- Company Profile:
A column of high-pressure nitrogen typically applied to a tubing string in preparation for drillstem testing or perforating operations in which the reservoir formation is to be opened to the tubing string. The nitrogen cushion allows a precise pressure differential to be applied before opening flow from the reservoir. Once flow begins, the nitrogen cushion pressure can be easily and safely bled down to flow formation fluids under a high degree of control.

A combination of a 6FF40 induction log with an electrode measurement such as a 16-in. (40-cm) short normal. In some cases other induction arrays, such as the 5FF27, may have been used. The use of both measurements in the induction electrical survey (IES) gave a qualitative indication of invasion.
Industry:Oil & gas
A common coating problem in which the protective coating detaches from the pipeline.
Industry:Oil & gas
A common measure for gas volume. Standard conditions are normally set at 60<sup>o</sup>F and 14. 7 psia, abbreviated MMscf.
Industry:Oil & gas
A common measure for volume of gas. Standard conditions are normally set at 60<sup>o</sup>F and 14. 7 psia, abbreviated Mscf/d.
Industry:Oil & gas
A common term for the infinite-acting radial flow regime. This portion of the pressure-transient response is between wellbore-dominated flow regimes in the early-time transient data and boundary-dominated flow regimes in the late-time transient data. This most common flow regime is the most central to pressure-transient analysis because its presence enables determination of permeability and skin.
Industry:Oil & gas
A common type of mineral deposit that is often found on wellbore tubulars and components as the saturation of produced water is affected by changing temperature and pressure conditions in the production conduit. Carbonate scales have a high dissolution rate in common oilfield acids and generally can be effectively removed using acid or chemical treatments. Scale inhibition techniques also may be used to prevent scale formation. In the majority of cases, scale prevention is simpler and more cost-effective than attempting a cure.
Industry:Oil & gas
A common unit of measurement for large production rates of natural gas, abbreviated Bcf/D.
Industry:Oil & gas
A common unit of measurement for the daily volume of crude oil produced by a well or from a field. The volume of a barrel is equivalent to 42 US gallons, abbreviated BOPD.
Industry:Oil & gas
A common unit of measurement for the volume of water produced each day by a well or in a field. The volume of a barrel is equivalent to 42 US gallons, abbreviated BWPD.
