This paper presents the PDVSA experience of multilateral wells planning and construction in a heavy crude oil reservoir. In the planning phase, multilateral technology shown to improve the project economics, based on the construction of 12 multilateral wells. Geology, drilling, completion, and workover aspects were evaluated for selecting the most appropriate junction level. Levels 3 and 4 were fully compared. Level 4 junction was selected after the analysis. So far, PDVSA has constructed 9 MLT wells in Bare field. The production results were as planned and the final economics of the project was better than the estimated values. This paper also presents the learned lessons during well operations and concludes that multilateral technology constitutes an economic alternative for the exploitation of this field. Also, this experience contributed to shape the process required for adapting and transferring new technologies in PDVSA drilling operations.
