Abstract

Summary

The real-time interpretation of Extra-Deep Azimuthal Resistivity LWD measurements resulted in the extended reservoir characterization of the lithological heterogeneity of the Fort McMurray Formation, including clean sand facies, inclined heterolithic stratification (IHS) facies, and mud-filled channel facies. This lithology was compounded by fluid heterogeneity within the reservoir, including irregular Oil-Water Contacts (OWC), partial reservoir charging, lean zones and top gas zones.

The increase in actual exploited oil reserves (quantitative), was estimated at more than 50 percent compared to the projected reserves exploited by the planned wellbore trajectory.

This new formation evaluation approach was proven while drilling four horizontal producers in the unconsolidated oil reserves with high reservoir heterogeneity, which stressed the need for operators to fully understand their subsurface in order to maximize oil recovery.

This new logging-while-drilling approach offers an opportunity to better understand the oil reservoir, which ultimately leads to increased production performance of Oil Sands projects. Utilization of this technology in future projects will fundamentally change the efficiency of drilling and completion practices within the oil industry.
