(1) Wells drilled by horizontal methods shall comply with the following spacing requirements:

Alternatively, the operator may utilize an appropriate packer at the bottom of the intermediate casing instead of cement. Casing shall have an external collapse pressure rating to handle cement design from termination point to surface. If cement is used, the operator shall use cement with 500 psi compressive strength and have a minimum 8 hour wait, or until cement has adequately set. The operator shall present all cement and casing designs on a specifications sheet with Permit Application for approval. A copy of cement tickets shall be kept on location to be viewed by the inspector until the drill rig is removed. When unknown or over pressured conditions are encountered a 5000 psi rating on casing shall apply. The operator shall attach a copy of all cement tickets to the well history tickets and shall include all volumes and pressures of job from start to finish.
