Nazarbayev University, Nur-Sultan, Kazakhstanhttp://nur.nu.edu.kz/handle/123456789/6129When it comes to managing waterflooding activities in a field, interwell connection is a critical factor to consider. This parameter is important to be analyzed to determine the distribution of injected fluids in a reservoir and toward the producing wells. The Capacitance-Resistance Model (CRM), which was first developed in the early 2000s, is an analytical technique for waterflooding modeling and optimization. Producing and injecting data are utilized as input in order to calculate the material balance and estimate factors such as the interwell connectivity of the wells. This study was focused on the accuracy of applying the Capacitance-Resistance Model to estimate the interwell connectivity and compare it with results obtained by tracer flooding tests. A technique like this allows for a more accurate assessment of the link between the wells as well as a more cost-effective and timely choice on the next field development stages. Data from tracer tests and CRM were used to determine connectivity values for synthetic and actual fields, which were then examined and compared. CRM was capable of modeling floods and estimating production in these areas with a level of accuracy that was acceptable. In order to increase the accuracy of the CRM technique used to compute the interwell connection between injector/producer pairs, other parameters such as well spacing and fluid loss during the injection were taken into consideration. CRM, according to our findings, may be used to provide a rapid approximation of interwell connection under specific assumptions, and it is suggested as a substitute for tracer flooding analysis in situations when the tracer test is either not feasible or too costly to do.enAttribution-NonCommercial-ShareAlike 3.0 United StatesCRMType of access: EmbargoCapacitance-Resistance ModelInterwell ConnectivityTracer FloodingMaster's thesis
