Figure 8: (a) Plot of porosity derived from well logging interpretation against depth in well TS1. The solid line shows the porosity-depth relationship of carbonates according to Schmoker and Halley (1982). The dashed rectangle shows the porosity ranges of carbonates buried below depth of 5000 m. (b) Porosity variations interpreted from well logging in intervals 1–5 with core photos. Note prevalence of dissolved, less-cemented open vugs present in the deeper part of the well.
