BACKGROUND

During the production of hydrocarbons from a reservoir, chemical and physical changes may occur within the fluids from the well as they are transported from the reservoir and through a processing system. Fluids produced from a well may be a mixture of liquid hydrocarbons, gaseous hydrocarbons, water and various solids and chemicals. Rapid changes in temperature, pressure and agitation can create changes in the fluid characteristics that can affect the efficiency of the overall production and processing system. Problems that arise as a result of these changes to the fluid characteristics may include deposition of undesired matter in a system, for example, scales, corrosion products, paraffin wax, asphaltenes, napthenates and gas hydrates. Generally, production chemicals are required to mitigate or overcome these types of problems.

Production chemicals, as used herein, may refer to any chemical, composition, formulation, or the like, utilized to support and/or enhance the production, processing, and/or transportation of petroleum products. Generally, production chemicals may include, but are not limited to, chemicals and/or compositions to inhibit one of corrosion, emulsion(s), gas hydrates, scale, bacteria, foam, wax, paraffin, asphaltenes, grease build-up, heterogeneous material build-up, and/or hydrogen sulfide. Many factors may be considered before selecting the appropriate production chemical or combination of chemicals, including, but not limited to, performance, environmental restrictions, compatibility, stability and cost.

SUMMARY

This summary is provided to introduce a selection of concepts that are further described below in the detailed description. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in limiting the scope of the claimed subject matter.

In one aspect, embodiments disclosed herein relate to a method of performing an oilfield treatment that includes delivering to an oilfield fluid a host-guest complex, wherein the host-guest complex is formed from a solution of host molecule mixed with a guest molecule having opposing solubility from the host molecule; wherein the host molecule is present in the solution in an amount of at least 2×10−6M

In another aspect, embodiments disclosed herein relate to an oil-field treatment composition that includes an aqueous base fluid; and a host molecule encapsulating a guest molecule, wherein the guest molecule is not independently soluble in the aqueous base fluid.

In yet another aspect, embodiments disclosed herein relate to a method of treating a fluid that includes adding an oil-field treatment composition to a hydrocarbon fluid; wherein the oil-field treatment composition includes an aqueous base fluid; and a host molecule encapsulating a guest molecule, wherein the guest molecule is not independently soluble in the base fluid.

Other aspects and advantages of the claimed subject matter will be apparent from the following description and the appended claims.
