Varigate

Varigate Downhole Solutions puts three essential oilfield calculators in your pocket — built for engineers, rig crews, and service hands who need fast, reliable numbers at the wellsite. **Casing Calculator** Select any API casing size, weight, and grade and instantly get: • Nominal ID and drift ID • Burst and collapse pressure • Tensile limit • Capacity and total volume for your string length • API 5CT wall-thickness tolerance — nominal, minimum, and maximum displacement with upper/lower variance Covers casing sizes from 4-1/2" to 20" (114.3 mm to 508 mm) and grades from H-40 through Q-125. Switch between Imperial and Metric with one tap — every selection and input converts automatically. **Hydrostatic Pressure** Enter liquid density and depth and get calculated hydrostatic pressure instantly as you type. **Cement Displacement Calculator** Account for fluid compressibility on displacement. Enter TVD, final circulating pressure, casing volume, displacement density, and solid/water/oil fractions to get: • Compressibility percentage • Total displacement volume with compressibility • Additional volume required Clean, glare-friendly dark interface designed for use in the field.
