The First Formation Evaluation

Overview Technologies

Borehole information in real time

Direct measurements of the reservoir rocks and fluid content provide a key part of the information to be collected from the first well in order to estimate hydrocarbon volumes.

Petrophysical information  from logs

Detailed formation evaluation requires high-quality data acquired in the wellbore, using “while drilling” and wireline-conveyed technology. LWD logs provide real-time information with which to make crucial drilling decisions. Wireline logging subsequently provides additional detailed knowledge of formation characteristics and fluids. A comprehensive suite of measurement technologies is available to investigate these formation characteristics in detail. Borehole imaging logs augment these measurements, providing details of depositional features and the stratigraphy and structure of the reservoir.

Reservoir fluids

In exploration wells, an early mud analysis while drilling provides an understanding of the composition of potential pay zones and can have a significant economic impact in optimizing downhole fluid sampling and testing programs.

Smart downhole analysis techniques monitor purity of fluids and ensure samples are representative before they are captured and brought to surface. Services are available both while drilling and wireline conveyed.
