This study was designed to compare and contrast variations in acid-released (“adsorbed”) light-alkane and aromatic hydrocarbons collected on a detailed grid over Kinsale Head gas field, offshore Ireland (Blocks 48/20, 48/25, and 49/16), with those collected on a regional grid that sampled the North Celtic Sea Basin. This study also tests the limits of acid-released-gas methods with respect to bottom conditions, because extremely sandy bottoms characterize the region.
Statistically significant gas-yield differences between samples collected in the Kinsale Head area and those collected on the regional grid show that near-surface samples reflect gas leaked from the reservoir. Fluorescence intensities collected in the Kinsale Head area outline the extent of reservoired gas.
This study clearly demonstrates that acid-released-gas and fluorescence methods can be applied successfully in difficult sampling conditions and can delineate the productive limits and suggest the nature of production within a reservoir. The methods do not necessarily represent reservoir fluid compositions accurately, however.

Surface Exploration Case Histories: Applications of Geochemistry, Magnetics, and Remote Sensing provides an overview of successful applications of surface exploration methods. Through a series of independent case histories, this volume presents clearly documented evidence that demonstrates how surface exploration methods can significantly reduce exploration risk and finding costs: geochemical, magnetic, and remote sensing. The 19 chapters in this volume reflect the broad scope of applications for these methods: frontier basin reconnaissance, prospect development, prospect evaluation, and field development and production. The case histories span the globe: 1. North America 2. Africa 3. South America 4. Europe 5. Middle East 6. Australia. This book will interest explorationists and managers who seek to get the most out of each exploration dollar.
