Hydraulic Fracturing Calculator

Fracturing stages are discrete, whole treatment intervals in the field — you can't pump a fractional stage — so any leftover lateral length beyond the last complete stage interval simply doesn't get its own additional stage. This rounding-down approach reflects how completions are actually designed and executed, where stage count and spacing are planned around whole-number stages first.

Pounds per gallon (ppg) is the standard unit the oilfield industry uses for reporting proppant concentration in frac fluid, making this figure directly comparable to typical frac design specifications and other job reports. Since fluid volumes here are entered in barrels, the calculation converts to gallons first (one barrel equals 42 US gallons) before dividing, so the resulting ppg figure lines up with how the industry conventionally reports this number.

Yes, generally — wider stage spacing means fewer total stages fit within the same lateral length, and since fluid and proppant totals scale directly with stage count, fewer stages means less total fluid and proppant for an unchanged per-stage design. This tradeoff is a real design decision: fewer, more widely spaced stages typically cost less in fluid and proppant but may leave more reservoir rock between fracture networks untouched.

No — it assumes every stage uses the same fluid volume, cluster count, and proppant loading, which is a simplification of real completions design. Many actual frac jobs vary stage parameters along the lateral to account for geological changes or to optimize heel versus toe sections, so this calculator's totals represent a uniform, average-stage design rather than a stage-by-stage as-pumped schedule.
