PURPOSE To report the results of a two-step operation for treating retinal detachments caused by macular holes in high-myopic patients. METHODS In the first part of the operation, pars plana vitrectomy, air-fluid exchange, and silicone oil injection were performed. At 4-6 months after the first operation, the second part of the operation was performed. This involved silicone oil removal and i...

S urfing on the wings of time, days turned into weeks. Weeks turned into months. And, I found myself at a point to write you again—three months after the first issue of The IJOEM. Since then, many things happened: the Journal was welcomed by various healthcare professionals so that its Web site (www.theijoem.com and www. theijoem.org), received more than 60 000 hits almost three weeks after it ...

A parallel reservoir simulator has been developed, which is designed for large-scale black oil simulations. It handles three phases, including water, oil and gas, and three components, including water, oil and gas. This simulator can calculate traditional reservoir models and naturally fractured models. Various well operations are supported, such as water flooding, gas flooding and polymer floo...

The accurate prediction of wellbore temperature distribution helps to accurately estimate well pressure profile and bottom-hole pressure (BHP) which is important in the under-balanced drilling (UBD) operation. In this paper effect of temperature variation due to heat transfer of drilling fluid with the formation and also oil and gas production from the reservoir into the annulus in under-balanc...

The rapid development of global economy has leaded to climate change issues. greenhouse gases including carbon dioxide have driven the issues and become one concerns confronting human society. An offshore survey project that carried out by a service provider company in oil gas industry was chosen for footprint estimation during project’s operation this study. major objective study is calculate ...

As part of an overall strategy to lower its IT costs, an oil and gas company considered deploying its data base management system within a client/server environment, thus cutting both hardware expenditures and software licensing fees. The organization was skeptical, however, of the network's ability to support 150 concurrent users at an acceptable response rate. Long transaction times would red...

due to easy availability of cheaper raw material and increase in new applications, the use of polyolefins in variousindustries is becoming a major priority. the middle east region, on account of its vast oil and gas reserves has,in the last decade or so, been developing many new petrochemical complexes with their expansion into colossalpolyolefin production capacities. the predictions are that ...

surge is one of the two destructive factors in compressors. surge is the stream instability phenomenon in compressor that imposes severe damages to the compressors. nowadays, suppressingsurge phenomenon is one of the most important issues in oil and gas industries, especially when flow reduction or gas reflux is considered. according to moore-greitzer compressor model, this paper designs an act...
