n: an arrangement for producing a well in which one wellbore penetrates two or more petroleum- bearing formations. In one type, multiple tubing strings are suspended side by side in the production casing string. each a different length and each packed to prevent the commingling of different reservoir fluids. Each reservoir is then produced through its own tubing string. Alternatively. a smalldiameter production casing string may be provided for each reservoir, as in multiple miniaturised or multiple tubing- less completions. See dual completion.

n: an arrangement for producing a well in which one wellbore pentrates two or more petrolum-bearing formations that lie one over the other.the tubing strings are suspended side-by-side in the production casing, each a different length and each packed off to
