How this was calculated

Flash gas: Estimated as fraction of total GOR that flashes from separator to tank. Vasquez-Beggs correlation simplified: flash fraction ~ (Psep/1000) x (API/50).

Compressor HP: HP = (flow_MSCFD x compression_ratio x 22) / efficiency. Single-stage for ratio < 4.

CO2e: 1 MSCF methane = 0.042 tonnes CO2e (GWP=28, density=0.0423 lb/scf).
