Drilling and Cementing Technology

A Risk-Based Approach to Waste-Containment Assurance

With ever-tightening environmental regulations, drilling-waste disposal by downhole hydraulic fracturing is often the preferred waste-management option to achieve zero discharge. However, formation damage caused by solids-laden-slurry injection can cause uncertainties in injection-well performance and waste-containment assurance. Complicating the problems are the many formation-damage mechanisms that are difficult to model. A probabilistic approach based on Monte Carlo simulations has been developed to model formation damage and its contribution to injection-well performance and waste-containment assurance.
