Sand injectites

A study was conducted to understand the impact of injectites (sandstone dikes and sills), subsurface exploration, and hydrocarbon reservoirs. The study used sediments of the Great Valley sequence disintegrated from the Sierra Nevada mountains. It was observed during the study that a injection event caused the formation of the Panoche injectite complex and some of the dikes reached to the ocean. The study also used dating techniques for marine fossils to determine the exact timing of the injection event. The distribution and orientation of injectities at the Panoche helped to determine the state of stress at time of sand intrusion. FMI Fullbore Formation MicroImager, the OBMI OilBase MicroImager, and the UBI Ultrasonic Borehole Imager are some borehole imaging tools that can be used to detect sand injectities.
