This paper reports on the accuracy of virgin rock temperatures determined from drillstem tests (DST's) that was investigated by examining factors that affect the temperatures recorded downhole during DST's. It is shown that virgin rock temperatures can be calculated with a standard deviation of about 1.5{degrees} C. The data base for the investigation consisted of more than 300 measurement series recorded from DST's in the Norwegian North Sea, encompassing temperature readings from 208 DST's in 112 different oil and natural gas wells.
