Agreement that defines how any gas production imbalance in the system will be balanced out between the parties to the agreement

Modeling flow in fractured reservoirs is difficult. The challenge requires a software solution that supports tight integration between the static and dynamic reservoir modeling disciplines and provides a way to visualize and analyze many data types that may be direct or indirect indicators of fractures

Drilling mud permeated with bubbles of gas from downhole. The circulation of such mud can be severely impaired, thus seriously affecting drilling operations

Established by Iran, Russia and Qatar in 2001

The gas that accumulates in the upper portions of a reservoir where the pressure, temperature and fluid characteristics are conducive to free gas. The energy provided by the expansion of the gas cap provides the primary drive mechanism for oil recovery in such circumstances

Injecting specially engineered fluids under high pressure into the channels of a low permeability reservoir to “crack” the reservoir and improve the flow of oil.

Gas molecules (e.g. methane) trapped in water-ice “cages” in subsea deposits. Some scientists believe that methane gas will be a substantial source of energy
