Research on the modeling of rock mechanics parameters is of great significance to the exploration of oil and gas. The use of logging data with the Kriging interpolation to study rock mechanics parameters has been proven to be effective in reservoir prediction and other oilfield applications and can provide additional data. However, there will sometimes be a great deviation due to the limited sa...

Novel thermophilic, anaerobic, Gram-positive, rod-shaped bacteria, strains SL9 and OCA1, were isolated from oilfields in France and Australia, respectively. Both strains, together with Thermoanaerobacter yonseiensis KB-1(T) (=DSM 13777(T)), Thermoanaerobacter tengcongensis MB4(T) (=DSM 15242(T)) and Carboxydibrachium pacificum JM(T) (=DSM 12653(T)), possessed genomic (DNA-DNA hybridization stud...

The selection of appropriate wells for hydraulic fracturing is one of the most important decisions faced by oilfield engineers. It has significant implications for the future development of an oilfield in terms of its productivity and economics. In this study, we developed a fuzzy model for well selection that combines the major objective criteria with the subjective judgments of decision maker...

22 Do natural resource windfalls increase the risk of armed conflict within a country? Yu-Hsiang Lei and Guy Michaels investigate the impact of giant oilfield discoveries on the likelihood of civil conflict.

The selection of well pattern system is not only the key content in process oilfield development, but also core problem design development. It basis for effective utilization tight reservoir technology. Through scientific analysis geological structure and dynamic characteristics Yang H oilfield, can be reasonably optimized development Chinese vigorous. Starting from oil gas field this paper ana...

After more than ten years of water injection development, the cut in main block oilfield B has increased rapidly and production decreased significantly. In view rapid rise comprehensive current oilfield, it is necessary to carry out research on development law reasonable boundary various adjustment indexes, so as clarify different stages The status index change under oil rates provide an accura...

The phenomenon of the cementing annulus micro clearance gas channeling directly influences cement job quality and oilfield production, so accurately describing the flow rule of cementing annulus micro clearance gas channeling is the core and "bottleneck" problem of controlling gas channeling effectively. From the perspective of the micro particle motion and based on the lattice Boltzmann method...

It is the important technology to take the optimum control of automatic drilling in the course of oilfield drilling in accordance with actual situation. Due to the complexity of drilling process and the non-linear relationship between input and output of drilling system; it’s difficult to acquire satisfied results to adopt general control method. This article presents a new control method which...

A modelling effort was made to try to predict the life of downhole tubes or casings, synthetically considering the effect of service influencing factors on corrosion rate. Based on the discussed corrosion mechanism and corrosion processes of downhole tubes, a mathematic model was established. For downhole tubes, the influencing factors are environmental parameters and stress, which vary with se...

Consider an undeveloped oilfield with uncertainty about the size and quality of its reserves. There are some alternatives to invest in information to reduce the risk and to reveal some characteristics of the reserve. This paper presents an evolutionary real options model of optimization under uncertainty with genetic algorithms and Monte Carlo simulation, to select the best alternative of inves...
