Cornell University Borehole Observatory Pason Drilling Parameters
This data set included drill rig drilling parameters from well Cornell ESH #1 (API 31109300030000), known as the Cornell University Borehole Observatory, or CUBO. It is a stratigraphic well drilled to characterize potential EGS resources. The Drilling commenced on June 21, 2022 and total depth of 9790 feet below KB was reached on August 13, 2022. The upper part if the well was drilled through 9400 feet of sedimentary rocks before penetrating into 390 feet of crystalline basement rock.
While drilling the CUBO well, rig-related drilling parameter measurement and telemetry was performed by Pason. Numerous parameters were recorded at 1-second intervals, including Rate of Penetration (ROP), Weight on Bit (WOB), torque, hole depth, hook load, standpipe pressure, mud pump rates, flow percent, and mud tank volume. These parameters were used by the driller, the Drill Site Supervisor (DSS), and others to monitor and manage drilling operations and to optimize drilling performance.
The data are provided in CSV format and include a comprehensive list of surface and derived drilling measurements downsampled to 10s intervals. Both Time (10s) and Depth (1ft) domain data sets are provided.
