... saturation, porosity and permeability limits, and distance to the oil/water contact (OWC). The history-matched model was then used in forecasting the production profile for the new wells using a target liquid production rate of 2,000 STB/D. The production forecast without inflow control showed water...

... drainage is how it appears counterintuitively to limit the flow of oil when water is present near its irreducible saturation. The novelty of the work presented in the complete paper is in the development of a model based on fundamentals of flow in fine channels that better explains observed results...

Applicable saturation-height models are generated based on dedicated core petrophysical rock typing in conjunction with a robust...

.... _ The Johan Sverdrup field permanent reservoir monitoring (PRM) system now has recorded two surveys documenting the progression of the waterflood since production and injection began in October 2019, revealing a clear 4D signal linked to the increase in water saturation. The 4D signals have been used to help...

Accurate petrophysical evaluations (formation lithology, porosity, and water saturation) are essential in characterizing...

... was then benchmarked against the lithology-independent total nuclear magnetic resonance (NMR) porosity. The saturation computation was achieved with the fast neutron cross section method (FNXS) for the gas component and with total carbon for the liquid hydrocarbon fraction. The natural fracture system was analyzed...

Field Introduction Matzen is a supermature oil field northeast of Vienna and is one of the largest onshore oil fields in Europe. The field consists of several stacked...

... The estimation of volume of hydro-carbon in place (HIP) is a key formation-evaluation objective. In 1942, Gus Archie established the algorithm relating bulk resistivity ( R t ), porosity , formation water resistivity ( R w ), and water saturation ( S w ). The Archie equation, and modified Archie methods...
