Crusty, there is the sandstone encountered by NT-1 and nt-2 and they now define it as the high confidence zone, of which they attribute 3.45 TCF of giip, but then they go on to say, "Furthermore, the new 3D seismic images a possibly even larger area of gas charged reservoir sandstones, beyond the high confidence area established by the new seismic inversion modelling."
"The interpretation of the 3D seismic has been completed by the Ruvuma PSA operator, ARA Petroleum Tanzania (APT). Seismic inversion geomodelling, undertaken in collaboration with Ikon Geoscience, has defined a high confidence area with a revised in-place volumetric estimate for the Ntorya gas discovery. A most-likely (approximating to P50) estimate of 3.45 trillion cubic feet (Tcf) of Gas Initially In Place (GIIP) is now believed to be potentially connected to the reservoir sandstones encountered in the Ntorya-1 (NT-1) and Ntorya-2 (NT-2) discovery wells. This revised Ntorya volume represents a substantial increase to the published P50 GIIP of 1.64 Tcf estimated by RPS Energy (RPS) in their February 2018 Competent Person's Report (CPR)."
"Furthermore, the new 3D seismic images a possibly even larger area of gas charged reservoir sandstones, beyond the high confidence area established by the new seismic inversion modelling. This provides for potential additional prospective gas volumes associated with the Cretaceous age sand units tested in NT-1 and NT-2 (Units 1 and 2) and for the possible existence of an as yet undrilled shallower sand unit (Unit 3), to be tested by the forthcoming Chikumbi-1 (CH-1) appraisal well later in the year. An upside aggregated GIIP volume for the Ntorya accumulation based on a success case in multiple stacked sands at CH-1, is estimated by APT to be up to 7.95 Tcf (approximated to a mean unrisked P10 GIIP)."
