WSO Using Chrome Propionate Crosslinking

On December 1, 1994, Halliburton performed a 100 bbl gelled polymer treatment, using HE® 100 Polymer crosslinked with Prod® XL-200 Crosslinker, which utilizes Phillips Chrome (+3) Technology, on the Phillips Nitschke A No. 2 well in the Texas Panhandle. Forty-six months (October 1, 1998) after treatment, it is calculated this application blocked approximately 237,000 bbl of water from being produced, thus resulting in a substantial savings. Average production results for the Nitschke are listed below:

Before treatment (November, 1994) 33 BOPD 318 BWPD
14 months following treatment (January, 1996) 40 BOPD 150 BWPD
24 months following treatment (November, 1996) 38 BOPD 148 BWPD
32 months following treatment (August, 1997) 32 BOPD 143 BWPD
40 months following treatment (April, 1998) 30 BOPD 150 BWPD
46 months following treatment (October, 1998) 35 BOPD 135 BWPD

The Nitschke A #2 well, located in Ochiltree County, was drilled in 1983 into the Alpar Hunton formation. Two sets of perfs were made at 9,056 to 9,069 ft. Initial production was 700 BOPD.
