Wellbore Genius

Formation library

Load the rock you actually logged: one row per layer, with its top and base depth, stiffness, Poisson's ratio, toughness and (optionally) leak-off. Everything you load here is what the cross-section around the wellbore draws, and what the fracture run on the cluster design page grows through.

Sample layers — not your well

Load a full formation log

A whole logged column — every layer with its own stiffness, Poisson’s ratio, toughness, leak-off and density. Loading it replaces the sample layers, so the reservoir grid, the cross-section and the fracture run all read layer-by-layer rock.

Midland 42-7H

Midland Basin — Wolfcamp A

8 layers · 2,120 ft logged · 10,240–10,560 ft TVD pay (320 ft)

Layer tops from Midland Basin log correlation; E, ν, toughness, leak-off and density in the published range for Spraberry/Dean/Wolfcamp/Strawn rock. A reference column, not one operator's measured log.

Your saved formation database

Save the layers in use as a named well and every page — cross-section, fracture run, pad plan and reservoir grid — reads that one set, on any device you sign into.

Cross-section cell view

Grew out of pay

A vertical slice through the rock along the fracture, with the well at the centre. Each cell prints the formation value at that depth; the outlined box is the fracture this cluster's 8.0 bpm makes.
