Mexico has a wide range of oil fields; however, most of them are mature which makes it difficult to maintain oil production. Given this, advanced and improved recovery methods should be implemented to increase reserves and production of supplies in the country, an expert suggests.
As part of an unusual mortality event investigation, a team of scientists has discovered that dead bottlenose dolphins stranded in the northern Gulf of Mexico since the start of the Deepwater Horizon oil spill have lung and adrenal lesions consistent with petroleum product exposure.
Gas and oil seeps have been part of religious and cultural practices for thousands of years. Seeps from which gas and oil escape were formative to many ancient cultures and societies. They gave rise to legends surrounding the Delphi Oracle, Chimaera fires and “eternal flames” that were central to ancient religious practices – from Indonesia and Iran to Italy and Azerbaijan.
Experts argue for further in-depth assessments of the impacts of dispersants on microorganisms to guide their use in response to future oil spills. Chemical dispersants are widely used in emergency responses to oil spills in marine environments as a means of stimulating microbial degradation of oil. After the Deepwater Horizon spill in 2010, dispersants were applied to the sea surface and deep waters of the Gulf of Mexico, the latter of which was unprecedented. Dispersants were used as a first line of defense even though little is known about how they affect microbial communities or the biodegradation activities they are intended to spur.
A method of using bacteria to help test for the presence of a wide array of pollutants has been developed by researchers. The scientists say that their method may potentially be used for everything from well water testing to seaside construction purposes.
A single oil spill can release 30,000 tons of oil into the ocean if two vessels collide. In grounding the high weight can lead to oil disaster, in the Baltic Sea up to 120,000 tons. This estimate does not include the new giant tankers.
