Application of RED to Down-hole Drilling Mechanics of Various Geological Formations.
Resonance Enhanced Drilling (RED) is a new drilling technology which potentially offers to significantly lower costs of drilling and enables more efficient downhole drilling operations. The idea is based on resonance which is the tendency of a system to oscillate at greater amplitude at some frequencies. As a result, smaller driving force is needed to oscillate the system.
The aim of this research project is to study the downhole drilling mechanics in various geological formations in order to:
• enhance borehole stability,
• investigate the borehole pressure distribution and role of fluids to enhance drilling performance,
• investigate the influence of the drill-bit geometry.
This technology can be utilized to drill different and sometimes challenging geological formations. Various geological formations and their rock mechanics must be studied in order to predict the rock behaviour in response to excavation, stresses, drilling fluid flow, etc and engineer the operation. With oil and gas exploitation from deeper reservoirs onshore and under the seabed offshore, high pressure high temperature reservoirs and also high angle boreholes, it is very important to study and work more in order to well predict and ensure the borehole stability.
