Determining Distribution of “Low” Pressure Arbuckle
Concept: Low SIP on DST’s in mature production indicates
less effective water drive than in areas with higher SIP
Methodology: Map SIP for infill and replacement wells in
mature Arbuckle fields. DST’s in top 30 feet and
> 80 feet of fluid recovery.
Preliminary results: Significant contiguous areas have lower
pressures than would be anticipated for strong water drives.
“Normal” pressured areas 1050#
Moderate pressured areas 550-750#
“Low” pressured areas 300-550#
