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: Pason at Free against Mud Engineer's $2.99. Pason also leads on rating (4.6 vs 1.0) and update cadence (every 5 weeks vs every 34 months). Mud Engineer's advantage is review sentiment (100% vs 82%) and chart position (#71 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Pason is free to download; Mud Engineer costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Pason holds the better App Store score, 4.6 against 1.0. That said, the two scores are not equally well evidenced: Pason has 20 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Mud Engineer's written reviews are positive against 82% of Pason's, so the app with the better star average is not the one people write more warmly about.
Mud Engineer ships an update every 34 months, Pason every 5 weeks. The most recent releases landed on September 17, 2026 and September 14, 2026 respectively.
