Application of Bulk Density Image Data in Horizontal Well for Formation Evaluation in laminated Environment

Drilling horizontal well sections has such situations when the well intersects the reservoir boundaries on long-range depths. In such circumstances, some logging methods readings such as gamma-gamma density mothod may be compromized by boundary effects. Interpretation of GIS in horizontal wells requires a special approaches and the techniques. The paper describes some of these techniques, allowing to use the bulk density image data as a source of important additional information about reservoir properties of productive layers. The paper describes the options for using the bulk density image to solve a set of problems :

1. Assessment of the effective thickness of reservoir in horizontal wellbores.
2. The definitions of density of sandy part of the section
3. Calculation of wellbore hydrocarbon infiltration surface downhole
4. Evaluation of effectivenes of well placement in reservoir
