one of the mostly used enhanced oil recovery methods is the injection of water or gas under pressure to maintain or reverse the declining pressure in a reservoir. several parameters should be optimized in a fluid injection process. the usual optimizing methods evaluate several scenarios to find the best solution. since it is required to run the reservoir simulator hundreds of times, the process...

background: post-operative nausea and vomiting (ponv) following surgical operations requiring general anesthesia are common and distressing. the incidence of ponv may be as high as 70% during the first 24 hrs of tonsillectomy.   objective: this study determines the effects of intraoperative well-hydration on postoperative nausea and vomiting.   methods: 90 asa i patients with age of 6-12 years ...

The importance of the choice well exploitation methods is analyzed. Mechanical applicable in carbonate reservoirs are discussed. To maintain efficiency field development, it important to productivity wells at planned level throughout entire production period by increasing their productivity. Productivity increase, skin effect reduction achieved with help acid treatment, main principle which roc...

A gas kick simulation model for deep-water horizontal well with diesel-based drilling fluid is presented in this paper. This model is mainly based on the mass, momentum, and energy conservation equations. The unique aspect of this model is the fluid-gas coupling and the change of mud properties after the gas influx from the formation. The simulation results show that the gas in an annulus disso...

A proper understanding of reservoir fluid phase behavior is the first crucial step in the development and production of an oil/gas field. This paper addresses the challenges and errors associated with the fluid sampling that may arise before, during and after the sampling operation. For this aim, DST and PVT data of exploration and production wells of a supergiant offshore gas condensate reserv...
