Abstract
Many of the wells completed today could be classified as short life or harvest wells. Some of these would not be economically feasible using high end completion components, and methods. Monobore wells can be a solution to this dilemma.
This paper will discuss several methods in which monobore well design can save considerable time while lowering the overall completion cost. Several methods will be discussed, and case histories provided to substantiate the results and savings. Methods will include the following:
Disposable completions using minimal completion components.
Cemented monobores using cement-tolerant components, and methods/procedures of completing wells.
Staged cementing completion designs for openhole monobores.
Two-trip monobore systems
Detailed case histories of the methods above, discussing the advantages and disadvantages of each method.
Results of pilot program with live gas lift valves in place during cement operations instead of dummy valves.
Illustrations along with detailed procedures will be discussed to better understand how each completion method can address the numerous opportunities, and problems associated in well completion design. Case histories will be provided to validate each method.
