CALGARY, May 20 /CNW-PRN/ - We are pleased to report the results for the three months ended March 31, 1999. The total cash distribution paid to Unitholders for the period was 32 cents per Unit. This was comprised of regular monthly cash distribution payments of 6 cents per Unit paid on the 20th days of March, April and May respectively plus a supplemental adjustment of 6 cents and an ARTC amount of 8 cents per Unit paid on May 20th. Daily production averaged 3,183 barrels of oil equivalent (``BOE'') per day during the first quarter of 1999, slightly ahead of the 1999 targeted production rate of 3,150 BOE per day. Crude oil and NGLs production averaged 2,041 bbls/day and natural gas production averaged 11.4 MMcf/day during this period. The Fund's 1999 capital development program was formulated to focus primarily on developing natural gas properties during the early part of the year. During the first quarter, development activities focusing on natural gas production were carried out at Bantry and Cherhill, along with oil development activity at Sylvan Lake. A twelve well natural gas infill development drilling program was successfully completed in the first quarter of 1999 at Bantry, Alberta. The program resulted in incremental production of approximately 1,500 Mcf/day gross, 67 Mcf/day net to Westrock II. This shallow gas property will ultimately be developed with a spacing of eight wells per section to provide for the optimum recovery of the proven natural gas reserves. Development wells will continue to be drilled in order to keep existing facilities full. Facility utilization during 1999 will average 85% with this additional operated production and the processing of third party gas production. This increased utilization and the fees generated from processing the third party gas will result in significantly improved operating results for this property during 1999. At Westrock II's Cherhill/Alexis property, the Fund was successful in placing two additional natural gas projects on stream during the quarter. Incremental production to date is approximately 2,000 Mcf/day gross, 80 Mcf/day net. An additional 2,000 Mcf/day gross from this area will be placed on stream in the latter part of the second quarter. The Fund has identified two 100% working interest oil well locations to be drilled in the third quarter to further develop the Pekisko oil pool at the Sylvan Lake property. These locations are offsets to the two successful Pekisko oil wells drilled in 1997 and 1998 which currently produce approximately 130 bbls/day each and have to date recovered in excess of 100,000 barrels of oil in total. Westrock II has also identified additional well optimization work that will be carried out early in the second quarter. It is anticipated that this will result in incremental production of 150 bbls/day of oil net to the Fund. The opportunity to implement a waterflood in the Pekisko zone is under review. This waterflood could substantially improve recoverable oil reserves from this property. Westrock II received an average selling price of $16.36 Cdn. for its crude oil production during the quarter, down from $17.15 Cdn. for the same period in 1998. The average selling price for natural gas liquids for the quarter was $11.15 Cdn., down 42% from the same period in 1998 and the average selling price of the Fund's natural gas was $2.14 Cdn. per Mcf, up 30% from $1.64 per Mcf in 1998. The Fund saw a 30% increase in natural gas prices which helped to offset the lower crude oil and natural gas liquids prices received during the quarter as well as a 14% decrease in daily sales volumes compared to the same period in 1998. Funds flow from operations in the first quarter decreased to $2.1 million from $3.1 million in 1998, however, cash available for distribution was maintained at $3.3 million as a result of receipt of previously accrued net operating income. Strengthening oil prices in the second quarter, combined with strong gas prices, should result in higher funds flow from operations going forward. In February, 1999, a Rights Issue was completed and 801,158 Units were issued at a price of $5.80 per Unit. Proceeds from the Rights Issue were used to fund capital expenditures and reduce bank debt incurred to fund oil and natural gas property acquisitions.
