cluster analysis
Oil & gas; Oilfield
Mathematical techniques for summarizing large amounts of multidimensional data into groups. The two most popular techniques are: hierarchical k-means. The hierarchical ...
numerical methods
Oil & gas; Oilfield
Mathematical methods that require iterative processing of data rather than applying deterministic equations. Some relationships can be solved only by numerical methods, including ...
autochthonous
Oil & gas; Oilfield
Materials, especially rock masses, that formed in their present location and have not been transported. Fault surfaces can separate indigenous rocks from allochthonous rocks, ...
galvanic anodes
Oil & gas; Oilfield
Materials used to provide cathodic protection. Galvanic anodes are made of metals such as zinc, magnesium or aluminum, which corrode more easily than the structure, thus ...
naturally occurring radioactive materials (NORM)
Oil & gas; Oilfield
Materials typically found in certain types of barium or strontium scales that may be deposited in the wellbore or production tubulars. Any attempt to remove and dispose of NORM ...
impressed current anodes
Oil & gas; Oilfield
Materials to provide cathodic protection. Impressed current anodes are relatively inert to corrosion and require an external power source to generate the electric current that ...
derivative logs
Oil & gas; Oilfield
Logs that have been calculated from other logs to find the rate at which a log is changing with depth. For example, the derivative caliper (rugosity) calculates the rate at which ...
