A-591, PARKER, T J Survey, La Salle County, Texas

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

4 of 5 wells are drawn. The rest file no coordinate this site will place — either none at all, or one rounded so coarsely that it names a region rather than a wellpad. They are listed below and not pinned. An absent pin is an unfiled coordinate, never a well outside this abstract.

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.
