Field Notes

Short, sourced explainers from the field: flare gas, gas to power, and the common mistakes that cost modular energy projects.

Flare maths

How much power is in a flare?

A whiteboard estimate of the electricity hiding in flared gas: one million standard cubic feet a day is roughly 4 to 5 MW from a gas engine.

Flare maths

Why associated gas rises, then falls

Associated gas rate is oil rate times gas-oil ratio, and the product is usually a hump. Why a plant sized to day-one gas flares or idles.

Common mistakes

One 1,000 kW genset: 590 kW at 45°C

Gas engines and turbines lose output in heat. Why plants in hot climates must be sized on the site-rated curve, not the ISO rating.

Common mistakes

Most of your fuel leaves as heat

A gas engine turns roughly 28 to just over 40% of its fuel into electricity. Recovering the heat lifts total efficiency to about 80%.
