Prediction of Flow Properties of Upper Cretaceous Continental Deposits from Petrophysical and Geological Data - T. Field

摘要

1. Core logging established that well 9 penetrated estuary deposits. The whole depositional environment model which was created by electrometric method show us the position of perspective reservoirs (point pars and crevasse splay) and river channel. 2. Different geophysical methods allow us to find dependence for calculating flow properties in wells when a lot of well logs are missing. 3. Geological model helps to estimate the quality of each of lithotypes by flow properties distribution. 4. The purpose of this Project was to predict flow properties and hence establish the reservoir production potential. Based on the above purpose the 3D geological model has been created, which allowed reservoir evaluation and reserves estimation and which can be used for future flow simulation modeling. 5. We recommend to do following for future studies: - drill a well in the north anticline structure - run full logging suite in all new wells - perform NL time measurements in cased well for establishing gas-oil contact precisely - take low-invasion core; - conduct palynology analysis of core data to specify depositional environment of Dl-III formation.
