Determination of the gas–water contact (GWC) and free-water level (FWL) from modular formation dynamics tester (MDT) pressure measurements in the Simian-1 well. The plot shows measured pressure (psi) versus true vertical depth subsea (TVDSS, ft), with distinct gas (0.065 psi/ft) and water (0.46 psi/ft) gradients intersecting at the FWL, identified at approximately 7041 ft (2146 m) TVDSS. The discrete data points are characteristic of MDT pressure measurements, which are strategically acquired at selected depths to define the fluid gradients.
