Oilfield Sandstone Cementation Micro-Geochemical Tracers

Project data from the British Geological Survey investigates mineral cementation in hydrocarbon reservoir sandstones, which can alter porosity by 50% and permeability by 105. The research combines micro-isotopic and micro-geochemical composition analysis from cements with conservative tracers and palaeopressures to calibrate basin-scale geological models.

Use Cases

• Analyze micro-isotopic composition within cements to reconstruct detailed zonation records of palaeo-hydrogeology.
• Combine conservative tracers with palaeopressures from fluid inclusions to resolve conflicting interpretations of cementation processes.
• Use micro-geochemical composition data to calibrate blocks in basin-scale computer models for reservoir quality prediction.
• Apply statistically based sampling on micro-scale analytical data for reliable up-scaling to basin architecture models.

Strengths

• Research quantifies significant potential impacts, with cementation processes capable of changing porosity by 50% and permeability by 105.
• Project integrates multiple advanced analytical methods, including ion and laser microbeam instruments for natural isotopic tracers.
• Data originates from the authoritative British Geological Survey (BGS) and is tagged for integration with geological models.

Limitations

• Dataset specifics are unavailable; input lacks concrete details on rows, columns, sample data, or file formats.
• The description is project-focused, not data-focused, making the actual available data structure and volume unknown.
