Abstract

Functions of the gypsum/salt-bearing sequence in the buildup and storage of hydrocarbons

Author(s): Daniel Levine

Around the world, gypsum/salt beds have been extensively developed in petroliferous basins. It has been demonstrated that most basins with gypsum/salt beds contain a wealth of hydrocarbon resources. The strong sealing ability of gypsum/salt beds as cap rocks was the main focus of earlier investigations on the implications of these beds on hydrocarbon reserves. Gypsum/salt beds have the potential to encourage the creation of high-quality source rocks and hydrocarbon reservoirs, according to an increasing number of exploratory finds. Hydrocarbon production, preservation, and accumulation are influenced by gypsum/salt beds. The study discussed the control of gypsum/salt beds on play elements and examined the relationship between the development of gypsum/salt beds and global large- and medium-scale hydrocarbon reservoirs based on the systematic analysis of the generation of hydrocarbons in global gypsum/salt bearing sequences. Additionally, we looked examined the relationship between typical gypsum/salt bearing sequences and their potential for producing hydrocarbons in China. In terms of the geographical superimposition of gypsum/salt beds and source rocks, a thorough investigation reveals three patterns: the postal pattern, the inter-salt pattern, and the pre-salt pattern. The inter-salt pattern's source rocks, among others, are extensively developed in salt basins and have a lot of potential for oil development.
