Measurements on Petroleum Rock Samples
Measurements on 48 rock samples from a petroleum reservoir.
A data frame with 48 rows and 4 numeric columns.
[,1] || area || area of pores space, in pixels
out of 256 by 256
[,2] || peri || perimeter in pixels
[,3] || shape || perimeter/sqrt(area)
[,4] || perm || permeability in milli-Darcies
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 from BP Research, image analysis by Ronit Katz, U. Oxford.
