The abstract as the Commission draws it, on satellite imagery. The faint outlines are the neighbouring abstracts in Zavala County; click one to open it.

A pin outside the outline is normal. The Commission files the coordinate of the well’s bottom hole and the abstract of the tract where it was permitted. A horizontal well enters the ground in one survey and bottoms in the next, so about one well in five sits outside the shape it belongs to. A horizontal well’s bottom hole sits a median 2,780 m from its abstract against 877 m for a vertical one, which is a lateral’s length. The Commission also states that its coordinates are interpreted from survey boundaries and are not necessarily true geographic locations.
