Better-quality Late Miocene globigerinid sand reservoirs in the Madura Straits (Oyong and Maleo fields), offshore Indonesia, occur as bedded stacked gully-fill deposits (internalites) in depositional sweet-spots focused by submarine gully backflow sand thicks, within the wave-reworked (deepwater swash) zones on the upper slope and outer platform. Isotopic analysis shows that post-depositional alteration is minimal.
These gullied and channelled globigerinid sand bodies (internalite deposits) are seismically resolvable and cut into bed-parallel sandy slope-parallel reflectors. This signature indicates regions where internal-wave orbitals and swash zones intersected the carbonate slope south of the Madura Ridge (water depths ≈100-300m). It gives a new exploration paradigm.
Study of core and outcrops in the Dallol region of the Danakhil depression, Ethiopia, shows the complexity of potash minerals and their alteration. Previous work failed to differentiate
Integration of FMI with conventional wireline-derived mineralogy is used to characterise the Bitter Springs evaporites (and equivalents) atop the main thrust level. A new model was constructed that redefines the timing and nature of the anhydrite levels across much of the basin.
