The oil company holds the investment opportunity to develop a delineated oilfield. The investment plan must be presented until a specific date or the oilfield rights return to the government. The firm considers a set of mutually exclusive alternatives of scale to exploit the oilfield. Larger scale means faster exploitation – increasing the present value of revenues, but also higher investment c...

With the development of mobile technology, especially the development of 3G and mobile IP, the computational capacity of handsets is becoming more and more powerful, which provides a new method to solve the difficulties encountered in real time GIS accessing caused by the characteristics of mobility and remoteness of fieldwork in oilfield. On the basis of studying in-depth on the technologies o...

Wellbore instability is one of the major problems that hamper the drilling speed in Halfaya Oilfield. Comprehensive analysis of geological and engineering data indicates that Halfaya Oilfield features fractured shale in the Nahr Umr Formation. Complex accidents such as wellbore collapse and sticking emerged frequently in this formation. Tests and theoretical analysis revealed that wellbore inst...

The toxicity of the combination xylene and diesel at a 50:50 ratio on African catfish (Clarias gariepinus) was investigated using static bioassay for 96hrs. No significant difference (P>0.05) observed in Physicochemical parameters experimental water after exposure 24 hours among different concentration gradients controlled unit. Although there an increased variation along gradient 96hours. b...

In order to explore the resource utilization of expired traditional Chinese medicine, in this study, three medicines, LQC, BLG and HXZ were used evaluate their inhibition effects on clay expansion rate corrosion acid solution by weight loss method linear test. The results reveal that highest at 1000mg/L is 67.65% 3.0% HCl solution. Linear experiments show LQC have stronger effect when 1.2% them...

In petroleum chemistry, waxy oil from paraffins can cause operating problems for production. The chemical method is used to remove by using chemicals or additives prevent the wax problem. this study, performance of inhibitor are evaluated measurement pour-point reduction and deposition crude Mae Soon area, Fang oilfield. Wax determined cold finger technique. inhibitors, hexane, Poly(maleic anhy...

Based on statistical analysis on the situation of casing damage and water injection pressure in Pubei Oilfield, it shows that the main forms of casing damage in Pubei Oilfield are deformation and dislocation. Dip angle and faults have a significant impact on casing damage and casing damage is closely related to water injection pressure. Through laboratory simulating experiment and theoretical c...

Time variability of reservoir parameters in water flooding has an effect on oilfield development rules. Meanwhile, time variability of different reservoir macro-parameters has certain synergetic relationship with each other. Based on microscopic network simulation and reservoir numerical simulation, a new simulation method is presented, which can describe the influence of reservoir parameters' ...
