US EPA announces nationwide plans to study fracking impacts
Department’s state presence could influence future federal & state regulation As a follow-up from Enhesa’s June 2011 Flash coverage on recent U.S. concerns over hydraulic fracturing (“fracking”), Enhesa would like to share additional developments on this issue that heighten the probability of more stringent federal and state regulation. Ongoing concerns raised by ...

The Middle East should think twice about fracking
Securing energy resources is critical for fuelling development, but deciding which types of energy to invest in will affect a country’s future in many ways — and not all are good when it comes to shale gas. Four countries in the Middle East and North Africa (MENA) — Egypt, Jordan, Saudi Arabia and Tunisia — are planning to extract shale gas, and one, Algeria, is said to ...

The Stats on Fracking: The Real Numbers of Hydraulic Fracturing
Hydraulic fracturing, sometimes referred to as “fracking,” is among the largest and most influential trends in the global energy sector today. By injecting highly pressurized fluid into underground formations containing oil and natural gas, hydraulic fracturing makes it possible to exploit fossil fuel reserves that were previously too expensive or too difficult to reach with more ...

The Future For Fracking
Summary -Fracking is an essential technology to meet growing global demand for oil and gas. -Fracking has become the "F" word, because it is very water-intensive, and has potential negative impacts on the environment. -The future of fracking will be constrained if adequate water is not available and if solutions for decontaminating wastewaters are not found. -Oil sands production faces the same ...

Generation using gas-fuelled engines in South Africa – an overview
Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, cogeneration and, even, trigeneration units to optimise energy utilisation in the fuel ...
