Abstract: Bobcat Run South Field, Orange County, Texas - Oligocene Frio Formation Hackberry Sand Discovery Utilizing 3-D Seismic Data
Robert L. Zamboras
Bobcat Run South field is an Obligocene Frio Formation Hackberry sand discovery in Orange County, Texas. The discovery is the direct result of 3-D seismic application to hydrocarbon exploration. Highly anomalous amplitude anomalies, or "bright spots," occur within the 3-D seismic data as direct hydrocarbon indicators.
The EDC (Energy Development Corporation) #1 Bean Donner well was drilled on a 40-acre amplitude anomaly. The resulting discovery had a pay thickness of 42 feet with 31% porosity. The recoverable reserve estimate for the well has been calculated to be 3.8 BCF (billion cubic feet of gas) and 106 MBC ( thousand barrels of condensate).
Significant Hackberry sand reserve additions have been made over the last three years utilizing 3-D seismic data. The success rate for drilling of Hackberry amplitude anomalies has been approximately 80% to date.
