Mud engineers play a crucial role in ensuring the smooth operation of drilling programs. The Mud Engineer App is an essential tool for mud engineers, providing a foundation for essential drilling calculations. These calculations include Final Mud Weight, Final Volume, Volume 1, Volume 2, End Volume, BBLs required to adjust Mud Weight, Number of Sacks, Volume Increase, lb/bbl, Weight Up, Hydrostatic Pressure, Equivalent Circulating Density (ECD), Annular Velocity, and Pump Output. Calculate the final mud weight by mixing two fluids with different mud weights. Determine the required volume of each fluid with known mud weights and a desired final weight to achieve the desired mud weight. Calculate the number of barrels needed to add a fluid with a known density to reduce mud weight. Weight Up calculation. Calculate hydrostatic pressure from mud weight and true vertical depth. Determine the Equivalent Circulating Density (ECD) from annular pressure loss. Calculate annular velocity from pump rate and hole/pipe geometry. Calculate triplex pump output per stroke and flow rate. Every calculation shows a step-by-step equation worked out with your own numbers and your chosen units, and can be exported as a professional PDF report with input and result tables, your name or company, the date, and an app watermark. All results are saved automatically in a searchable History, with support for multiple unit systems, customizable defaults, decimal precision, and a light or dark theme. Special thanks to Eng. Mahmoud Elbeltagy for contributing to the development of these calculations.

Verdict
The clearest difference is price: RigCLOUD at Free against Mud Engineer's $2.99. RigCLOUD also leads on rating (4.4 vs 1.0) and update cadence (every 2 months vs every 34 months). Mud Engineer's advantage is chart position (#69 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
