Investigation on drilling optimization through DTP and DP

Chronologically oil and gas drilling has started in 3000 B.C by Egyptian. Oil and gas drilling costsTechnology and the kind crude oil significantly affects the cost of petroleum refined products crude oil and Natural gas because these products impact the world economy and modern life .Through researches it has been revealed that the cost of petroleum refined product is continuously increasing from century to century because the depth at which hydrocarbons are being taken is different from one century to another and the uses of these products are continuously increasing etc. For More clarification on handling this well depth matters are grouped in five parts of this book entitled investigation on drilling optimization through drilling tool performance (DTP)and drilling parameters (DP) such as Theories of bit wear and ROP by focusing on Geomechanical aspect The impact of nozzle on drilling efficiency Application of failure criteria in wellbore stability the Impact of welldepth in oil and Gas drilling and Investigation on drilling tool performance . This book is dedicated to all oil and gas organizations and institutions with drilling as responsibility.
