Documentation

Measurements on Petroleum Rock Samples

Measurements on 48 rock samples from a petroleum reservoir.

Usage

rock

Format

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

Details

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.

Source
