Petroleum Goodies: Absolute Permeability

Posted: 26 May 2011 10:00 AM PDT

Absolute Permeability: The way of measuring permeability, or capability to pass or transfer fluids through a rock, performed when a single fluid, or phase, exists in the rock. The expression most often used for permeability is k, that is calculated in units of darcies or millidarcies.

Compressor: An equipment which enhances the pressure of air or natural gas. A compressor typically uses positive displacement to compress the gas to larger pressures so the gas can easily pass into pipelines and other equipments. Commonly used in production facilities.Similar Posts:

Petroleum Goodies: Damaged Zone

Damaged Zone

Posted: 24 May 2011 10:00 AM PDT

Damaged Zone: The local area around the wellbore which has been impaired through the drilling activity, normally due to mud or cement-filtrate intrusion. Near-wellbore impairment can substantially impact efficiency and is generally simpler to avoid compared to fix.

Even though typically present, a lightly damaged area around the wellbore can be bypassed by perforation channels to generate connecting conduits from the wellbore to the undamaged reservoir zone.

More serious cases of damage may need a matrix-acidizing treatment to regenerate the natural permeability, or a hydraulic fracturing solution to generate a new high-conductivity flow direction to the reservoir. Generally used in perforating, well completions.
