The reasoning behind the inception, rate of development and successful application of current dual, triple and quadruple completions is highly economic in character. Selection of a practical multiple completion hook-up therefore must necessarily involve strong economic considerations. Type and subsequent cost of any multiple completion hook-up is directly related to number of zones to be produced and workover and artificial-lift requirements of each zone. An analysis of available subsurface equipment that makes the modern multiple completion practical in the light of design, advantages and limitations provides a base for selection of components. A systematic presentation of multiple completion hook-ups from the simplest, most inexpensive two-zone completion to the most complex four-zone completion, in order of increasing cost and flexibility provides a graphic systematic base for selection of a practical multiple completion hook-up.
Advancement in multiple zone techniques and equipment has been so rapid in recent years that it becomes difficult even for those who specialize in this field not only to keep up with it, but to maintain an over-all perspective. Hardly a month goes by that a trade publication does not present a new dual, triple or quadruple completion method. Many of these articles not only imply widespread acceptance of the particular method but strongly suggest that previous methods are shortly doomed for obsolescence. The facts are that there are many areas, perhaps an overwhelming majority, where the complex dual, triple or quadruple completion would not be economically feasible.
Operators in these areas are confronted with the problem of selecting not only a practical multiple completion hook-up but one that is economical as well. In order to make this selection they should have as broad a view of all multiple completion techniques and equipment as possible and some sort of systematic method of evaluating each method in light of any given set of conditions. The systematic basis for this selection in our opinion involves (1) number of zones to be produced; (2) flowing, artificial-lift and workover requirements of each zone; (3) general knowledge of various types of subsurface equipment and its limitations; and (4) general knowledge of possible remedial operations that can be performed with certain fundamental hook-ups.
