A dataset of one high-angel well drilled and logged at Bohai Sea during FY2021

The well is drilled with a 241.3 mm (9.5 inch) bit. During logging, the tool is slide against the borehole wall from the bottom to the top and sampled at 76 mm intervals.

The sieve residue log shows that the logging section is dominated by sandy mudstone formations, and borehole fluid sampling shows that borehole fluid has a density of 1.18 g/cm3 with a salinity of 94 kppm. Neutron and density data are obtained according to the log depth interval. The dataset includes 4 files: XX19-1N.xtf is the original data from the well log that could be opened using a xtf viewer. XX19-1N-Data.txt is the data read from the original xtf file. detection.py is the data processing code and XX19-1N. las is the neutron porosity data that are processed using detection.py.
