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|
|[,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.
