Homework 1 Key
Reservoir Engineering:
Primary Oil Recovery
20 points
Sections 14 and 15 deals with the variation of reservoir properties with depth.
The
purpose of this exercise is the further explore this phenomena with our own data set.
Used the data set TORISClass.xls in this exercise.
This data tabulates the average
properties from over 1000 onshore US reservoirs.
The engineering data are in Excel
columns C AQ, and the geologic parameters are in columns ARBJ of the sheet Edited.
1.
Construct a correlation matrix between the engineering parameters.
List below the
engineering quantities that correlate significantly (absolute value of correlation
coefficient >0.6) with depth.
The quantities that correlate with depth are initial and current formation volume factor,
temperature, and current and initial pressure.
2.
Construct plots initial average pressure (column AI) and temperature (R) versus depth
(P) in the style of Fig. 112.
You should omit any reservoir that does not have entries for
