Abstract: The “Smear Effectâ€‌ observed during a casingwhiledrilling operation helps reduce lost circulation, provides wellbore strengthening, and improves the fracture gradient so we can drill more effectively through depleted ...

Abstract: The increasing complexities of wellbore geometry imply an increasing well cost. It has become more important than ever to achieve an increased rate of penetration (ROP) and, thus, reduced cost per foot. To achieve maximum ...

Abstract: The increasing complexities of wellbore geometry imply an increasing potential of damage resulting from the casingwear downhole. Much work has been done to quantify and estimate wear in casing; however, the results of such ...
