Include: Technical Leadership • Develop geothermal well concepts, design bases, functional requirements and well delivery strategies for production, injection, monitoring and make-up wells. • Prepare and assure well designs, including casing and cementing programmes, tubular selection, wellhead and tree specifications, completion design, drilling fluids, directional plans and barrier philosophies. • Define design loads and operating envelopes considering pressure, temperature, thermal cycling, corrosive fluids, scaling, gas content, geological uncertainty and anticipated well life. • Develop drilling, completion, testing, stimulation, workover, intervention, integrity management and abandonment programmes. • Undertake or review casing design, hydraulics, torque and drag, well control, cementing, thermal stress, materials selection and well integrity calculations. • Specify well testing, injectivity and productivity testing, pressure-temperature surveys, production logging, fluid sampling and well clean-up requirements. • Integrate geological, geophysical, geomechanical, reservoir, geochemical and drilling information into well design and delivery decisions. • Provide well performance and operating inputs to reservoir, steamfield, gathering-system and power-plant design. • Lead or contribute to well risk assessments, HAZID, HAZOP, DWOP, peer reviews, technical assurance reviews and design-stage gate reviews. • Ensure that well designs comply with applicable legislation, recognised industry standards, client requirements and good international geothermal and petroleum industry practice. Project Delivery • Act as the client’s wells engineering focal point across FEED, detailed design, EPC/EPCM, Owner’s Engineer and drilling-contractor interfaces. • Prepare and review well engineering philosophies, design criteria, technical specifications, scopes of work, calculations, drawings, drilling programmes and contractor deliverables. • Review drilling contractor, rig, wellhead, casing, cementing, directional drilling, logging, testing and specialist service tenders. • Support technical bid evaluations, contractor selection, procurement recommendations and clarification of technical deviations. • Develop well cost estimates, basis of estimates, drilling schedules, material take-offs, equipment lists and well delivery risk registers. • Monitor contractor performance, design changes, non-conformances and technical queries, ensuring that risks are appropriately assessed and controlled. • Support rig selection and acceptance, equipment readiness reviews, drilling start-up, wellsite operations, testing, commissioning and handover where required. • Review daily drilling reports, operational performance, well incidents and lessons learned, and recommend corrective or optimisation measures. • Coordinate interfaces between wells, subsurface, reservoir, geoscience, geochemistry, process, mechanical, piping, civil, electrical, instrumentation, HSE and project controls disciplines. • Support due diligence, independent technical review, investment decisions and lender or investor assurance for geothermal developments. • Communicate complex well risks and design decisions clearly to clients, project teams, contractors and non-technical stakeholders. • Mentor junior engineers and contribute to technical quality, knowledge sharing, continuous
