abstract = {Described herein is an empirical model to estimate inflow performance relationship (IPR) of fishbone wells. A reservoir simulation model is formulated and initial values for a plurality of reservoir and fishbone well parameters are assigned. IPR curves are generated by simulating the formulated reservoir model for a predetermined number of iterations. Each simulation iteration has a unique value of bottom-hole flowing pressure. Sensitivity analysis is performed based on the generated IPR curves by sequentially changing the values of the plurality of fishbone well parameters. Further, regression analysis is performed based on the sensitivity analysis in order to determine an empirical model that estimates the IPR of the fishbone well. The empirical model is determined as a function of a number of multilateral branches of the fishbone well.},

abstract = {Oil recovery processes from carbonate or sandstone reservoirs. With a carbonate reservoir, the reservoir is initially flooded with a fluid such as seawater. Then the same fluid containing a plurality of citric acid-filled microcapsules is injected into the reservoir. These microcapsules are left to incubate in the reservoir, which will then infiltrate the rock formations, degrade by heat and release the encapsulated citric acid. The released citric acid reacts with the carbonate rocks to produce CO2 in situ, which causes oil trapped in the rock formations to swell, reduce in viscosity, and move towards a nearby production well. For a sandstone reservoir, calcium carbonate can be also encapsulated with the citric acid for CO2 generation at the reservoir.},

In addition, the system can tolerate salts much better than classical surfactants. This system will be appropriate for wellbores having high temperature (>85° C.) with harsh environmental conditions.},

abstract = {A method for assessing an inflow performance relationship for a horizontal well in heterogeneous solution gas drives reservoirs. A commercial simulator Eclipse is utilized to develop IPRs for horizontal wells producing oil from solution gas drive reservoirs. Firstly, a simulation model is developed where a base case is considered with typical rock, fluid, and reservoir properties using a black oil model. Dimensionless IPR curves are generated by obtaining a set of points relating to flowing bottom-hole pressures to oil production rates. The effects of several reservoir and fluid properties such as bubblepoint pressure, oil gravity, residual oil saturation, critical gas saturation, initial water saturation, porosity, and absolute permeabilities on the calculated curves are investigated. A new single empirical IPR model is obtained for horizontal wells producing oil from heterogeneous solution gas drive reservoirs suitable for systems with different reservoir permeability.},

The resulting waveforms can have a signal-to-noise ratio significantly greater than the signal-to-noise ratio of the original waveforms, due to the two stacking operations following each redatuming step.},
