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. Works fully
