Comparative analysis of the drilling method of sidetrack
B.M. Bahramly - Azerbaijan State University of Oil and IndustryThe sidetracking is currently one of the main solutions for the rehabilitation of inactive, and increasing the productivity of depleted wells. It is necessary for the oil and gas fields of Azerbaijan. Thus, there are idle or low-debit wells in all developed fields. The main reason to remove these wells from the producing well stock is progressive weakening of productive layer. The sidetracking is one of the important methods to increase the productivity of a collector as the great majority of the fields is in the last stage of operation. The number of the sidetracked wells will gradually increase in the future. There is a lack of the general classification of the methods of sidetracking for these wells.
The paper reviews the main benefits and drawbacks of the sidetracking, and an algorithm for selection of the method of sidetracking based on the bottomhole characteristics as well.
