... techniques (Hirasaki et al., 2011). Oil recovery is even more challenging in carbonates compared to sandstone reservoirs. Carbonate reservoirs hold more than 60% of the world's oil and 40% of the world's gas reserves. In addition, approximately 70% of the Middle East reserves are held in carbonate reservoirs...

... in the deep water GOM that are interpreted to be hard substrates suitable for benthic organisms. Where deep ocean currents are adequate to wash the fine hemipelagic mud off these carbonates, the latter becomes a clean, suitable substrate for benthic organisms. Unfortunately, 3-D seismic has a vertical sample...

... Abstract Infiltration of shallow soils by naturally occurring hydrocarbons has been documented in several deepwater environments worldwide. The potential for significant soil modification, such as the development of authigenic carbonates and alteration of the generally expected background...

... Abstract MultiBeam Echo Sounder (MBES) bathymetric and backscatter data are used to discriminate the backscatter response of four seafloor features: a carbonate mound, a hydrate mound, a small mud volcano, and pockmarks in the vicinity of the welldocumented Bush Hill seep site. Each...

...), or a thermogenic origin (from a source rock " kitchen??). Whatever its origin, once the methane-enriched fluid reaches the seafloor, it creates a morphology anomaly (crater-like depression), often associated with mineral precipitation, including methane-derived authigenic carbonates. In addition, pockmarks...

... by precipitation of 13 C-depleted Ca-Mg carbonates. Other precipitates such as barite have also been observed in slow-tomoderate flux settings. At the other end of the expulsion spectrum are response features derived from rapid delivery of fluids (including fluidized sediment) and gases to the seafloor. Mud...

... ABSTRACT Stylolites have been reported in basinal, reef, forereef, and backreef carbonates within the Permian Basin of West Texas and southeastern New Mexico. They are described as serrated interfaces between carbonate rock units and are composed of their insoluble residues. Samples...

... and authigenic carbonate formation. Recognizing the characteristics that distinguish these mound types is a fundamental part of evaluating seafloor features and their geohazards potential. This paper contrasts two mound-like features on the upper slope that have salt cores which penetrate to near the modern...

... carbonates. In 1979, Cretaceous and Eocene turbidities became important targets and until 1984, Eocene and Oligoceneturbidities represented 50% of the targets. In 1984, activities were directed towards deepwater and by 1990, Eocene, Oligocene and Miocene turbidities represented 90% of the targets...

The section above the reservoir is a thick sequence of Lower Miocene to recent marine clay stones. The overall development program calls for drilling...

Extensive benthic communities are observed along with broken and tilted blocks of authigenic carbonate. This structure...

... ABSTRACT Since the drilling in January 1987 of the Liuhua 11-1-lA discovery well, six additional wells, four on the primary structure and one each on two satellite structures, have drilled and tested this lower Miocene reservoir carbonate. Deposition of the carbonates took place in isolated...

... carbonates of Lower Cretaceous age. It was not until late in 1979, however, that a far more significant hydrocarbon accumulation was found in the Cenomanian sands of the Vermelha Formation. All four fields produce primarily from Vermelha sands deposited on a trend of structures whose genesis was controlled...
