Uso de agentes espumantes

The document outlines a method for reducing methane emissions in gas production wells by injecting foaming agents (soap) to help lift liquids to the surface, thereby reducing the need for atmospheric purging. It highlights a specific case where emissions were reduced by 2,520 Mcf per year for a single well by changing the purging frequency from bi-weekly to monthly. The primary benefit is the extension of the well's productive life, with capital costs typically ranging from under $1,000 to over $10,000 depending on the installation.

• Foaming agents, such as soap, are used in gas production wells with low bottom-hole pressure to create a gas and water foam that is easier to lift to the surface, which prevents liquids from choking gas flow and reduces the need to purge the well to the atmosphere.
• The use of foaming agents is highly applicable for gas production wells lacking sufficient reservoir pressure to lift liquids, although it is not recommended for condensate production wells.
• A reported reduction of 2,520 Mcf of methane emissions per year was achieved for one well by reducing the purging frequency from every two weeks to once a month, with each purge emitting 180 Mcf of methane.
