KAPPA is a Petroleum Exploration & Production software company created in 1987. The KAPPA software portfolio covers Pressure Transient Analysis (Saphir software), Production Logging interpretation (Emeraude), Production Analysis (Topaze), reservoir simulation (Rubis) and Well Performance Analysis (Amethyste). Most of these applications are now integrated in a single workstation environment, Ecrin. The application portfolio is complemented by Diamant Master, a client-server solution operated by the Diamant module of Ecrin. It was originally designed to process and share permanent gauges data and interpretation documents, but it has since then evolved towards a reservoir surveillance environment. KAPPA also offers Training and Consulting services in the same area as its software portfolio.
