields. this paper, an electrical simulation experiment m...

developing countries that have almost oil reserves have no enough mega projects' management ability, technology and finance resources to manage and finish a mega project. host countries for achievement these technologies and resources have to cooperate with foreign and international companies.  different contractual frameworks are used in conjunction with obtaining these technologies and c...

C oilfield is a heavy oil field developed by horizontal wells and single sand body in Bohai oilfield. The edge bottom water of the reservoir active natural energy development mode adopted. comprehensive cut was 95.3%, which had entered stage high production. Some reservoirs were limited crude viscosity column height. Under condition existing well pattern, some reserves not produced or degree pr...

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...

Simulation models are commonly used as an aid to decision making for oilfield development and operations. Such models represent information uncertainty and alternate operational strategies and form a design space, which is used by engineers to explore different “what-if” scenarios. As the composition of the engineering team changes over the lifetime of the oilfield and new modeling requirements...

Isatin, an extract from Strobilanthes cusia (Nees) Kuntze, was the base for synthesizing derivatives that were screened for antibacterial activity against oilfield water-borne bacteria. The bacterial groups are sulfate reducing, iron and total. The derivatives were characterized by spectrums and they showed good to moderate activity against sulfate reducing bacteria.
