Lijin high-pressure

How much pore pressure does a Lijin SAG have?

In the Lijin Sag, 10 wells have normal pore pressure, 9 wells developed moderate overpressure, and 11 wells have high overpressure. c) Overall pore pressure coefficients statistics in the Es3 member.

Which pore pressures are similar in Lijin and boxing sags?

The pore pressures in the Es 3 member in the Lijin and Boxing Sags show similar patterns; low to moderate overpressure was observed in the Boxing Sag in 6 out of 14 wells, while 28 out of 47 wells showed moderate to high overpressure in the Lijin Sag ( Fig. 11 c). 6. Discussion 6.1. Structural inheritance controlled by basin-shoulder faults

Are faults main fluid conduits in Lijin SAG?

This indicates that faults were main fluid conduits in the Lijin Sag. Apart from fluid leakage along fault L1, the geometry of strata also contributes to the high pressure magnitude on the hanging-wall block; hanging-wall strata were flattened towards fault L1, while the footwall sequences favor updip fluid transfer towards fault L1 ( Fig. 9 ).

Are lijin and boxing sags similar?

The Boxing and Lijin sags record a similar tectonic evolution since the Paleocene (Allen et al., 1997; Feng et al., 2013) ( Fig. 1 ). However, faults developed in these two sags vary in terms of their evolution and geometries ( Fig. 4, Fig. 5, Fig. 6, Fig. 7 ). 4.1. Fault families in the Lijin Sag
