ESP design & surveillance

Design the string. Land it. Then diagnose it.

Nodal ESP design that runs in a browser — with run-in bending checks against your own directional survey, a gas-lift comparison, and an inverse solver that back-solves wear and gas interference from the amps you're already reading off the drive.

What it does

Most ESP software stops once the string is sized.

Sizing is the easy half. The pump still has to survive going in the hole, it still has to be the right lift method for the well, and one day it will stop making rate and somebody will have to work out why. ESP Studio covers all four.

Size it against your own catalog

Full nodal solve — composite Vogel inflow, per-section gas handling, drift-flux tubing hydraulics. Point it at a well and it will design the string for you, then show you the alternatives it rejected and why.

  • Auto-designer with objectives you choose: most production, best efficiency, longest in operating range, lowest lift cost per barrel
  • Tapered strings, gas handlers and charge stages sized automatically
  • Motor, cable and surface kit checked against the casing you actually have

The same well, four ways. 3 % of the rate buys 5 points of efficiency.

Check it survives the trip downhole

Paste your directional survey and ESP Studio works out the bending stress at every housing neck in the string — both as it lands and at the worst dogleg it passes through on the way down. Those are different limits, and the run-in one is usually what bites.

It'll tell you the deepest depth the string can actually be set, which intervals to run in slow, and how much the tubing will stretch when you tally it.

5.8°/100 ft at 2,100 ft run in slow through here ESP landed · 9,480 ft straight hole, 0.4°/100 ft build to horizontal — too deep to set in

Run-in and landed limits are different numbers — checked neck by neck.

Work out why the one downhole is down

Type in what the well is actually doing — rate, amps, the swing on the amps, a discharge gauge if you have one — and ESP Studio solves backwards for the condition that explains it: how much head the pump has lost, how much extra horsepower it's pulling, and how much gas is getting past the separator.

You get a diagnosis you can act on rather than a shrug, and you can push it straight back into the model as your new working baseline.

The amp swing is what separates gas interference from mechanical wear.

Or find out it shouldn't be on an ESP at all

Screen the same well against conventional gas lift and high-pressure gas lift, side by side with the ESP. You get performance curves for both, the injection depth and pressure each one needs, compressor sizing, and a lift cost per barrel for all three.

Sometimes the answer is that the ESP isn't the right call. Better to find that out here.

Your equipment

Design with the curves you actually trust.

Built-in catalogues go stale, and the curves in them rarely match the datasheet in your hand. So ESP Studio lets you bring your own: trace a pump curve off a datasheet with the digitizer, or type the coefficients in, and it becomes a pump you can design against like any other.

  • Trace head and horsepower curves straight off a scanned datasheet
  • Group your equipment into named catalogues and design the whole well against one
  • Custom motors too — efficiency, power factor and full-load amps follow the real nameplate
  • Nothing you upload is shared with anyone else, ever

The physics

You can see where every number came from.

Lift software tends to be a black box, which is a problem when you're the one signing off on the design. ESP Studio is built on published, citable work — Vogel and Standing for inflow and fluid properties, Hagedorn-style two-phase traverses with drift-flux slip, Turpin and the more recent TUALP work for gas degradation, GPSA for compressor sizing, API 610 for the operating range.

Where a model is a simplification, it says so. Where a number is an assumption you can change, it's an input rather than a constant buried in the code.
