About Houston

ExxonMobil's state-of-the-art campus north of Houston serves as home to its Upstream, Product Solutions and Low Carbon Solutions businesses and their associated service groups. The facility opened in 2014 and accommodates more than 10,000 employees and visitors.

By bringing many global functional groups together, the campus provides employees with the tools and capabilities needed today, and in the future, to achieve business objectives and accelerate the discovery of new resources, technologies and products. It was designed to foster improved collaboration, creativity and innovation and enhance the company’s ability to attract, develop and retain the top talent in the industry.

The campus is located in Spring, Texas, on 385 wooded acres immediately to the west of Interstate Highway 45 (I-45), at the intersection of I-45 and the Hardy Toll Road, approximately 25 miles from the cultural vibrancy of downtown Houston.

The campus was constructed to the highest standards of energy efficiency and environmental stewardship. Its design incorporates extensive research into best practices in building and workplace design through extensive benchmarking of the world’s top academic, research, and corporate facilities.

What role you will play in our team

The Unconventional Operations Geologist integrates drilling, injection, completions, and geoscience data to optimize casing design and improve lateral drilling and completions efficiency for assigned wells. This role delivers technical recommendations through collaborative pre‑drill workshops and detailed pre‑drill documentation to guide well design and execution decisions. In addition, the position provides execution‑phase support to geosteering specialists and drilling engineers to help ensure safe and efficient well delivery.

What you will do

Casing point & target window optimization – use log data (e.g. ROP, GR, MSE) and learnings from offset horizontal wells, along with Wellbore Stability (WBS) Models, to make precise casing point and well placement recommendations that improve ROP, reduce non-productive time (NPT), the risk of hole problems, and the need to trip out of hole.

• Collaborate with drilling engineers to determine optimal casing design for assigned wells
• Collaborate with business unit Development Geologist to ensure target windows exclude drilling hazards and make recommendations to adjust if necessary  
• Construct maps, cross sections, and other displays to effectively communicate recommendations and geoscience principles to non-geoscientists using standard wireline log, 3D seismic, well cuttings, mudlog, and drilling data

Wellbore stability modeling - Provide and deploy vertical and horizontal wellbore stability models for all assigned wells. 

• Responsible for generating and revising wellbore stability models as required and ensuring that they incorporate offset drilling, pressure data, best estimate of the local collapse gradient, pore pressure gradient, and fracture gradient from the vertical section through the horizontal target window 

Execution Support - Provides geologic and geomechanical support in execution phase to enable safe, efficient well delivery

• Construct documents for and participate in pre-spud meetings for all assigned wells 
• Facilitate collaboration and dissemination of information between Ops Geology and business unit development geologists 
• Act as a longer-lead POC for assigned areas in line with the business unit team structure 
• Provide geologic context and recommendations slides in After Action Reviews (AAR) as needed 

Data science – Push optimization of drilling efficiencies via geoscience and drilling data-driven decisions

• Leverage existing and create new workflows and dashboards that incorporate all available subsurface and drilling data to maximize drilling efficiency 
• Develop novel methods for integration of wellbore stability modeling products to aid in execution planning and real-time decision making 
• Collaborate with drilling data science team to identify potential improvement opportunities in modeling and data pipelines 

About you
