#Rtc otc engineering calculator simulator#
The overall project was divided into three main categories: (1) advanced reservoir simulation techniques for modeling nonconventional wells (2) improved techniques for computing well productivity (for use in reservoir engineering calculations) and for coupling the well to the simulator (which includes the accurate calculation of well index and the modeling of multiphase flow in the wellbore) and (3) accurate approaches to account for the effects of reservoir heterogeneity and for the optimization of nonconventional well deployment. Our research under this five year project addressed all of the key areas indicated above. This more » simulator must be sufficiently general and robust and must in addition be linked to a sophisticated well model. In order to model and optimize nonconventional wells in different settings, it is essential that the tools be implemented into a general reservoir simulator. In addition, the impact of geological and engineering uncertainty (e.g., valve reliability) has not been previously considered. For example, the optimal use of downhole inflow control devices has not been addressed for practical problems. A number of new issues arise in the modeling and optimization of nonconventional wells. This is likely due to inadequacies in some of the reservoir engineering and reservoir simulation tools used to model and optimize nonconventional well performance. However, predictions of nonconventional well performance are often inaccurate.
Because nonconventional wells can be very expensive to drill, complete and instrument, it is important to be able to optimize their deployment, which requires the accurate prediction of their performance.
The use of nonconventional wells instrumented with downhole inflow control devices allows for even greater flexibility in production. These wells are able to contact larger regions of the reservoir than conventional wells and can also be used to target isolated hydrocarbon accumulations. Nonconventional wells, which include horizontal, deviated, multilateral and ''smart'' wells, offer great potential for the efficient management of oil and gas reservoirs.
