Use of CO2 /steam to enhance floods in horizontal wellbores

Abstract: A method to enhance steam flooding where at least two horizontal wellbores are utilized. Carbon dioxide is injected into a lower perforated horizontal wellbore. Once sufficient carbon dioxide has been injected into the formation, steam is injected through the lower horizontal wellbore. The steam displaces the carbon dioxide into the formation where it contacts and mixes with hydrocarbonaceous fluids. Steam causes the carbon dioxide to expand, thereby providing for a better sweep of the formation. Steam injection is ceased and liquid carbon dioxide injection again is commenced. Afterwards, steam is injected again into the formation. This sequence is continued until it becomes uneconomical to produce hydrocarbonaceous fluids from an upper horizontal wellbore. Hydrocarbon displacement efficiencies are enhanced when hydrocarbons are produced into the upper horizontal wellbore due to viscosity and density differences.

Kinetics of catalytic cracking selectivity in fixed, moving, and fluid bed reactors

Abstract: A kinetic mathematical model of catalytic cracking is described which accounts for conversion and gasoline yield in isothermal fixed, moving, and fluid bed reactors The model has been tested and verified by using laboratory moving bed data with a commercial gas oil and catalyst It is shown that under certain conditions, the selectivity behavior and maximum gasoline yield of fixed, fluid, and moving bed reactors will be identical Maximum gasoline yield is defined in terms of both the kinetic parameters and the process variables for fixed, moving, and fluid bed reactors

Disposal of produced formation fines during oil recovery

Abstract: Recovered formation fines are pumped in slurry form into an injection well during an enhanced oil recovery process e.g. a steam flood. Said injection can be done incrementally in stages in conjunction with said process. Said fines improve the sweep efficiency of the injected medium. This method is also beneficial where steam breakthrough has occurred since the breakthrough path is in a fluid or semi-solid state thereby allowing the fines slurry to be injected.
