Drilling & Completions

Horizontal Drilling

Marathon Oil was a pioneer in the use of short-radius horizontal drilling techniques and remains a leader in optimization of horizontal well drilling. Use of integrated teams for real-time directional control, collaboration with service providers on state-of-the-art motors and use of managed pressure and underbalanced drilling techniques demonstrate our ability to provide leading performance in horizontal drilling for shales.

Horizontal Completions

Multistage fracturing systems are a key technology for unlocking unconventional resources. Marathon Oil led the industry with multistage completion technology in vertical wells with the Excape system. As multistage technologies moved to horizontal wells, Marathon Oil continues to innovate as a major developer of the I Ball frac sleeve system and Radio Frequency Identification (RFID) actuated frac sleeve systems for horizontal shale wells.
