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.

having multiple and often separate completions into different producing pays but in the same wellbore. The completions may be concentric or side-by-side where the pays are not to be commingled or stacked where the flow is to be commingled.
