ABSTRACT: The demand for oil and gas is increasing at a far greater rate than ever before. Geologists across the globe are in search of new reserves. Some of them are easily exploitable some are not. One major problem that we come across in Petroleum industry is Hard formations encountering the successful drilling operation. Drilling through hard formations is time consuming and uneconomical at times. As far as the petroleum industry is concerned time equals money and operations have to be time bound. Here we presented a new technique namely Multiple Control Micro Detonation that can be used to drill through hard rock formations. Multiple Control Micro Detonation (MCMD) will help us to drill through hard rock formations in an effective and time saving manner with minimum expenditure. As for now we have many techniques to drill through hard rock formations, but their effectiveness in terms of money and time is not appreciable and till day hard rock formations are a nightmare for any Drilling Engineer or any Petroleum Engineer. MCMD is very effective and efficient technique when executed with care, precise calculations and also with the help of accurate Geological data. Geological data about proves to be a vital element in the successful completion of this technique at any location. Multiple Control Micro Detonation is a self innovated unconventional drilling technique. As the name suggests this technique uses the power of an controlled explosion or micro detonations to drill through hard formations. Here we use detonators in a controlled manner to make the formation loose. Once the formation becomes loose it can be drilled easily. This paper contains all technical aspects of Multiple Control Micro Detonation .This paper also include Mathematical proofs and calculations involved in this technique. The Mathematical proof given in this paper is a clear evidence of how well this technique can be implemented. This technique can be effectively applied for formation ranging from Medium Hard, Hard, Very Hard and even in Granite formations. Proper and well calculated implementation of MCMD we can counter any kind of hard formation without compromising the economic and safety aspects. Thus this technique will help us to overcome a major problem our Petroleum industry faces, and will contribute in solving the oil crisis the World is facing now.
