- Company Profile:
Natural gas that contains a few or no liquefiable liquid hydrocarbons. Lean gas is also called dry gas.
Industry:Oil & gas
Natural gas that does not contain hydrogen sulfide (H<sub>2</sub>S) or significant quantities of carbon dioxide (CO<sub>2</sub>).
Industry:Oil & gas
Natural gas injected into a formation to maintain or restore reservoir pressure. Other reasons for gas injection are gas-lift operations, cycling in gas-condensate reservoirs or storing gas.
Industry:Oil & gas
Natural gas containing heavier hydrocarbons than a lean gas. Its liquid content adds important economic value to developments containing this type of fluid.
Industry:Oil & gas
Movement applied to the casing string during the cementing operation to help in removal of drilling fluid and efficient placement of the cement slurry.
Industry:Oil & gas
Natural forces in the reservoir that displace hydrocarbons out of the reservoir into the wellbore and up to surface. <br><br>Reservoir-drive mechanisms include gasdrive (gas cap or solution gasdrive), waterdrive (bottomwater drive or edgewater drive), combination drive, and gravity drainage. Waterdrive is the most efficient drive mechanism, followed by gasdrive and gravity drainage. <br><br>Reservoir-drive mechanisms are also called natural drives.
Industry:Oil & gas
Models of reservoirs built using indicator (nonparametric) methods.
Industry:Oil & gas
Measurements made by measurements-while-drilling (MWD) tools subsequent to the initial bit run. MWD logs are recorded while drilling the well. However, these tools can also record logs at later times when the drillstring is in the hole. This may be while pulling out after drilling, or on a subsequent bit run or circulating trip. The latter is also known as logging while tripping.
Industry:Oil & gas
Mechanical or electronic devices for measuring various properties in the well such as pressure, fluid flow rate from each branch of a multilateral well, temperature, vibration, composition, fluid flow regime, and fluid holdup. These devices can be permanent; in this case, they are left in place for months or even years.
