  • Expandable technology gains ground as a planned-in option

    Henry Terrell

    As a first step to redeveloping its North Wilmington unit in California, Warren E&P implemented a pilot project drilling and gravel-packing sinusoidal-shaped horizontal wells. The project consisted of four producer wells and two injector wells with openhole sections 1,800–2,400 ft long and vertical amplitude planned at 110–120 ft. Significant deviations from the original well plan made gravel-pack completion of the wells challenging, but with the help of simulation models, injection rates and slurry weights were optimized, resulting in production rates in line with expectations. Based on the positive results, the operator plans up to 150 additional sinusoidal wells to optimize production in the area.
