Finally, the simulator is applied to an assisted history matching example using surface subsidence data to illustrate its...

... technology, but it involves large operational costs. On the Norwegian continental shelf (NCS), another geophysical method has been in use for two decades: 4D gravity and subsidence surveys, with a cost typically 15% of that of seismic surveys. Field cases show that, in some cases, this technology provides...

...Neural Networks in Oil and Gas Prediction of subsidence can be done in two ways based on measured parameters. First approach is to develop models based on physics and then use model defined relationship to estimate function of interest. This approach is developed based on simple models...

... Abstract Discovered in 2002, Perdido is a Gulf of Mexico frontier ultra-deepwater development, and its success has been heavily dependent on several technologies: 4-D seismic for waterflood management, PMTs (pressure monitoring transducers) for subsidence monitoring, MPD (managed pressure...

... be used to give back something to New Orleans that it has been steadily losing for centuries – its elevation. The subsidence of New Orleans is principally due to natural dewatering and decomposition of the fluviodeltaic sediments underlying the city. As the sediments compact, the city sinks lower...

... Abstract Extraction of oil and gas can cause reduction in pore pressure, occasionally resulting - in shallow reservoirs - in subsequent compaction that forms a surface subsidence bowl. In the last 10 years, there has been over 10 feet of subsidence in parts of the Lost Hills diatomite oil field...

..., there are large uncertainties in both the fault transmissibilities and the strength of the connected aquifer. Consequently, there is a possibility of undepleted compartments in the reservoir. Pressure depletion due to gas production results in compaction of the reservoir sandstones leading to surface subsidence...

... rocks that forms where coal has burned previously, (2) the primary driving force for air flow is the density-driven flow of hot combustion product gases through surface fissures that form as a result of subsidence as the coal burns, and (3) CO 2 injected into the air flow zone is drawn by the density...

This paper demonstrates that more information can be extracted from surface deformation measurements by inverting the surface deformation for the volumetric deformation at the reservoir level, so the areal distribution...

... Then, the overall reservoir compaction is given by Eq.3 Δ p = ∫ 0 H C m Δ p ( z ) d z Abstract Oil or gas production causes reservoir depletion. It induces reservoir compaction and subsidence and earth surface lateral movement. Gas and oil are found...

... Abstract Normally, the inverse problem to map reservoir compaction from surface subsidence is an ill-conditioned system since the subsidence bowl gradually changes its curvature, hence, the boundary of pressure depleted area cannot be clearly identified from subsidence bowl. However...

The calculated subsidence volumes are thought to be close to the subsidence at the tops of the reservoirs. The images show that the rate of subsidence has decreased in some parts...

... Abstract Over 7.8 meters of seafloor subsidence has occurred at the Ekofisk Field in the Norwegian sector of the North Sea since the start of production in 1971. Full field water injection was initiated at Ekofisk on a limited scale in 1987. The surface subsidence is a result of reservoir...
