Production Rate Analysis of Cold Heavy Oil Production Wells
The objective of the study presented in this paper is to investigate the production rate behavior of Cold Heavy Oil Production (CHOP) wells. In CHOP, foamy oil flows in the form of a continuous foam and appears to have a high compressibility, high critical gas saturation, and low gas mobility. Wormholes dynamically grow, accompanied by tremendous sand production. In this study, a comprehensive model has been developed to simulate the production rate behavior of CHOP wells, accounting for pressure- dependent apparent viscosity of foamy oil, pressure- dependent compressibility, and dynamic wormhole growth Based on the proposed model, production profiles were analyzed to understand dynamic wormhole growth and predict the CHOP well performance. The results obtained from this work will help in determining the infill location and well spacing in pool development, the optimization of a single well production system, and the applications of post-cold technologies.
