A system and method monitor a hydrocarbon reservoir for drainage in volumetric three dimensions. Monitoring between wells is imperative for optimum reservoir management and is achieved by mapping the hydrocarbon fluid pathways in a producing reservoir. Unlike conventional 4D or time-lapse reflection seismic imaging systems that use a controlled active seismic source and records reflected seismic energy at receivers, the system and method exploit the minute vibrations, or micro-earthquakes generated in the reservoir layers that are induced by fluid movement. These microseisms are detected as the fluids move in the reservoir.

A seismic communication system suitable to communicate information to an underground device is disclosed. A seismic source (preferably on or near the surface of the earth) generates a timed series of seismic shots. These shots are then detected by one or more seismic receivers underground. Depending on the timing of these seismic shots, and the communication protocol selected, various information may be communicated to the underground target. Such a system is particularly desirable when the underground device includes a perforating gun because the perforating gun may not only be remotely detonated without the drawbacks of previous methods, but the detonation of the perforating gun charges may also be detected, giving an indication whether substantially fewer than all of the explosive charges detonated. The seismic communication system may also be used, as a component within a multi-functional well seismic system, for seismic reservoir monitoring or seismic monitoring of well operations.

A transient electromagnetic borehole system uses an arrangement of sensors deployed in a borehole for reservoir monitoring. Non-conductive casing sections may be used along with an efficient transmitter configured to provide measurements up to 300 m from the borehole. By using multiple receivers, the method can also be used without nonconductive casing.

Data collected during reservoir monitoring may include fiber optic measurements utilizing a distributed sensing system. Downhole monitoring with the distributed sensing system may generate large amounts of data. For example, the system may be capable of producing the functional equivalent of tens, hundreds, or even thousands of sensors along a length of a wellbore. Continuous monitoring of various properties, including temperature, pressure, Bragg gradient, acoustic, and strain, may create a large volume of data, possibly spanning into several gigabytes. Embodiments of the present invention provide techniques for analyzing a large volume of measurements taken in a wellbore without compromising on the integrity of data.

A well-bore monitoring process involving logging the temperature of a soil, rock, and brine mixture present in a carbonate formation continuously, and simultaneously logging the resistivity of the soil, rock, and brine mixture in the carbonate formation continuously. The logged temperature and the logged resistivity are interpreted whereby concurrent events in the logged temperature and the logged resistivity identify dissolution of rock into the mixture and precipitation of scale from the mixture. The simultaneous logging of the temperature and the resistivity is conducted in a well-bore in the carbonate rock formation.
