Descrizione del progetto
Ottimizzare la tecnologia per l’estrazione geotermica
L’energia geotermica costituisce una risorsa rispettosa dell’ambiente che possiede il potenziale per soddisfare il fabbisogno di riscaldamento, raffreddamento ed elettricità del futuro. Ciononostante, tale fonte energetica rimane pressoché inutilizzata a causa di dispendiose e prolungate pratiche di perforazione. Il progetto Geo-Drill, finanziato dall’UE, si propone di creare attrezzature di perforazione ottimizzate per ridurre i costi e aumentare il tasso di penetrazione dell’estrazione geotermica. Questa innovativa tecnologia di perforazione nasce dalla combinazione di martelli resistenti azionati insieme ad amplificatori fluidici bistabili, sensori stampati in 3D e cavi per migliorare il monitoraggio, e rivestimenti in grafene per aumentare la resistenza di perforazione e il ciclo di vita. La diminuzione fino al 60 % dei costi di perforazione spingerà gli investimenti rendendo l’energia geotermica ampiamente più accessibile.
Obiettivo
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%.
