dc.description.abstractThis report presents a study of the use of Type 1 and Type 1L cements for use in wellbore applications in New Jersey. A broad range of testing was done to examine the performance of the systems, including unconfined compressive strength, shrinkage, setting time, flowability, electrical conductivity, and permeability. Testing was completed following applicable standardized methods and quality assurance procedures. This work was completed at the request of the NJ Department of Environmental Protection (NJDEP) due to the imminent switchover, industry wide, from Type 1 cement to Type 1L; which will result in low availability of Type 1 cement. N.J.A.C. 7:9D “Requirements for Well Construction and Maintenance; Sealing of Abandoned Wells” currently limits the type of portland cement that can be used to traditional portland cements (i.e, Types 1, II, III and V), but does not allow the use of Type 1L. Therefore, the testing presented in this report is necessary to determine if Type 1L can be used in place of Type 1.
