Kappa Ecrin v5.10.04 KAPPA is the leading provider of Dynamic Data Analysis software, training and consulting services. Data are analysed on whatever scale is available, from high frequency, high resolution transient data through low frequency, low resolution rate data in production analysis and on into full field history matching and vertical description using production log and formation test analysis. Released in 2016, Generation 5 speeds workflows, connectivity and provides a powerful platform for the future and automation. KAPPA Workstation is an integrated engineering suite which offers analysis and modeling tools for reservoir dynamic data. Our clients told us to ‘think open and think big…’ For this reason, Generation 5 is fully 64-bit, it uses parallel processing for today’s multicore processors and data is fully integrated between KAPPA modules and other programs via OpenServer. Moving deeper into the reservoir and typically making use of low resolution, low frequency data Rate Transient Analysis (RTA) has recently come of age. Evolving from empirical decline curve methods to modern methodology that shares much with pressure transient analysis (PTA). With over 1400 commercial licenses, Topaze NL, the KAPPA Workstation RTA tool, offers single and multi-well analytical and numerical analysis leading to reserves and production forecasting from the most simple to most complex multiphase case.
