Abstract: Methods produce hydrocarbons from an unconventional reservoir using a number of sidetrack lateral wells. A first of the lateral wells is drilled and produced before being closed for drilling of a subsequent lateral well. Drilling and production from such horizontal laterals alternates between first and second mother wellbores. One mother wellbore thereby undergoes drilling and completion while the other mother wellbore is in production.
