A method for improving flow conditions in a porous media while servicing a well penetrating to the porous media includes: stopping drilling or production activities on the well; introducing a well control fluid into the well and the porous media, the well control fluid comprising a mixture of a surfactant, a co-surfactant and a carrier fluid; holding the well control fluid in the well and the porous media in the presence of water while the well is being serviced, such that the fluid penetrates the porous media and forms a water film on surfaces of the porous media; and when well servicing is finished, resuming drilling or production activities on the well.

Working/control fluid for heavy and extra-heavy crude wells

A combined injection and production method includes establishing a production well and an injection well into a hydrocarbon-bearing formation; introducing a mixture of a surfactant, a co-surfactant and a carrier fluid into each of the production well and the injection well so that the mixture flows into porous media surrounding the production well and the injection well; holding the mixture in the porous media surrounding the production well in the presence of water for a period of time sufficient to form a water film on surfaces of the porous media surrounding the production well; and injecting an injection fluid into the injection well while producing from the production well, whereby hydrocarbons flow from the porous media around the injection well toward the production well.

Formulation and method of use for exploitation of heavy and extra heavy oil wells

A combined injection, production and transportation method includes the steps of introducing a mixture of a surfactant, a co-surfactant and a carrier fluid into each of a production well and an injection well so that the mixture flows into porous media surrounding the production well and the injection well, and holding the reservoir mixture in the porous media surrounding the production well in the presence of water for a period of time sufficient to form a water film on surfaces of the porous media surrounding the production well. An injection fluid is then injected into the injection well while producing from the production well, whereby hydrocarbons flow from the porous media around the injection well toward the production well. An injection mixture of a surfactant and a carrier fluid is injected downhole into a desired point in tubing of the production well so that the tubing injection mixture mixes with the production stream forming an emulsion, and the emulsion flows through the tubing to the wellhead. The emulsion can be transported to intermediate locations and then broken and re-formulated for further transport.
