Harness Oil and Gas Big Data with Analytics: Optimize Exploration and Production with Data Driven Models

Glossary

ADW

Analytical data warehouse customized to store those parameters deemed critical for subsequent advanced analytical methodologies.

ANN

In computer science and related fields, artificial neural networks are computational models inspired by animals’ central nervous systems (in particular the brain) that are capable of machine learning and pattern recognition. They are usually presented as systems of interconnected “neurons” that can compute values from inputs by feeding information through the network.

ANOVA

Analysis of variance is a collection of statistical models used to analyze the differences between group means and their associated procedures (such as “variation” among and between groups).

AVO

Variation in seismic reflection amplitude with change in distance between shot point and receiver that indicates differences in lithology and fluid content in rocks above and below the reflector. AVO analysis is a technique by which geophysicists attempt to determine thickness, porosity, density, velocity, lithology, and fluid content of rocks.

BHA

A bottom hole assembly is a component of a drilling rig. It is the lower part of the drill string, extending from the bit to the drill pipe. The assembly can consist of drill collars, subs such as stabilizers, reamers, shocks, hole-openers, and the bit sub and bit.

BHP

The pressure, usually measured in pounds per square inch (psi), at the bottom of the hole. This pressure may be calculated in a static, fluid-filled wellbore ...
