GCAP Mobile provides facilities engineers with an easy-to-use interface for common calculations they may need on the job. Calculations currently available with GCAP Mobile: Calculate Barrels of Oil Equivalent for gas reservoir Change temperature in degrees F to C and back Change pressure in Bar to PSI to kPa and back Change Standard cubic feet of gas to standard cubic meters of gas and reverse GCAP Mobile also features the John M. Campbell & Co. 2010 Facilities Training Guide, so you can research training on-the-go. he following calculations will be available in future versions of GCAP Mobile: Calculate Gross heating value from MW Calculate dry gas pressure drop in pipeline Calculate total energy from a tanker of LNG Simple calculation of gas capacity for a separator (d, mw,P, T, ks) Water content in a gas at T & P Hydrate formation T for a gas Maximum pressure drop across a choke without forming hydrates Liquid residence time in a separator Calculate total revenue from a production facility Calculate GPM of a gas
