Technology

Marathon uses state-of-the-art databases to manage upstream information, and significant efforts are dedicated to provide efficient access to high quality data. Much of our information is proprietary; however, a large portion is sourced through information vendors to supplement internal data. We have considerable expertise in geographic information systems (GIS) technologies.

Reservoir characterization is one of Marathon’s strengths. We focus our efforts upon delivering integrated solutions that describe our reservoirs in detail, from broad basin settings to localized variations in individual formations. We emphasize solutions that integrate state-of-the-art technologies in areas ranging from seismic imaging, geologic modeling, petrophysics, reservoir management and production engineering.

Integrated solutions are especially important to formulate development plans for today’s ever-more challenging reservoirs. Examples of ongoing reservoir characterization efforts include deepwater, fractured carbonates and unconventional shale plays.

Drilling and completions are also Marathon strengths. The majority of ongoing operations incorporate horizontal wells, many with laterals over two-miles in length. Other operations include deepwater and conventional developments. The focus of each of these efforts is to deliver fit-for-purpose wellbores at the lowest possible cost over the life of the lease.

Technology efforts for drilling operations are focused upon actuation of traditional downhole tools via Radio Frequency Identification (RFID) signals to improve drilling efficiency. Technology efforts for completions are focused upon multistage fracturing tools (both RFID- and mechanically-actuated systems) and reduced intervention.

Marathon currently holds substantial positions in the Bakken, Eagle Ford, Niobrara, Woodford and Haynesville plays, in addition to being a leading acreage holder in exploratory shale plays in Poland.

Developing, understanding and applying a wide array of technologies, from subsurface imaging to innovative completion techniques, is a key component of Marathon’s success in developing these assets. Our approach to technology in unconventional resource plays does not focus on one particular aspect of a well; instead we focus on the entire life-cycle of a well and integrate technologies geared towards optimal well performance and field recoveries.

Once placed on production, every well must be closely monitored to make sure it continues to operate at maximum efficiency. Optimization of production is critical to ensuring recovery of developed reserves and maximizing revenues. Minimizing volumes and handling of produced water is also of utmost importance.

One area of technology focus is upon artificial lift systems to prevent liquid loading in long vertical and horizontal well sections. A second focus area is upon technologies to treat produced water for use/reuse as drilling and completion fluids.

Marathon continues to develop gas conversion technologies to realize the full potential of our integrated gas business. Gas conversion technologies enable the transformation of stranded natural gas resources (those currently without access to a market) into high quality, cleaner burning fuels. We partner with leading companies to develop a range of technologies in this space, including gas-to-fuels (GTF) and natural gas hydrates (NGH).

Marathon is also working with joint owners of our Canadian mining assets to develop handling and upgrading technologies associated with oil sands resources. These technologies have potential application in both mining and in-situ accumulations.

Emerging technology provides a forward look at technology development to adapt Marathon’s business model to address challenges facing the energy industry and to identify potential investment opportunities that can be leveraged through the Company’s expertise and infrastructure.
