... research conducted in the field of CFD (Computational Fluid Dynamics). This paper is focused on the application of DTA to petrophysics and its fundamental distinction from various other statistical methods adopted in the industry. Case studies are shown, predicting porosity and permeability for a variety...

... ABSTRACT A technique is described for enhancing the accuracy of estimated permeability curves for the Sognefjord formation of the Troll field. Statistical methods are used, querying a field-wide database built from core data, its geological descriptions, and wireline logs. The Troll field...

... ABSTRACT A statistical method for determination of water saturation from logs is described. The method consists of defining a parameter P in terms of formation resistivity and porosity tool response. It is found that P1/2 has a normal distribution for zones whose water saturation is 100...

... correlation is not merely a matter of tracing a convenient horizon from log to log across a field. It should imply a principle of total or partial lateral equivalence of correlatable units. This is not implied in curve matching. A simple statistical method has been applied to neutron well logs to try...
