This Skill provides essential calculations for hydraulic fracture design and analysis, helping engineers estimate fracture geometry, analyze pressure behavior, and optimize proppant placement.
Calculate the PKN fracture half-length for a slickwater stage with a rate of 50 bbl/min, injection time of 90 minutes, fracture height of 150 ft, fluid viscosity of 1 cp, and Young's modulus of 30 GPa.

To calculate fracture half-length using the PKN model, input your injection rate, pump time, fracture height, fluid viscosity, and Young's modulus. The skill processes these parameters to estimate fracture geometry, yielding step-by-step calculations and design parameter tables.
A Nolte-Smith plot interprets net treating pressure trends to diagnose fracture propagation behavior. This skill analyzes pressure diagnostics to help you evaluate fracture containment, identify height migration, or screen-out risks during the treatment.
You can determine fracture closure pressure from ISIP analysis by evaluating pressure decline data after shut-in. The skill guides you through step-rate test interpretation and G-function analysis to pinpoint closure pressure and calculate fluid efficiency.
Yes, you can calculate proppant settling velocity and design proppant schedules for shale completions. The skill determines settling velocities, evaluates pack conductivity, and generates proppant schedules based on your formation properties and treatment parameters.
The difference between PKN and KGD models for fracture geometry estimation lies in their assumptions about fracture shape and height constraints. This skill calculates fracture length, width, and volume using both analytical models so you can compare results for your specific reservoir conditions.
To calculate fluid loss coefficient and fluid efficiency for hydraulic fracturing, the skill processes your pressure decline data and treatment volumes. It yields fluid efficiency calculations alongside net treating pressure and fracture volume estimates for completions optimization.
