... for this interval ( Fig. 5 ). The lower block is identified between depths X302 m and X307 m. The GR responses in the upper block and lower block may indicate the presence of a repeat section. The responses of the other logs revealed that the mineral content of the shale has significant variations in the upper...

Paper Number: SPE-212643-MS
... Abstract A challenging step in reservoir modeling is capturing fluid composition variation. This is a complex task as fluid samples taken from wells in different areas of the reservoir usually have large areal and vertical compositional variation. Modeling representative composition variation...

An accurate heat transfer characterization of the well has been implemented to predict the temperature changes along the wellbore during time, as well as the thermal effect due to pressure variations (Joule-Thompson effect). The effectiveness of the implemented algorithm has been proven by its application...
