Oil well stimulation, usually done with hot solutions of hydrochloric acid, may induce severe corrosion attack on production tubing, downhole tools and casing. Inorganic, organic and combinations of acids along with surfactants are used in a variety of well stimulation treatments. To reduce the aggressive attack of the acid on tubing and casing materials (N80 steel), inhibitors are added to the...

All oil and gas pipeline systems are run by human operators (called controllers) who use computer-based workstations in control rooms to "control" pipelines. Several human factor elements could contribute to the lack of controller success in preventing or mitigating pipeline accidents/incidents. These elements exist in both the work environment and also in the computer system design/operation (...

Microbiologically Influenced Corrosion (MIC) is becoming increasingly important, especially to the oil and gas industry as more and more reservoirs are soured due to increased practice of water flooding and pipelines are aging (some even beyond their anticipated life expectancies). Despite the fact that MIC research has been going on for several decades, there is much confusion in the MIC liter...

The extraction of hydrocarbons from shale formations using horizontal drilling with high volume hydraulic fracturing (unconventional shale gas and tight oil extraction), while derived from methods that have been used for decades, is a relatively new innovation that was introduced first in the United States and has more recently spread worldwide. Although this has led to the availability of new ...

The Russian invasion of Ukraine has brought a stream reports about the country's energy exports. Here are basic facts. Russia ranks second in extraction both crude oil (behind United States and ahead Saudi Arabia) natural gas Iran), it is sixth-largest producer coal Australia South Africa). Before war, exported 55 percent its fossil-fuel output, mostly to European Union. EU bought 85 that shipp...

Future exploitation scheme of an oil reservoir in each cycle within its production life depends on the profitability of the current extraction scenario compared with predicted recoveries that acquire with applying other available methods. In fractured reservoirs appropriate time to pass from the gas injection process into chemical enhanced oil recovery (EOR) firmly depends on the oil extraction...

In order to control the corrosion in pipelines, it is important to understand the underlying corrosion mechanisms and predict ion of it’s initiation and means of mitigation. This paper reviews the electrochemistry of corrosion, it’s kinetics and thermodynamic nature, with respect to CO2 and H2S effects in propagating corrosion in oil and gas pipeline system. The phenomenon of polarization and i...

Rapid population increase coupled with urbanization and industrialization has resulted in shortages of water in the Middle East. This situation is further exacerbated by global climate change due to greenhouse gas emissions. Recent research advocates that solutions to the global water security and scarcity crisis must involve water-energy nexus approaches. This means adopting policies and strat...
