Development Geologist

Job SummaryThe Development Geologist owns the geologic framework behind Flywheel's Eagle Ford development program in South Texas (Gonzales, Lavaca, Fayette and DeWitt counties). Responsible growth starts underground. This role decides where our development capital goes (well locations, landing zones, spacing and development sequence) so that each well recovers the most capitally efficient resource. You will then check every result against the prediction to sharpen the next decision. You will work inside the Eagle Ford asset team alongside reservoir engineering, drilling, completions, operations geology and reserves. It is a mid-career, hands-on role for a geologist who wants their maps and insights to become the drilling schedule. Key ResponsibilitiesDevelopment Planning & InventoryOwn structure, isopach, and reservoir-property maps for the Lower and Upper Eagle Ford (and Austin Chalk where relevant) across the assetDefine landing zones, target windows, and stacking/spacing concepts with reservoir engineering; quantify geologic risk by locationMaintain and high-grade the drilling inventory; support pad selection, sequencing, and the multi-rig development scheduleProvide geologic inputs to type curves, reserves bookings, and the annual plan Post-Drill & Performance LookbacksCompare results against prognosis and forecast (zone placement, lateral quality, early production) and explain the varianceIdentify geologic drivers of well performance (thickness, rock quality, clay, pressure, parent–child depletion) and feed them back into targeting and frac designSupport refrac, workover, and infill candidate screening with geologic and depletion context Integration & DataIntegrate logs, petrophysics, core, 3D seismic, geomechanics, and production data into consistent asset models and gridsKeep geologic data and interpretations current, documented, and accessible to the asset teamPair geologic interpretation with the asset team's data-driven tools (well-performance models, type curves, depletion and spacing analytics) to test which geologic drivers move resultsContribute to acquisition, trade, and partner-well evaluations as needed Team of TeamsAct as the geologic point of contact for the Eagle Ford development programConnect the Eagle Ford asset team with Subsurface Innovation, operations geology, completions, reserves, and land, so information moves between teams as freely as it does within oneCommunicate clearly to technical peers and leadership; present recommendations at well reviews and planning meetings Required QualificationsBachelor's degree in Geology or Geoscience5+ years of upstream oil & gas experience with a primary focus on unconventional (horizontal shale) developmentDemonstrated subsurface mapping, well planning, and development-targeting experienceProficiency with industry-standard geologic interpretation and mapping software (e.g. Petra, Kingdom, Petrel, ArcGIS) Preferred QualificationsMaster's degree in Geology or GeoscienceEagle Ford / Austin Chalk or analogous Gulf Coast unconventional experienceExperience with spacing, parent–child, and well-performance analysis in partnership with reservoir engineeringWorking knowledge of petrophysics, seismic interpretation, and geomechanicsWorking data skills: Python or SQL, plus Spotfire or Power BI, on large well and production datasetsExperiences integrating workflows with new technologies (AI)Geosteering familiarity (e.g. StarSteer)
