Petrotech Oil & Gas, Inc. (PTOG) 股价，以美元计价

Petrotech Oil and Gas,Inc. uses multiple patent technologies for Enhanced Oil Recovery. We will use this patented technology with other proven EOR technology currently used in the industry. Throughout the United States there are primary depleted oil reservoirs representing billions of barrels of oil that lend themselves to the use and exploitation of Enhanced Oil Recovery and Petrotech Oil and Gas,Inc. proven patented technology. Without EOR technology, these reservoirs will produce only about 20% of their Original Oil in Place. Gas injection EOR is a proven method that has been in use over the last 50 years in the oil fields of West Texas, Kansas, Oklahoma, Michigan, Wyoming and Oklahoma. Starting in the late 1990's we started researching various EOR methods and sources of gases and mixtures of gases to find an alternative gas to pure CO2 for EOR. In doing so, we found that a N2-CO2 mixture was 2-3 times more efficient than CO2 in the recovery of stranded oil. Recently we have been introduced to a patented exhaust unit that was more efficient than regular CO2. A new prototype of that equipment was then built for injection purposes; and is in the process of being further developed for commercial use. We have analyzed the different types of oil producing reservoirs in most of the major geological basins in the United States and have determined that the use of our process and method will enhanced the recovery of stranded oil reserves in these areas that otherwise may never be produced. The pinnacle reefs, other reefs in Texas make excellent reservoirs for EOR because they are compact, have consistent reservoir properties, thick pay columns, and are overlain by an impermeable cap seal. However other formations have responded favorably as well. These reservoirs represent over 300 million barrels of recoverable stranded oil using our patented method and technology. CO2 floods have been successful on the reefs in the US with rates as high as 1000 BOPD. Our process will have a major impact on the recovery of stranded oil in U.S. basins. This statement is based on the fact that we have an unlimited source of gas and we do not need an expensive infrastructure to transport the gas. Plus the fact that it is proven that a mixture of CO2 and N2 is more efficient than CO2 in some trials. The cost and recovery of a project will be dependent on size of structure and depth; the cost will range depending on type of formation and type of treatment design. Hopefully, per project we will capture an additional 20% to 40% of oil in place. Attempting to do this in a period of 5 years as opposed to the original 20% of oil that has already been produced; which may have taken ten to twenty years. Each successful project is estimated to have a six to twelve month payout.
