Gas Bubble Growth With RiseIn A Water Column292 cm 3surface14.7 psi (1 bar)2 cm 35000 ft 2150 psi (146 bar)(1524m)1 cm 310000 ft 4300 psi (292 bar)(3049m)Gas column is different – gas is low density at the top of a52887040.pptcolumn and higher density at bottom – so although rate isconstant, velocity is not.www.GEKEngineering.com 14
Liquids in Gas Wells• Gas phase – condensing to a liquid– Water – several bbls/mmcf, unusually fresh– Condensate – can be much higher volume• Connate Water– Usually saltier than condensing water– Often stays in bottom of the well.www.GEKEngineering.com 15
