Design for operational events throughout well life maintains zonal isolation

Preliminary results for varied temperature and pressure-loading conditions suggest that operators should analyze wells on an individual basis and apply forward-looking design techniques when selecting an annular sealant to meet the operational requirements.Laboratory analysis and limited field results indicate that finite-element analysis can improve sealant design. Initial studies indicate a strong interaction between the long-term effectiveness of the sealant and its sheath properties, the formation properties, the sealant in situ stresses, completion and stimulation operations, and other events.Particularly for a high-risk well, sealant design and placement may now include a study of o...
