Web9 apr. 2024 · The litho-density and compensated neutron crossplot for the Matulla Formation in Tawila N-1 Well is presented in Fig. 7b, c. The photoelectric capture measurement taken by Schlumberger litho-density tool (LDT) is very sensitive to barite, and so it can detect fractures that have been invaded by barite mud (Fig. 7b). WebThe accuracy of the density measurement of the litho-density tool is approximately 0.01 to 0.02 g/cm3, whereas that of the formation density tool is approximately 0.02 to 0.03 g/cm3. The density measurement has a vertical bed resolution of 50 to 60 cm, which is slightly better than the formation density tool. simplisia wortel
