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...

Microscopic flow in fractured porous media is a typical problem for the exploitation of tight reservoirs. The rapid-flow in the fractured porous-media is of great significance to efficient and continuous oil/gas exploitation. The fractures are expected to enhance flow conductivity and mass transfer between matrix and fractures, and to improve oil displacement during water flooding. However, the...

The energy demand in our modern society is continuously rising, which clearly shows that fossil fuels will for many decades still play an important role – oil and natural gas are important energy resources in this picture. Nevertheless, oil and natural gas reserves are limited, and it is therefore a prioritized task to produce more oil and gas from existing wells and reservoirs for better explo...

BACKGROUND Since 1972, oil companies have extracted more than 2 billion barrels of crude oil from the Ecuadorian Amazon, releasing billions of gallons of untreated wastes and oil directly into the environment. This study aimed to determine if there was any difference in overall and specific cancer incidence rates between populations living in proximity to oil fields and those who live in areas ...

These comments are respectfully submitted both as to the Horizontal Merger Guidelines ("HMG") generally, and also to questions 1-10., 12-15. They show that as a litigation matter the current HMG must be replaced because they are dependent on the PNB presumption, which will be overruled under the Supreme Court's GTE Sylvania and later presumption cases, and that new merger guidelines (and antitr...
