System and method for polymer distribution to well sites

A method of distributing polymer to one or more injection well sites in an oil or gas field comprising,

• a) providing a polymer mother solution;
• b) pumping the polymer mother solution through a pipeline or network of pipes from a first location to one or more remote locations comprising at least one injection pod or well site;
• c) mixing the polymer mother solution with water and optionally one or more additional components to form a polymer daughter solution and;
• d) injecting the polymer daughter solution into a well.

A method of distributing polymer to one or more injection well sites in an oil or gas field comprising,

• a) storing or producing a polymer mother solution in a polymer processing station;
• b) pumping the polymer mother solution through a pipeline or network of pipes from the polymer processing station to one or more remote injection pods or injection well sites;
• c) mixing the polymer mother solution with water and optionally one or more additional components at the injection pod or injection well contained therein to form a primary polymer daughter solution and;
• d) injecting the primary polymer daughter solution into the injection well;
• e) extracting oil or gas from a producer well in fluid communication with the injection well, and;
• f) optionally, mixing polymer mother solution with water and if desired, one or more additional components at the injection pod or injection well site contained therein to form a secondary polymer daughter solution, wherein the secondary polymer daughter solution is more dilute in polymer concentration and less viscous than the primary daughter solution,
• g) injecting the secondary daughter polymer solution into the injection well;
• h) extracting oil from the producer well in fluid communication with the injection well, and;
• i) optionally repeating steps f)-h) using successively more dilute and less viscous daughter solutions.
