Abstract
This paper documents the design process and production response of a successful foamed, high hydrofluoric (HF) acid concentration (10% hydrochloric (HCI) acid/5% HF), high volume (150 gal/ft) mud acid stimulation program performed in 1991 on thermal production wells in the Tulare formation of the South Belridge Field. The recommended program was based on the results of laboratory work on Tulare core and a lookback study of a 1989/1990 mud acid stimulation program. In comparison to the prior stimulation program, the 1991 program gave better results; both the total program success rate and the treatment cost per incremental BOPD improved by a factor of 3.
