Abstract
A process to determine whether a leak-off event is occurring during the treatment stage of an active borehole. The leak-off event data, such as the severity or magnitude of the potential leak-off, can be communicated to other systems to adjust the treatment stage, the fluid composition, the fluid pressure, or the fluid flow rate. Diverter material can be added to the fluid. The monitoring of the leak-off event can occur over a time interval, such as the time of the treatment stage and periodic adjustments to the treatment stage can be implemented. The leak-off event can be identified when a fluid pressure slope indicates an overall increase in pressure in an adjacent borehole or if the amount of fluid entering an adjacent borehole exceeds a leak-off threshold.
