DEFINITION

Classification: 166/265

(under subclass 244.1) A process comprising separating a stream of material which has entered the well into two or more portions and as a result of such separation delivering the material coming out of the top or head of the well to two or more separate repositories or transmission lines.

(1) Note. One of the repositories may be the same well from which the material flows.

54, for apparatus including float controlled valves for

separating fluid in a well.

105.5+, for wells having structure for separating gas from well fluid.

313, for a multiple completion well in which separate streams of material enter the well from separate formations and come out of the top of the well for delivery to separate repositories. SEE OR SEARCH CLASS

23, Chemistry: Physical Processes, appropriate subclasses for sampling involving the use of sorbents or chemical treatment. A well may be broadly recited as a source.

62, Refrigeration,

58, 123+, and 600+ for processes and apparatus for separation of a mixture by refrigeration even though broadly related to a well.

95, Gas Separation: Processes, for processes of gas separation, per se, especially

241+, for degasification of liquid.

96, Gas Separation: Apparatus, for apparatus for gas separation, per se, especially

155+, for degasifying means for liquid.

196, Mineral Oils: Apparatus, for apparatus for treating mineral oils not disclosed as in a well nor in the pores of the earth even though a well is named broadly as a source.

208, Mineral Oils: Processes and Products, for processes of treating mineral oils not disclosed as in a well nor in the pores of the earth even though a well is named broadly as a source.

210, Liquid Purification or Separation,

600+, for a process of separating the components or constituents of a liquid-liquid or liquid-solid mixture. 417, Pumps,

435, for pumps having means for venting gas from pumped liquid.

422, Chemical Apparatus and Process Disinfecting, Deodorizing, Preserving, or Sterilizing, appropriate subclasses for sampling apparatus involving the use of sorbents or chemical treatment. A well may be broadly recited as a source.

423, Chemistry of Inorganic Compounds,

210+, for processes of separating or purifying gases by a chemical reaction.
