Two wells extending more than 2 miles were drilled from Platform Irene in the Pt Pedernales field, offshore California. These wells are the two longest extended-reach wells on the U.S. west coast. Although several wells around the world have been drilled beyond two miles, none extend at such shallow true vertical depths (TVD's) as the two from Platform Irene. The average angles from rotary table to total depth (TD) for Platform Irene Wells A-16 and A-17 are 70.9{degrees} and 68.2{degrees}, respectively. This paper presents the concepts of a negative-weight well and drag-risk analysis, focusing on the innovative technology used to drill and complete a high-dray well. The successful drilling an completion of these wells will allow recovery of millions of barrels of oil originally expected to be produced from a second platform.
