Interplays Between Mudstone Diagenesis and Bulk Rock Properties

Presented by Claudio Delle Piane

Abstract

Prediction of rock properties distribution in sedimentary basins requires a detailed understanding of the links between depositional environment, post depositional maturation and diagenetic pathways based on observations linking the nano- to the well- and basin-scales. These observations are crucial to build a process-based understanding of factors affecting reservoir quality in space and time and to inform the most appropriate modelling scenarios for rock properties prediction.

Diagenetic studies of unconventional shale reservoirs are, to date, less documented than their conventional reservoir counterparts and the links between the chemical and physical effects of diagenesis (i.e. cementation and compaction) and geo-mechanical and petrophysical properties of fine-grained unconventional reservoirs remain poorly documented.

Nevertheless, interest in mudstone diagenesis and reservoir quality prediction has flourished in the past decade stimulated by the boom in hydrocarbon production from shale reservoirs in North America, highlighting how an advanced understanding of diagenesis is critical to improve our ability to efficiently extract resources from these sediments.

This presentation will discuss diagenetic and thermal maturation pathways identified in the mineral and organic components and their impacts on rock properties, highlighting similarities and differences in key examples from productive or prospective organic-rich mudstone from North America, China, Western Australia and the Northern Territory. While the variations in rock properties can be extreme and predicting the nature, timing and products of mudstone diagenesis remains challenging due the remarkable variety in composition and sedimentary structures characterizing these sediments, a good understanding of the impact of typical geological processes will significantly aid in interpreting exploration and production data for these reservoirs.
