Answers 2024/2025
Regression is the process of fitting a model to data for the purpose of inference and prediction. (T/F) -
ANSWERSTrue
Which of the following concepts apply to Inference? - ANSWERSInference is about learning something
from the dataset
With inference, you can determine which of the predictors are important.
Inference can help you understand how the response is affected by changes to the predictors.
With inference, you are trying understand the relationship between the response and each of the
predictors
Prediction is the process of making a forecast from a dataset. (T/F) - ANSWERSTrue
Optimization does not always have an objective or goal. (T/F) - ANSWERSFalse
The main goal of history matching a reservoir is to reproduce past production and pressure performance.
This is important, since you cannot predict the future accurately if your model does not at least model
the past with reasonable accuracy. (T/F) - ANSWERSTrue
History matching is a Forward matching problem, not an Inverse problem. (T/F) - ANSWERSFalse
One of the limitations of a history match is that the resulting calibrated model may not reliably predict
future performance if the operating conditions being predicted are substantially different from those
used in the history match. (T/F) - ANSWERSTrue
, The objective function is a key component of an optimization, and defines the goal of the optimization. -
ANSWERSTrue
Excel's SOLVER tool is an example of an optimization tool. - ANSWERSTrue
Which of the following are valid examples of optimization? - ANSWERSFind the shortest route between
College Station and Los Angeles.
Maximize the gas recovery from a field.
Maximize the net present value of a drilling project by varying the spacing between wells.
Which method is used to approximate the partial differential equation for reservoir flow? -
ANSWERSFinite difference
Which of the following are valid finite difference methods? - ANSWERSCentral, Forward, Backward
Discretization refers to a mathematical technique to partition (sub-divide) a continuous function into
discrete intervals or parts. (T/F) - ANSWERSTrue
Analytical models are more complex and computationally intense than discretized simulation models.
(T/F) - ANSWERSFalse
The PDE used to model reservoir flow is non-linear. This is because some of the coefficients of the
derivative term dp/dx are function of p. (T/F) - ANSWERSTrue
Because the PDE of the reservoir simulation flow equation is non-linear, you have to perform what type
of procedure to solve it? - ANSWERSIterative
A material balance model for volumetric undersaturated oil reservoir neglects reservoir flow effects and
assumes constant porosity. (T/F) - ANSWERSTrue
