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 system calculates as many ...

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 most integration ...

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, although some ...

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 developing enough electric ...

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 materials should be ...

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 will bring cathodic ...

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 the caliper is ...
