This paper documents the application and final results of using surface and downhole tilt mapping to monitor and evaluate downhole drill cuttings disposal at the Joint Industry Mounds Drill Cuttings Injection Field Experiment Project. Knowledge of the crated hydraulic fractures was critical for determining the placement of "core-through" wells to evaluate the fracturing disposla mechanisms for both sandstone and shale intervals. Through "real-time" monitoring of the fracture it was possible to detect fracture height growth while the test was being performed and measure that hte injected fluids stayed in the intended zone. Surface and downhole tiltmeter diagnostics have been widely used for mapping conventional propped and unpropped hyd5raulic fractures: howeve,r this is the first application of the combination of surface anddownhole tiltmeters to evaluate fracture geometry during drill cuttings disposal.
