Driller's Method vs WellCalc

This app is designed for both iPhone and iPad. This application uses the basic calculations of the Driller's Method to control oil wells after the occurrence of kick during drilling operations on floating platforms and landing rigs. It is an useful tool to import data files to fill kill sheets from our apps: (Driling Hydraulics, Drilling Simulator 1, 2 and 3, MPD Simulator, Kick Game, Kick Tolerance, LOT Simulator and Well Control Simulator 1 and 2) available for sale in our portfolio on the App Store. It is can be applied on the oilfield (see Disclaimer) and also to help in the understanding of the Driller's Method. This app was developed based on existing spreadsheets. There is no comparison with any other software. Our goal was to create a low-cost application with the help of experts to share with drilling engineers, technicians, drillers, students and teachers of drilling engineering. There is no intention to replace the professional softwares. You can contribute with suggestions for improvements, correcting the translation to english, reporting bugs and spreading it to your friends.

WellCalc is a field-ready petroleum engineering calculator for drilling, completions, production, reservoir, and well-control work. Keep the operating context beside the math instead of scattering it across screenshots and notes. WORK FROM A FIELD JOB - Save well name, field, measured depth, hole size, mud weight, and preferred unit system. - Reuse that context across guided workflows and calculations. - Keep recent work and saved scenarios organized by job. CALCULATIONS YOU CAN REVIEW - 97 calculations across 16 engineering categories. - Guided Kill Sheet, Cement Requirements, Trip, Hydraulics, and Economics workflows. - Formula source, formula-set version, operating note, expected range, and safety tier where applicable. - Oilfield and metric units with explicit labels and dimensional checks. - Saved favorites, calculation history, notes, and reference tables. - Audit-ready PDF field reports and CSV data export. FREE - One Field Job. - Well Control, Pipe & Annular, Pumps, Mud Engineering, and Unit Conversion categories. WELLCALC PRO - All calculation categories and guided workflows. - Unlimited Field Jobs. - Formula provenance throughout the library. - PDF and CSV history export. Your saved jobs and calculations stay on this device. WellCalc does not use generative AI or send calculations to an AI service. Subscriptions renew automatically unless canceled in your Apple ID settings. Restore an existing purchase from Settings > Restore Purchases. IMPORTANT: WellCalc is a field reference, not an engineering approval. Verify safety-critical outputs against the approved program, current measurements, equipment limits, and company procedures.
