.... For a miscible flood, to be an efficient process for a given reservoir, several conditions must be satisfied; given that the incremental oil recovery is largely dependent on reservoir properties and fluid characteristic. Experiences gained from a miscible rich HC-WAG project in Abu Dhabi, implemented since 2006...

.... The original Koval work also provides a means of estimating oil recovery for miscible floods but it works if a single front displacement is assumed. This could be a limitation for tertiary floods where an oil bank forms and displacement has two fronts ( Figure 1 ). This work also accounts for the interactions...

.... The relative permeability is the connecting link between the phase behavioral and transport properties of the system. Relative permeability is an important petrophysical parameter, as well as a critical input parameter in predictive simulation of miscible floods. WAG Ratio, Slug Size and Tapering...

...; mercury injection; 3-D porosity distribution; oilfloods and waterfloods on cleaned samples; and 3-D flow imaging of miscible floods, oilfloods, and waterfloods on restored state samples. The 3-D Computed Tomography (CT) images allowed us to understand the reasons for decrease in oil saturation observed...

... undersaturated oil. A miscible flood was initiated in 1989 immediately following delineation drilling. The numerical model was constructed using the most up-to-date geological, geophysical, and petrophysical data. Surface facilities were incorporated into the model, through the use of individual well test...

... ABSTRACT This paper describes the design of a full-field vertical tertiary hydrocarbon miscible flood (HCMF) in the Acheson D-3A pool. Subsequent design changes based on secondary HCMF performance, and early production history are presented. Monitoring and operation of the HCMF are also...

... with emphasis on the type and quality of log and core data obtained, six years of primary production, followed by a gravity stable vertical waterflood, and, 30 years later, the design and implementation of a gravity stable secondary hydrocarbon miscible flood HCMF. The secondary hydrocarbon miscible flood...

.... This resulted in final development drilling being conducted during the miscible flood facility installation. Development was started by implementing an extensive seismic acquisition and pulse testing/pressure transient program to determine reservoir boundaries and continuity. The ultimate well density, pattern...

... Abstract The Rainbow Keg River AA pool is a dolomitized carbonate reservoir in a mature stage of a vertical hydrocarbon miscible flood. The long history of enhanced recovery, plus the fact that the pool had not produced according to initial expectations, formed an ideal framework...

... and capillarity in the base state, Equation (21) , none of the qualitative features associated with the B-L base state are seen. This is because the steady state solution does not have a spreading transition zone. Instead the results are identical to a miscible flood, with some level of dispersion. Buckley...

... ABSTRACT The early performance of Stage 1 of a large three-stage hydrocarbon miscible flood project at the Mitsue field, Alberta, Canada, is presented. The project area was almost completely waterflooded before project initiation. Hence, this is largely a tertiary oil recovery project...

... to naturally incorporate noise. Solvent (miscible) flood is examined in detail. Scaling of breakthrough recovery, and its dependence on mobility ratio, M, is determined for .1 < M < 1000. Unstable floods self-stabilize on sufficiently fine grids; the cross-over to stable flow depends upon M...

... ABSTRACT The source of carbon dioxide (CO 2 ) breakthrough is masked for production wells in the interior of a CO 2 miscible flood. An inexpensive, safe, and continuous tracer is desirable to monitor the flood performance. * Halogen compounds (specifically halocarbon-11, halocarbon-12...

... ABSTRACT A tertiary extension of the existing secondary hydrocarbon miscible flood in the Wizard Lake D-3A Pool was implemented in October, 1983. The extension will result in the oil-water contact being lowered 22.6 meters (74.1 feet) to allow miscible displacement of the residual oil...

The carbonates displayed more variable and larger axial dispersion than the sandstones. First contact and CO 2 miscible flooding...

... Abstract A successful miscible flood was initiated during 1966 in the Camp Sand Unit, North Haynesville Field, Claiborne Parish, Louisiana. The Camp Sand Unit is about 3.5 miles (5.6 km) long and 1 mile (1.6 km) wide. Injection of a slug of enriched gas was followed by a buffer of natural gas...
