Drillstring Toolbox vs MUDSheet

Drillstring Toolbox is a free calculator from Standard DS-1 that gives you the drill-stem load capacities you need! You can choose an API connection (along with the size you're interested in) to find its recommended makeup torque and tensile capacity. Tap the "Tube" tab to find the tensile and torsion capacities for drill pipe tubes as well!

MUDSheet covers the most essential calculation and data in mud engineering. Designed for mud engineers and drilling engineers, MUDSheet is an app that contains 23 most commonly used calculations, ranging from pipe capacity, pump output to mud additives. We, engineers, are often overwhelmed by the information scattered around in various media forms. Now, the most essential information from engineering handbooks, SPE textbooks, IADC manuals, has been distilled into MUDSheet, a must-have application for every mud engineer and technician to get the job done accurately and efficiently. Features: • Engineering calculation in a second • Quick access to drilling equations and chemical formulas • Being convenient for unit setup exchange • Replaces paper charts and tables • Input data validation • Samples for demonstration • Optional function display and flexible order change • Multiple table references on mud capacity, volume, and properties Functions: • Pipe Capacity • Annular Capacity • Pipe & Annular Volume • Pump-Duplex • Pump-Triplex • Pump-Quadruple • Rectangular Tank Volume • Mesh • Nozzle Total Flow Area • Annular Velocity • CaCl2 • NaCl • Brine Density • Brine Viscosity • Specific Gravity • PV/YP in Water-Based Mud • Solids in Water-Based Mud • Mud Weight Adjustment • Temperature • Chemical Formula • Atomic Table • Unit Conversion
