Abstract Geothermal energy is used in more than 20 countries worldwide and is a clean, reliable, and relatively available energy source. Nevertheless, to make geothermal energy available anywhere in the world, technical and economic challenges need to be addressed. Drilling especially is a technical challenge and comprises a significant part of the geothermal development cost. An enhanced geothermal system (EGS) is a commercially viable thermal reservoir where two wells are interconnected by some form of hydraulic stimulation. In a commercial setting, fluid is injected into this hot rock and passes between wells through a network of natural and induced fractures to transport heat to the surface system for electricity generation. To construct EGS wells, vertical and directional drilling is necessary with purpose-built drilling and steering equipment. This is an application where oil-and-gas drilling tools and techniques can be applied. A recent well, 16A(78)-32, drilled as part of the US Department of Energy's (DOE's) Utah Frontier Observatory for Research in Geothermal Energy (FORGE) program, highlights some of the technical challenges, which include drilling an accurate vertical section, a curve section, and a 5300-ft 65° tangent section in a hard granitic formation at temperatures up to 450°F (232°C). Extensive downhole temperature simulations were performed to select fit-for-purpose drilling equipment such as purely mechanical vertical drilling tools, instrumented steerable downhole motors, measurement-while-drilling (MWD) tools, and embedded high-frequency drilling dynamics recorders. Downhole and surface drilling dynamics data were used to fine- tune bit design and motor power section selection and continuously improve the durability of equipment, drilling efficiency, and footage drilled. Drilling optimization techniques used in oil and gas settings were successfully applied to this well, including analysis of data from drilling dynamics sensors embedded in the steerable motors and vertical drilling tools, surface surveillance of mechanical specific energy (MSE), and adopting a drilling parameter roadmap to improve drilling efficiency to minimize drilling dysfunctions and equipment damages. Through drilling optimization practices, the instrumented steerable motors with proper bit selections were able to drill more than 40 ft/hr on average, doubling the rate of penetration (ROP), footage, and run length experienced in previous granite wells. This paper presents a case study in which cutting-edge oil-and-gas drilling technologies were successfully applied to reduce the geothermal well drilling time by approximately half.

Purpose Oil and gas industries play a major role for the growth of world economy, and drilling operation is considered as most important and hazardous procedure at the same time for oil and gas drilling crew because of the lack of effectual and user-friendly safety and health teaching and learning aids with updated knowledge and training capability. According to the previous studies, there is an urgent industrial need for user interactive technological aid for enhancing the teaching and learning of oil and gas drilling crew and safety officials at onshore and offshore drilling domains to fulfill the requirements of fourth industrial and educational revolutions. Therefore, this proposed virtual reality (VR)-based Hazard Free Operation (HAZFO Expert 2.0) teaching and learning aid to reduce the workplace risk and hazards to enhance the vestibule and experiential learning performance of oil and gas drilling process at Pakistani drilling industries. Design/methodology/approach In this proposed product based study for interactive teaching and learning application for industry, sequential explanatory research design will be adopted to prevent the accidents according to the modern technologies in this era of IR 4.0. Whereas, for the development of VR-based educational aid for Pakistani oil and gas industries, Autodesk 3ds Max, visual studio and MySQL software’s will be used. Findings This new concept of VR-based interactive educational aid (HAZFO Expert 2.0) for accident prevention at oil and gas drilling industries will be based on potential hazards and their suitable controlling measures for onshore and offshore drilling sites. Practical implications VR-based interactive educational aid for oil and gas workforce will facilitate the health and safety professionals for the elimination of potential hazards associated with oil and gas drilling activities to the next level of identification of hazards which has been identified in HAZFO Expert 1.0 at onshore and offshore drilling sites. Originality/value This proposed VR-based interactive educational aid for safe drilling process will be the first visual teaching and e-learning technology which covers all onshore and offshore drilling operations in Pakistani oil and gas industries and provides effective hazard controlling strategies to overcome challenging industrial hazards.
