Abstract: A system for monitoring and establishing physical properties of a subsurface formation at a testing site having a source well and one or more receiver wells may include a pump, a data collection system, and a controller. The controller may cause the pump to extract fluid from and inject fluid into the source well based on one or more measures indicative of an amount of liquid in the source well. The controller may receive measures related to pressures in the receiver wells and physical properties of the subsurface formation may be determined based on the measures related to pressures in the receiver well. In some cases, noise may be removed from the measures related to pressures in the receiver wells to facilitate determining the physical properties of the subsurface formation.

Abstract: Modular hydraulic packer-and-port system and corresponding methods of operation. The system may be installed for temporary, semi-permanent, or permanent deployments. The system and method may provide for hydraulic isolation of target zones in a well while allowing pass-through tubes to the target zones for taking samples, inserting monitoring sensors, and the like.
