Microscopic Fossils Help Steer the Drillbit

Biosteering – guiding the drillbit using microscopic fossils – has proved to be a useful technique when drilling in complex reservoirs. Examples from the Norwegian Sea demonstrate how the biostratigrapher needs to work in close cooperation with both the technician preparing the samples and the well site geologist.

The Next Generation Subsurface Modelling

Modelling reservoirs using a 3D grid is a common tool for both the geologist and the reservoir engineer. As models increase in structural and stratigraphic complexity the process of creating these grids has become cumbersome. In many cases the results are not satisfactory to either the geologist or the engineer.
