The thermophilic Geobacillus sp. strain FW23 was isolated from the Mehsana oil wells in Gujrat, India, during a screening for oil-degrading bacteria. Here, we report the draft genome sequence of Geobacillus sp. FW23, which may help reveal the genomic differences between this strain and the earlier reported species of the genus Geobacillus.

This paper presents the definition and implementation of a CORBA-based system for the distributed monitoring of automated oil wells located in on-shore petroleum fields. Conducted by the automation of industrial processes in the oil and gas area, the development of computational distributed systems, based on emerging middleware technologies and designed to monitor and actuate in such particular...

The knowledge and the forecast of the parameters which rule the downflow models in oil extraction and transport are today of paramount importance. In particular the extracted oil is mixed with water and gas in rates which differ not only from different wells, but also on the same well during its life. The main problems involved with the measurement of the flow rates are : well exhaustion, criti...

In this paper, Steam Assisted Gravity Drainage (SAGD) is introduced and its advantages over ordinary steam injection is demonstrated. A simple simulation model is built and three scenarios of natural production, ordinary steam injection, and SAGD are compared in terms of their cumulative oil production and cumulative oil steam ratio. The results show that SAGD can significantly enhance oil prod...

Gas-lifted oil wells are susceptible to failure through malfunction of gas lift valves (GLV). One failure mode occurs when the GLV check valve fails and product passes into the well annulus, potentially reaching the wellhead. This is a growing concern as offshore wells are drilled thousands of meters below the ocean floor in extreme temperature and pressure conditions and repair and monitoring ...

lithofacies identification can provide qualitative information about rocks. it can also explain rock textures which are importantcomponents for hydrocarbon reservoir description sarvak formation is an important reservoir which is being studied in the marun oilfield, in the dezful embayment (zagros basin). this study establishes quantitative relationships between digital well logs data androutin...

Millions of barrels of crude oil gushed freely from these wells, creating oil lakes in low-lying areas of the desert. Lakes were formed at more than 500 different locations, covering a total area initially estimated at 49 km. While the Kuwait Oil Company (KOC) has recovered 22.5 million barrels of the spilled crude; the remaining amount, is considered unrecoverable by standard methods. An estim...

A mathematical model has been developed to predict the temperature distribution in wellbores either offshore or inshore. It is incorporated the different activities encountered during drilling operations. Furthermore, the effect of drill collar and casings and bit rotating in a well during completion has been considered. The two dimensional approach is presented in the form of a computer progra...

Energy extraction within forest habitat is increasing at a rapid rate throughout eastern North America from the combined presence of conventional oil and gas, shale gas, and wind energy. We examined the effects of conventional oil and gas development on forest habitat including amounts of core and edge forest, the abundance of songbird species and guilds, species diversity, and community simila...
