Figure 7

Synthetic log of GPK-4. The synthetic log shows mud losses from daily report (dark blue curve) and from outflow data (light blue section), GR, occurrences of gas (methane and ethane), ROP, and caliper (CAL1 and CAL2) data. The lithology is the same as GPK-2. Fracture zones are indicated: Z2, Z4, Z6, Z8, and Z9. Permeable zones are in red, partly sealed zones are in green and sealed zones are in blue. Depths are expressed in measured depth.
