Volcanic stratigraphy from ditch cutting analysis

Abstract

Ditch cuttings from wells penetrating flood basalt sequences provide the most commonly available lithological data from which an assessment of the volcanic stratigraphy at a specific location can be made. Many advances in recent years have been made in regards the geophysical response of volcanic facies from down-hole tools however, a similar development in regards to ditch cutting analysis and classification is not apparent. We propose a fresh approach in an attempt to quantify some of the accuracy issues commonly attributed to cuttings. The approach presented comprises a simple analysis workflow and non-genetic classification system that aims to encompass broadly the expected lithologies found in a flood basalt volcanic succession. From this classification system a simplified log output can be produced and subsequently interpreted. The major benefits include a simplistic transparent approach, easily integrated into the real time drilling workflow along with a visual output again easily integrated with well logs and any other stratigraphically constrained information. A move towards a unified approach is required before regional comparisons and synthesis can be undertaken with confidence.
