v: to mix crude oil or oil products rather than moving them as separate batches. See batch.

mixing production. In a well, when two or more zones are mixed to assist in economic production. In a flow line, when multiple crude source streams are mixed.

adj: relating or pertaining to petroleum products with characteristics so similar that they can be mixed together, or commingled.

n: the shipboard procedure of collecting and settling water and oil mixtures. It results from ballasting and tank-cleaning operations (usually in a special slop tank or tanks) and the subsequent loading of cargo on top and the pumping of the mixture ashore at the discharge port. v: to commingle on- board quantity with cargo being loaded.

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

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.

allocation of production among commingled reservoirs according to reservoir production characteristics, tests, etc.
