Multiple Proppant Fracturing of Horizontal Wellbores in a Chalk Formation: Evolving the Process in the Valhall Field

摘要

Oil production from this chalk field has been improved signifi- cantly over the last 3 years using multiple proppant fractures placed from horizontal completions. Following early successes, the engineering effort focused on increasing value through engi- neering innovation and increased productivity. This paper describes, through case histories and field data, advances made in the design and execution of these completions over 13 wells in the Valhall field.
