Design of Horizontal Well Thermal Recovery in Ngl Thin Super-heavy Oil Reservoirs in Cao 20 Block

Cao 20 block is a structural - lithologic super - heavy oil reservoir with edge water. In viewing of that the non-producing oil layers in the western part are 6 - 8m thick and are significantly influenced by edge water and the high water cut zone in the eastern part, horizontal wells are used to perform thermal recovery and production parameters of the horizontal wells are optimized. Single well daily output peaks at 40t and average annual production of single well is over 5000t.
