MidTex AutoCAD Well Symbols Legend

This page explains the oil and gas well symbols used on MidTex Texas county maps delivered in AutoCAD (DWG and DXF) format. Each symbol represents a specific well status or type, such as permitted locations, producing oil or gas wells, dry holes, and plugged wells.

Users working in GIS platforms or shapefile-based systems may need to map these symbol numbers to their own symbology standards, as symbol definitions and rendering can vary by software.
