A wellbore schematic is one of the most fundamental documents in petroleum engineering. It provides a visual representation of the entire well architecture, from the surface conductor pipe down through intermediate and production casings to the completion interval at total depth. Engineers, geologists, and operations teams rely on wellbore diagrams for drilling programs, completion designs, workover planning, regulatory filings, and investor presentations.
Despite their importance, creating wellbore diagrams has traditionally been a tedious manual process. Most engineers resort to Microsoft PowerPoint, Visio, or specialized (and expensive) software like WellCAD or Peloton WellView. A single wellbore schematic can take 30 minutes to an hour to draw manually, and updates require starting nearly from scratch. For teams managing hundreds or thousands of wells, this represents a significant time sink.
This free wellbore diagram generator solves that problem. Enter your casing program — conductor, surface casing, intermediate casing, production casing, liner, and tubing — along with set depths, cement tops, perforations, packer depth, and formation tops. The tool instantly renders a proportional, presentation-ready wellbore schematic that you can export as a high-resolution PNG or SVG file.
The diagram shows nested casing strings drawn to scale, cement behind each casing interval (with hatched shading), open hole below the last casing shoe, tubing inside the production string, perforations as zigzag markers, packer location, and formation boundaries with labels. Depth markers along the left axis provide reference points, while string labels on the right identify each component with its outer diameter and shoe depth.
All rendering happens entirely in your browser using HTML5 Canvas — no data is uploaded to any server. Your well data stays on your machine. The tool supports up to 8 casing/tubing strings, 5 formation tops, and automatic hole size calculation.
