Question

12.2 Figure 12.25 is a short section of the LDT log in the carbonate section of the simulated reservoir model. 12.2.1 From a knowledge of the density curve alone, what ranges of porosity would you ascribe to the seemingly uniform layer from about 12,490-12,540 ft? 12.2.2 By including the Pe measurement, couldyou refine your porosity estimate? What new average value would you estimate it to be? 12.2.3 What proportion of dolomite and limestone does the matrix seem to be? If not constant, what is the range of mixtures?

Explanation / Answer

Bulk density at 12490-12540 is about 2.30-2.35 g/cm3. Considering it as sandstone formation, the humble formula derived from Archie law can help to find out porosity range.

Spectral gamma ray method can distinguish between dolemite and limestone formation .here only natural gamma log is given, therefore we can only identify the shaliness in the formations.
