Petrotech Oil and Gas, Inc. (PTOG)

Starting in the late 1990's PTOG 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, they found that a N2-CO2 mixture was 2-3 times more efficient than CO2 in the recovery of stranded oil. Recently PTOG has 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.

PTOG has 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 their 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 PTOG's patented method and technology.

CO2 floods have been successful on the reefs in the US with rates as high as 1000 BOPD. PTOG's process will have a major impact on the recovery of stranded oil in U.S. basins. This statement is based on the fact that they have an unlimited source of gas and 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 PTOG 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.

The United States oil production is in a state of primary depletion where 98%+ of all wells are defined as stripper wells. Typically, oil reservoirs produce less than 20% of their Original Oil in Place (OOIP) through primary production techniques. The remaining 80%+ lies in a stranded state unless an Enhanced Oil Recovery technique is initiated. EOR history has shown that various EOR techniques can help with the recovery of 50% of the OOIP. Historically, EOR has been implemented in reservoirs that have progressed through their Primary and Secondary Production Phases (Water Flood). The common practice is to sweep fluid through a reservoir in a horizontal manner from an injector well to producing wells. The production response time in reservoirs using CO2, Nitrogen or a mixture is excellent, showing significant production increases in less than one year.

Currently, there are only 80 plus, Enhanced Oil Recovery Projects in the United States producing approximately 200,000 barrels of oil a day. Further development of EOR projects is expanding very gradually due to the shortage of pure CO2 from natural and industrial sources. Historically, EOR projects have the highest financial returns in the industry, even with the high development and infrastructure cost. Utilizing a new source of gas is critical to the expansion of EOR.

PTOG looks to be in a prime position to benefit on what is expected to be a booming U.S. oil industry in the near future!

The global oil market will be transformed over the next five years as faster-than-expected production growth in North America combines with a greater acceleration in demand than predicted among Asian and Africa countries, according to a new report from the International Energy Agency (IEA).

The US will become the world's largest oil producer within the next five years and the rise in production is "even steeper than previously expected", said Maria van der Hoeven, the executive director of the International Energy Agency.

As the U.S. looks to supply the growing global demand for oil PTOG and their cutting edge technology will be needed to maximize its domestic well production!
