Disclosed is a method of rapidly hydrating a hydratable polymer, which method involves irradiating with radio frequency electromagnetic radiation, a mixture of at least the polymer and an aqueous hydrotreating medium to form a viscosified mixture of at least aqueous hydrotreating medium and hydrated polymer. Related methods of treating a subterranean formation and continuously hydrotreating a subterranean formation are also revealed.

Polymer hydration method

The annular surface between the tubing and casing of an oil or gas well as well as flow conduits and vessels may be contacted with a foamed treatment composition containing a gas, a foaming agent and a treatment agent. The treatment agent may be an inhibitor or removal agent for scales, corrosion, salts, paraffins or asphaltenes. The foam, upon destabilization, renders a thin film of concentrated treatment agent on the external surfaces of the tubing, inside the casing and in the perforations of the oil or gas well or on the flow conduits or vessels.

Method of treating flow conduits and vessels with foamed composition

The annular surface between the tubing and casing of an oil or gas well may be contacted with a foamed well treatment composition containing a gas, a foaming agent and a liquid well treatment agent, such as a scale inhibitor, corrosion inhibitor, salt inhibitor, scale remover or biocide. The foam, upon destabilization, renders a thin film of concentrated well treatment agent on the external surfaces of the tubing, inside the casing and in the perforations.

Method of treating well with foamed composition

A method for resolving sludge/emulsion formed as a result of adding introduced fluids to oil and gas wells. The method comprises adding a water-dispersible emulsion breaker and/or adjunct additives that may include iron-control chemicals, scale-control chemicals, or paraffin-control chemicals or combinations thereof in amounts sufficient to separate the sludge/emulsion into an oil phase and a water phase and to control iron, scale, or paraffin in the oil phase. Further treatment of water phase includes treatment with water clarifiers, allowing the water phase to remain in settling vessels, and passing the water phase through a macroreticular resin resulting in water that is environmentally acceptable for disposal.

Method for processing returns from oil and gas wells that have been treated with introduced fluids

A method for resolving sludge/emulsion formed as a result of acidization of oil and gas wells comprising the steps of adding an iron-control chemical in an amount sufficient to prevent the formation of insoluble iron compounds, and adding a water-dispersible emulsion breaker in an amount sufficient to separate the sludge/emulsion into clean oil and water. Further treatment of the waste water with water clarifiers, settling vessels and passing it through a macroreticular resin results in water that is at least less than 29 mg/L total oil and grease for overboard discharges from offshore facilities.
