Abstract:The scope of this paper is to use publicly and privately sourced data to compare openhole versus cased hole completion techniques and injection results in select Ohio Class II saltwater injection wells (SWIW). The vast majority of the SWIWs drilled in Ohio the past 10 years have been completed openhole, typically by drilling to total depth and then carefully selecting a large diameter greater than 7-inch casing shoe depth and cementing casing above the Cambrian-Ordovician age reservoirs. That allows for 1,000 … Show more
