Why Wheeler?

Wheeler Resource Recovery's focus is on secondary oil recovery in proven oil fields. The bulk of the oil in a field is extracted in this second phase of development at a lower cost and far less risk than primary recovery.


This first phase of recovery involves the majority of risk and cost due to the learning curve required to find and produce oil from a field. Depth and thickness of oil bearing formations, oil content and flow characteristics are learned at the high cost of drilling wells. Production from this phase of development is dependent on the inherent natural pressure in the formation to push oil to the well bore. From the commencement of production, the natural pressure in the formation declines and production diminishes. As this pressure diminishes, an oil production decline curve sets in. Primary recovery can generally recover up to 30% of the oil in place before the pressure has been exhausted. These primary drilling programs are readily available in the market.


The second phase of field development begins by an evaluation, accessing the public records of the results from the primary drillers. Depth of formations, oil content and flow rates are now learned through the examination of these records at no cost to the project. By injecting water into these proven oil bearing formations, a water flood project artificially re-pressures the formation and sweeps up to 50% of the original oil in place to the production wells. This artificial induction of pressure alters the dynamic of the decline curve which rendered the primary recovery operations inoperative.

A five spot pattern is used to create this effect. A production well is drilled in the center of a square, with an injection well on each corner. As water is injected into the four surrounding corner wells, it pushes the oil to the production well in the center. This is an engineering exercise with results calculated by reservoir analysis from known data. Contrasted with primary drilling, which pays for the discovery of this data, successful water floods are lower risk, lower cost, and generally recover far more cumulative oil. Their production duration is controlled by injected pressure and the decline curve dynamic is offset.

Water flood projects are generally done in house by publicly traded companies and are seldom available to non-industry investors. They involve far less risk because they capitalize on the lessons learned from the initial primary drilling projects. Additionally a water flood project must have control of an entire field to make the technology effective and requires whole field operational experience and expertise. As such they are generally unavailable from a smaller operator.
