Industry Overview

Land Owner vs Mineral Owner

The United States is one of the few countries in which mineral rights actually matter. In most other jurisdictions, sovereign governments retain complete ownership of valuable sub-surface materials. Private or state-run exploration and extraction companies must ink long-term leases to exploit these reserves. Although property owners who live above exploited reserves may be compensated for their troubles, they're not entitled to receive payment for the actual minerals or energy stores beneath their landholdings.  Read more...

 

Well Equipment Costs

The recovery of oil from wells using pumpjack rods and metal tubing is costly, inefficient, and environmentally hazardous. The frequent repair and maintenance of pump jacks require the use of a workover rig; which can often be expensive, time consuming and dangerous to operate. In addition to these challenges, this system has the potential to leak fluid into the environment and is susceptible to corrosion.

In every instance we install the Ωmega Production System, we are able to do away with surface equipment such as the pumpjack, motor, concrete slab used for mounting the pumpjack as well as downhole equipment, rods, pump and tubing.  All that remains at the surface is our customized wellhead, electrical supply and flow line connection.  Read more...

 

Well Maintenance Costs

Mechanical failures are the cause of nearly one quarter of the abnormal production declines seen in stripper wells. These mechanical failures are most commonly the result of corrosion, often exacerbated by the build up of corrosive brine in wellbores or its movement through production equipment. Marginal well operators must react to corrosion-sourced mechanical failures, but typically do not follow a proactive methodology for identifying problem areas and selecting the appropriate corrosion mitigation alternative before the failure takes place. As a result, opportunities for reducing failure rates and increasing production are missed.  Read more...

 

CBM Well Costs

The coalbed methane industry has become an important source of natural gas production. Proper dewatering of coalbed methane (CBM) wells is the key to efficient gas production from these reservoirs.

Coalbeds are naturally fractured, low pressure, water saturated gas reservoirs. The mechanism by which gas is stored and produced in coalbed reservoirs is quite different from sandstone reservoirs. In a conventional sandstone reservoir, gas is stored in the pore space and flows through the pores into the fractures and/or the wellbore In a coal-seam reservoir, while some free gas may exist in the coal deposits, the majority of the gas is adsorbed on the surface of the coal matrix. To produce this gas, the reservoir pressure must be reduced so that the gas can be desorbed and released from the matrix into the fractures. The gas can then migrate through the fractures and coal cleat system and flow into the wellbore.

Initially the natural fractures of the coal are typically water saturated. This water has to be removed in order to achieve any significant gas production. Dewatering of the coal seam reduces the hydrostatic pressure of the reservoir, which allows the gas to be desorbed from the coal matrix. At the same time, lowering the water saturation level of the reservoir increases the relative permeability of gas, thereby permitting the desorbed gas to flow to the wellbore. The maximum gas production is achieved when the BHP is minimized.

A proper dewatering system is essential for the production of methane from most coalbeds.  Read more...
