Senior Exploration Geologist

The Pikka Unit represents one of the largest conventional oil discoveries in the United States in the past 30 years, with the Pikka Phase 1 Project marking the most significant North Slope development in over two decades. Additional upside is provided by discoveries at the Mitquq and Stirrup exploration wells drilled in 2020, together offering a clear and sustained growth pathway for Santos in Alaska.

Pikka Phase 1 is the flagship Nanushuk development in Alaska and the first in a series of planned projects. Early‑phase technical excellence is essential, given the steep learning curve and the long‑term impact of key development decisions. This is a pivotal period for the Alaska Business Unit, as we approach first oil from Pikka NDB, advance planning for Pikka NDC, Quokka, and Stirrup, and lay the groundwork for future growth through exploration efforts at Lagniappe and beyond.

Maintaining a lean organization while enabling long‑term success requires highly capable personnel who are motivated, effectively deployed, and focused on value creation. The principal duties of the Senior Exploration Geologist is to mature exploration concepts, integrate all available subsurface information, proactively engage with technical peers and support business needs of the business unit.

• Generate value through application of sound scientific principles to identify and high‑grade exploration and appraisal opportunities
• Mature play and prospect portfolio through detailed mapping, depositional framework development, risk description and volumetric assessment
• Integrate 2D and 3D seismic data with well and other subsurface information (regional and prospect specific; structural and strati graphic)
• Develop and apply strati graphic concepts to refine the subsurface description

• Master's Degree or higher in geology

• Naturally inquisitive with high work ethic
• Proven exploration experience in multiple geologic settings
• Proficient in gross depositional environment mapping
• Proficient regional and prospect mapper
