Abstract

Formation damage sometimes knows as wellbore damage can cause serious problem to all drilling programs and should be written in mind of all drilling engineers. An understanding of mechanism which can cause and accelerate damage of wellbore has led to the knowledge of what can be done to avoid it, is also essential for all drilling engineers. Different drilling environments such as horizontal drilling and high angle well drilling will cause different degree of damage which can bring to the reduction of oil productivity. This paper discusses the results of a study which revealed that drilling in the horizontal environment was the most critical and could cause severe damage to the formation, followed by the high angle well drilling environment. To overcome or minimize this problem, the most suitable measure is to understand the most appropriate drill pipe rotating speed, pressure differential, temperatures, annular velocity between the drill pipe and bore hole.
