Abstract: Methods and systems monitor conditions in a hydrocarbon reservoir with a multilateral observation well. The observation well may detect vertical development of a steam chamber that forms in the reservoir during thermal hydrocarbon recovery operations. Further, the observation well may include branches that extend to form vertical bores with temperature sensors for the monitoring, which may occur during the recovery operations performed in other wells since the observation well may be dedicated to only the monitoring.

Abstract: Hydraulic fracturing of subterranean formations has become more complex and detailed as information increases. Methods for calculating and monitoring reservoir pressures during treatment provide unique opportunities to adjust treatments on the fly. Treatments include acid fracturing, fracture acidizing, acid stimulation, propped acid fracture stimulation, hydraulic fracturing, slick water based hydraulic fracturing, foamed based hydraulic fracturing, foam based acid fracturing, foamed based acid diversion, any other physical particulate and fiber based hydraulic fracturing or matrix treatment.
