Drilling more than one drainhole from a primary borehole is increasingly common. Applications include heavy-oil deposits, naturally fractured or layered formations and fields with bypassed hydrocarbons resulting from distinct reservoir compartments or partial reserve depletion. Strength, sand exclusion and pressure integrity at junctions between lateral branches and a main wellbore are crucial to completion success. We present results from test wells and field installations in North and South America, Africa and Southeast Asia.
