From agua caliente (‘hot water’) to aceite caliente! (‘hot oil!’)

Neil Hodgson, Karyna Rodriguez, Dennys Uyen, Searcher; Julia Davies and Lauren Found, Discover Geoscience
Please note: due to online file size limits we have had to scale down the resolution of this foldout. You can find the higher resolution version on pp42-46 of GEO ExPro…

Improving 3D images

Andrew Long, PGS Technology, Perth, Australia and Constantine Tsingas, PGS Geophysical, London, UK.
A deep, structurally complex carbonate reservoir offshore Philippines has been imaged with great clarity and resolution, despite the severely rugose water bottom and stratigraphically complex overburden. This has been accomplished…
