ASP Process For Mature Oklahoma Fields

Cano Petroleum (Cano) is a recently formed independent that specializes in increasing production from mature fields using enhanced recovery methods, and field proven alkaline-surfactant-polymer (ASP) flooding is one of the key tools in their arsenal.

Recent Oklahoma acquisitions where Cano is exploring ASP flooding include the Davenport Unit (Prue Sandstone) in Lincoln County and the Nowata Field (Bartlesville Sandstone). In the Davenport Unit Cano drilled and cased two new wells. Data and logs from these new wells are helping design an ASP process for this field. Design of the chemical program is anticipated by year-end 2005 with the program expected to commence soon thereafter. Chemical design is also underway in the Nowata Field, where it is believed that an additional 20-30% of the OOIP could be recovered through ASP flooding. As with the Davenport Unit, design should be completed during 2005. Surtek Inc. (www.surtek.inc) is working with Cano in designing the ASP processes.

Surtek's website summarizes performance in ASP projects. In the Daqing Field in China, a pilot recovered 25% of the OOIP. In a 760-acre Canadian project 14.9% of the OOIP was recovered. Chemical costs for different projects, cited in Surtek's website, range from $0.79 to $3.74 per bbl of incremental ASP oil. With current oil price trends, that type of performance leads to opportunities.

Three critical steps in ASP process design are:

• Fluid design
• Fluid-rock compatibility
• Linear and radial core flooding

Surtek notes that it typically takes from six to nine months to complete the different stages of testing for ASP evaluation. Field execution includes proper mixing and injection of chemical solutions, quality control, and monitoring produced fluids and chemicals.
