The Lithology Editor
The lithology editor allows you to build a real or imaginary sequence of
rock layers, each characterized by its mineralogy, drilling and log
responses. The figure shows a typical sequence, where each layer is
characterized by its number, depth, thickness, fracture gradient, its
drilling softness S and abrasivity W, the three logging values of Gamma
Ray Activity (GA), Resistivity (Res), Porosity (Por), the fluid type and
the pore fluid pressure gradient.
Each of the layers can be edited or new layers created by using the
edit buttons at the bottom of the screen.
When you have done this, you can preview the
fracture pressure and pore pressure gradients or look at the
log response
