Geostatistics and Data Analysis Quiz

A property of semivariogram models. Any linear combination of admissible models with positive coefficients can be nested or added together.

• Additivity

• Stationarity

• Linearity

• Permissibility

A series of techniques that use geostatistical methods to determine fluid and contaminant flow in the subsurface.

• Seismic Inversion

• Advective Transport Modeling

• Flow Assurance

• Stochastic Modeling

An example used for comparison. In oil and gas exploration, geoscientists and engineers compare new prospects and fields with fields and surface exposures thought to be similar in depositional environment and reservoir character to guide predictions.

• Outcrop

• Reservoir Simulation

• Analog

• Type Curve

A mathematical method of finding a central value for a group of data. It is most often referred to as the average but also as the mean.

• Mode

• Median

• Interquartile Range

• Arithmetic Mean

The study of ideas that enable computers to do the things that make people seem intelligent.

• Artificial Intelligence

• Robotics

• Expert Systems

• Cognitive Computing

The angle that characterizes a direction or vector relative to a reference direction (usually True North) on a horizontal plane.

• Inclination

• Azimuth

• Dip

• Orientation

An inference or deduction made using Bayes' theorem

• Likelihood

• Conditional Logic

• Bayesian Inference

• Posterior Probability

A method of updating distributions that requires that prior distributions of the required geological characteristics are defined and that calculation of the posterior distributions be based on an exact stochastic model.

• Sequential Simulation

• Kriging

• Monte Carlo Modeling

• Bayesian Method

A probability based on Bayes' theorem of interdependent events occurring interdependently.

• Bayesian Probability

• Joint Probability

• Posterior Likelihood

• Conditional Probability

Analysis of two data sets that determines whether or not the data are related and describes the best relationship between them.

• Regression Analysis

• Bivariate Analysis

• Cross-plotting

• Multivariate Kriging
