About this app

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. Works fully
offline — no account, no ads, no data collection.
