Geothermal drilling industry faces various challenges such as poor overall drilling confidence and performance, and lack of bottom hole awareness resulting in NPT, tripping time etc. OPTIDRILL concept was born to address and solve problems in drilling for geothermal resources that increases uncertainty and well construction costs. OPTIDRILL ´s innovative drilling advisory system is based on a combination of enhanced monitoring systems, multiple data-driven ML modules, each being responsible for either analysis, prediction, or optimization of one aspect of drilling or completion process. OPTIDRILL consortium, brings together highly experienced drillers, drilling project managers, engineers and operators, each having a different, yet complementary set of expertise in differing geological conditions, operating parameters and production end-goals. They will be providing data from various wells around the world. An enhanced monitoring system will be developed based on real time MWD systems as well as acoustic and vibration sensors. The automated machine learning analysis method will predict drilling parameters, using a real-time monitoring and optimization tool, as a unified system combining existing data and the newly developed methods, and finally, a coupled drilling optimization models to reduce overall geothermal drilling and production cost. The goal is to advise and support drilling operators in making informed decisions through real-time data, reducing many of uncertainties associated with drilling, which in term leads to less NPT, as the drilling can be more readily optimised to maintain good ROP, borehole control and address possible drilling issues, before they could impact operation. The OPTIDRILL Advisory System is NOT an attempt to just fully automate drill rig operations, but rather to enhance and digitize decision making and reporting, instrument and optimize the drilling process, and share and transfer this learning across subsequent future application.

Geothermal is the most under-utilized of renewable sources due to high investment costs and long development cycle. A big part (53%) of the cost is in drilling and it is time-dependent. Geo-Drill aims to reduce drilling cost with increased ROP and reduced tripping with improved tools lives. Geo-Drill is proposing drilling technology incorporating bi-stable fluidic amplifier driven mud hammer, low cost 3D printed sensors & cables, drill monitoring system, Graphene based materials and coatings. Geo-Drill fluidic amplifier driven hammer is less sensitive to issues with mud and tolerances, less impact of erosion on hammer efficiency and it continues to operate with varying mud quality in efficient manner. It is also less affected by the environmental influences such as shocks, vibrations, accelerations, temperature and high pressures. Low cost and robust 3D-printed sensors & cables along the surface of the whole length of the drill string provides real-time high bandwidth data during drilling; e.g. estimation of rock formation hardness, mud flow speed, density, temp, etc. Flow assurance simulations combined with sensor readings and knowledge-based system will assist in optimizing drilling parameters and cuttings transport performance and safety conditions. Graphene's ability to tune the particular form lends itself uniquely as a component in a wide variety of matrices for coating developments with enhanced adhesion and dispersion properties and improved resistance to abrasion, erosion, corrosion and impact. Placing few mm hard-strength materials on drill bit, drill stabilizer through diffusion bonding improves their wear resistance and improve the lifetime. Geo-Drill's hammers improved efficiency and lifetime, drill parameter optimisation and CTP via sensors, reduced time in replacing tools with improved lifetime work together to improve ROP & lifetime resulting in reduced drilling time. Thereby, Geo-Drill will reduce drilling cost by 29-60%.
