What is downhole logging? – …
WebDownhole logging was performed in Hole 1253A after it had been drilled to a depth of 600 mbsf with a 9 -in RCB drill bit. The hole was opened to a depth of 423 mbsf using a 14 -in bit, and a 10 -in casing was installed beneath the sedimentary section into the upper sill to a depth of 413 mbsf. WebDownhole logging tools are used to determine physical, chemical, and structural properties of the formation penetrated by a borehole. Data are rapidly collected, continuous with depth, and, most importantly, are measured in situ. WebJun 24, 2015 · In the past few years, logging-while-drilling (LWD) devices and downhole NMR spectrometers have also been introduced. Table 1 Whether used as a standalone service or in combination with other logs and core data, NMR logs can provide an improved understanding of reservoir petrophysics and producibility. california to connecticut time difference
