Web14 dec. 2024 · Lithofacies and logging curves are categorized by abrupt variations between the Є 1 c and Є 1 l. A bed of purplish-red sandy mudstone (known as the lower red bed ) is stably distributed on top of the Є 1 c regionally, exhibiting relatively strong reflection in seismic sections ( Figure 4 ).
Lithofacies maps show the areal variation in the depositional patterns that make up each genetic sequence within the reservoir interval. The method for constructing lithofacies maps involves extrapolating the lithofacies from the wells into the gaps between the wells.
