Field-Ready ESP Calculations
Built for the Permian

Free electric submersible pump tools for production optimization, troubleshooting, and equipment sizing. No login required. Works offline on your phone.

Calculator Modules

Six specialized tools covering the calculations ESP consultants and field engineers use daily.

Basic Calculators

Essential ESP field calculations in one place. Handle unit conversions, electrical parameters, and fluid properties.

  • PSI ↔ Feet of Head (with specific gravity)
  • Cable voltage drop (14 AWG through 1 AWG)
  • Affinity laws for pump speed changes
  • KVA / KW / HP conversions (3-phase)
  • Total Dynamic Head (TDH)
  • Tubing capacity with annular volume

Well Snapshot

Generate a complete well summary from current operating parameters. Combines pump curves, fluid properties, and wellbore geometry.

  • Operating point on pump curve
  • Current draw vs. nameplate analysis
  • Intake pressure and submergence
  • Gas-to-liquid ratio at intake

Gas Handling

Calculate gas interference effects and separator requirements for high-GOR wells common in unconventional plays.

  • Free gas at pump intake (Vogel IPR)
  • Gas separator efficiency requirements
  • Turpin correlation for gas slugging
  • Natural separation in casing annulus

Stage Design

Size pump stages for target rate and head. Accounts for gas effects on stage performance in gassy wells.

  • Stage count for target TDH
  • Head degradation from free gas
  • BEP targeting for efficiency
  • Multiple pump series comparison

BGAN Antenna Pointing

Calculate satellite look angles for Inmarsat BGAN terminals used in remote well monitoring. Essential for sites without cellular coverage.

  • Azimuth and elevation to Inmarsat-4 satellites
  • Magnetic declination correction
  • Coverage zone verification (Americas, EMEA, APAC)
  • Visual compass display

PID Response Translator

Normalize PID tuning parameters across different drive and controller manufacturers. Convert between vendor-specific formats.

  • 12 drive/HMI profiles supported
  • Schneider, Vacon, Yaskawa, Triol chassis drives
  • SPOC, Valiant, Levare HMI controllers
  • Plain-English output (Hz/sec ramp rates)

Built For

Anyone who works with electric submersible pumps in the field.

ESP Consultants

Quick field calculations without digging through spreadsheets or vendor software.

Production Engineers

Verify equipment sizing and troubleshoot underperforming wells.

Field Technicians

Mobile-friendly tools that work offline at the wellsite.

Operations Teams

Standardized calculations across your ESP fleet.

From the Field, For the Field

ESP Calc was built by an ESP consultant working daily in the Permian Basin. Every calculator addresses a real problem encountered during troubleshooting, installs, or production optimization.

The tools are designed to work the way field engineers think—quick inputs, immediate results, no unnecessary complexity. Works offline because cell service at the wellsite is never guaranteed.
