Store description excerpt
Oilfield Drilling & Blast Calc is a professional engineering calculator suite built for drilling rigs, mine benches, and quarry pits. Ten focused tools for mud engineers, drilling engineers, blast engineers, mining engineers, and field technicians — all running fully offline, so you get answers whether you are at a remote wellsite, a pit wall, or an underground heading with zero signal. No ads. No subscriptions. No sign-up. Open the app and calculate. WHAT'S INCLUDED: Drilling & Completion - Mud Weight Calculator (FREE): Hydrostatic pressure, mud gradient in psi/ft, pore pressure, frac pressure at the shoe, overbalance, and kick tolerance from mud weight, TVD, and shoe depth. - Casing Burst & Collapse: API 5C3 burst and collapse ratings from OD, grade, and weight, with safety factor, body yield, buoyed weight, and hydrostatic at depth. - Drill String Weight: Compute drill pipe, HWDP, and collar hookload, buoyed weight, and air weight for trip planning. Mining & Blasting - Screen Size Selector (FREE): Pick the correct screen aperture and deck size for target particle cuts. - Pit Slope Stability: Quick factor-of-safety check for open-pit slope angles and bench geometry. - Blast Hole Pattern: Burden, spacing, stemming, and powder factor for surface blast design. - Rock Density & Porosity: Bulk density, grain density, and porosity from lab or field samples. - Mine Ventilation Airflow: Size airflow, velocity, and pressure drop for underground mine ventilation circuits. Environmental & Flow - Flow Weir Calculator: V-notch, rectangular, and Cipolletti weir discharge for field water measurement. - Sludge Volume & Dewatering: Wet weight, dry solids, moisture content, and dewatered volume and weight for pit and process water. WHO IS IT FOR: - Drilling engineers sizing casing and planning trips - Mud engineers mixing and monitoring circulating systems - Blast engineers laying out shot patterns and powder loads - Mining engineers running pit and ventilation checks - Quarry operators screening aggregate - Field technicians and supervisors who need answers on the rig floor or bench WHY OILFIELD & MINING PROS LOVE IT: - Fully offline — works at the wellsite, underground, or deep in the pit with no cell service - No ads and no subscription — pay once, own it - API-aware and MSHA-aware inputs that match the units and conventions you already use on the job - Professional accuracy with clear formulas, unit conversions, and sensible defaults - Clean iPhone and iPad interface designed for gloves, hard hats, and bright sunlight ONE-TIME UNLOCK: Upgrade to Pro for a single $12.99 USD payment (non-consumable, no subscription) to unlock all 8 Pro calculators plus job sheet PDF export. Buy once, use forever — on every iPhone and iPad signed in to your Apple ID. From the rig floor to the quarry bench, Oilfield Drilling & Blast Calc keeps the numbers you need one tap away.
