Summary

Wireline logging temperature readings are known to be imprecise and need to be corrected to more accurately show what the formation temperature is. One issue with correcting logging temperatures is what correction factor to use. Because there are so many correction factors and they are based on different types of data and locations choosing a correction factor for a particular study area can be challenging to deal with. Some previous work has factored in only depth and other work includes time since circulation as a major component. This data set is comprised of bottom hole temperature, depth, and time since circulation that have had seven different correction factors run on the data. The data was consolidated into 6x6 mile cells and [...]

Purpose

Understanding subsurface thermal regimes is critical for petroleum systems analysis. The most common sources for subsurface temperatures in petroleum-producing basins are the bottom-hole temperatures (BHT) recorded while drilling wells. In basins with a long history of petroleum production, such as the onshore portion of the U.S. Gulf Coast Basin, temperature measurements from wells constitute a particularly dense spatial and stratigraphic dataset from which variations in the subsurface thermal regime can be identified and analyzed. However, a primary issue with using BHT measurements is that the readings record a combination of instrument housing, drilling fluid, and formation temperatures masking the 'true' formation temperature. Therefore, various methods to correct BHT measurements have been developed to reflect true formation temperatures.
