Summary: This study focuses on the detailed study of the characteristics of the Early Jurassic Datta Formation in the Trans-Indus Ranges of Pakistan. The discovery of gas and condensate in the Saib well-1 indicates the potential for extensive exploration in the study basin. The analysis of various laboratory techniques shows that the Datta Formation has good reservoir quality and was deposited in a deltaic environment.

Summary: In this study, an integrated lithofacies, optical microscopy, and scanning electron microscopy (SEM) analysis were used to investigate the sedimentary processes, depositional architecture, and reservoir rock potential of the Tredian Formation's mixed siliciclastic and carbonate succession in the Salt and Trans-Indus Ranges. Four distinct types of lithofacies were identified based on sedimentary structures and lithology, suggesting different depositional environments. Petrographic examination and diagenetic investigation revealed the presence of primary and secondary cements, which influenced the reservoir quality of different lithofacies.

Summary: This study focuses on the structural deformation in the foreland basin and folded mountain front, using Manzai Ranges in the Trans Indus Ranges as a case study. Surface and subsurface data were integrated to document different structural styles and their corresponding geomorphic expressions. The results highlight the structural styles and their evolution in the context of active Himalayan tectonics.

Summary: This study reveals the paleoclimate during the deposition of the Middle Triassic Tredian Formation using petrographical and geochemical features. The results indicate a chemically immature to sub-mature and dry to semi-arid condition, with sediments originating from the interior of the craton and deposition on the passive margin of the Indian Plate.

Summary: This study provides a detailed elemental profile of Toot oilfield in Pakistan using instrumental neutron activation analysis. The concentrations of major, minor, and trace elements vary with depth, and surface and depth samples can be differentiated using principal component analysis. The study also examines the presence of radioactive materials in the oil wells and calculates their impact on the environment.

Summary: The Late Permian succession in the Upper Indus Basin of northeastern Pakistan, characterized by the Zaluch Group, shows promising reservoir properties in the Chhidru Formation. Petrographic evaluation using SEM, EDX, and XRD techniques reveals varying porosity types and percentages across different facies within the formation. Despite diagenetic processes impacting primary porosity, secondary porosity has been created through dissolution and fracturing.

Summary: This study assessed the coastline change and its impacts on the Indus Delta, using satellite imagery and statistical analysis. The results showed that the North-West Karachi experienced accretion and increased mangrove cover, while the Western Delta and Middle West Delta experienced massive erosion and substantial mangrove cover loss. The analysis also revealed the importance of addressing vulnerabilities and implementing nature-based solutions to revive the Delta in the face of reduced sediment flow and climate change.

Summary: This study investigated the hydrocarbon potential, thermal maturity, and ranking of coal from the Salt Range in Pakistan. The results show that the coal is of low rank with low moisture content and high volatile material. The coal is thermally immature and has low carbon contents. It is dominated by type II organic matter and is an excellent source rock with oil-prone and gas-prone characteristics.

Summary: The study focuses on the biogeochemistry of organic carbon in the Indus River, Indus Delta, and coastal waters, examining the concentrations and fluxes of dissolved organic carbon (DOC) and particulate organic carbon (POC). The research shows seasonal variations of POC in creeks, with the main sources identified as mangrove litter and benthic microalgae. Isotopic studies reveal mangroves significantly contribute to DOC and POC in the Indus Deltaic creeks.
