Measurements on Petroleum Rock Samples

SUMMARY:

A data frame with 48 rows and 4 columns. Twelve core samples from petroleum reservoirs were sampled by 4 cross-sections. Each core sample was measured for permeability, and each cross-section has total area of pores, total perimeter of pores, and shape.

DATA DESCRIPTION:

ARGUMENTS:

area
of pores space, in pixels out of 256 x 256
peri
perimeter, in pixels
shape
perimeter/sqrt(area)
perm
permeability in milli-Darcies
