Pressure Coring in the Terrebonne Basin, Walker Ridge Block 313, Site H, Expedition UT-GOM2-2

This dataset contains pressure coring data from Pressure Coring Tool with Ball Valve (PCTB) deployments including rig data, wireline data, data storage tag data, PCTB settings, recovery pressures, and sediment recovery. Both configurations of the PCTB were used: the face bit (code FB) and cutting shoe (code CS). Timestamped rig and wireline data including rates of penetration, pump rates, wireline depth and tension were plotted with timestamped temperature and pressure data from data storage tags inside the pressure coring tool and on the wireline. These figures along with PCTB settings and traditional coring parameters like % recovery were used to assess the performance of the pressure coring tool. See Expedition UT-GOM2-2 Methods: Downhole Tools and Pressure Coring Results (Flemings et al., 2025a, https://doi.org/10.5281/zenodo.13971228). The attached readme file, previewed below, describes all the data files in this dataset and their contents. The readme file also contains links to where the data is presented in the expedition proceedings. Additional data you might expect to find in this dataset can instead be found at the following locations: Conventional coring deployment data can be found in the pressure coring dataset (https://doi.org/10.5281/zenodo.14518080). Logs of coring data and acquired cores can be found in the curation dataset (http://doi.org/10.5281/zenodo.14926309). For coring logs, download the files GoM2-2 H003 AS DRILLED.pdf and GoM2-2 H002 AS DRILLED v1.pdf. For the core log, download file UT-GOM2-2 CORE LOG depths – sortable.xlsx. See tabs “Core log”, core type “FB” for the Pressure Coring Tool with Ball valve (PCTB) in the face bit configuration (PCTB-FB), and “CS” for the PCTB in the cutting shoe configuration (PCTB-CS). Raw rig and wireline data can be found in the rig operations dataset (http://doi.org/10.5281/zenodo.14680104). This data is documented in Expedition UT-GOM2-2 Site H, Pressure Coring (Flemings et al., 2025b, https://doi.org/10.5281/zenodo.13971276). Processed data can also be found in Appendix C, of Expedition UT-GOM2-2 Site H (Flemings et al., 2025b, https://doi.org/10.5281/zenodo.13971276).
