Abstract

Today is one of the most important methods of producing hydrocarbon reservoirs, Proper design of wells and casing pipes to have a safe drill operation in sensitive parts of the formations, which itself helps in the production of faster and more long-term storage from the reservoir. Occupation of some oil reservoirs, including the Bangestan reservoir, in deeper parts of the earth, the cause is which will have a more precise design in implementing the wells of this reservoir in different fields. In the field studied, First, we tried to analyze the image log data and the drill information includes the data mud loss and mud weight, fracture of the field is comprehensively studied in addition to a better and more accurate understanding of the expansion of fractures in the reservoir, investigate their relationship with drilling problems and possibility to change the design of the welded pipes and their location more accurately in Bangestan wells, it should be investigated. History of drilling these wells and maximum mud weight required to drill each hole and Condition of installed casing pipes in different wells were studied and wells that have problems and In them, a different design of the casing pipes is used, separated. In this research, the relationship between continuous problems in wells with formations with the highest percentage of problems, was presented and the type of mud with the weight used for drilling problematic formations has been investigated. Finally, by determining the distribution of wells with difficulty In different areas of the field, the density of these wells in each specific area and are areas susceptible to the problem which leads to a change in the design of the casing pipes, identified and introduced.
