Latest Patents

Derek Barnes holds a patent for a "Method of monitoring core sampling during borehole drilling." This invention involves making downhole measurements to accurately determine whether a core barrel contains an appropriate amount of core sample before the retrieval of the coring tool. The method utilizes a known apparatus for measuring downhole weight on bit (WOB) at the beginning of a coring run. A first measurement is taken to correspond to the weight of all drillstring components suspended below the measurement point at a selected depth. After drilling down the length of the core barrel, a second measurement is taken when the drillstring is pulled up to the same depth. By correcting the data for temperature changes, the difference between the first and second measurements is compared to a calculated weight for a full core. This process allows for the determination of whether a full core has been obtained, thereby guiding the coring operation effectively.
