Tight oil production has become significant over the last decade with the success of horizontal drilling and multistage hydraulic fracturing. However, the recovery factor from this process is very low, and no standard secondary recovery method exists after primary depletion. This talk envisions a new secondary recovery method: to use existing hydraulic fractures in a horizontal well as gas injection and oil production sites to conduct gas flooding within a single well. Key aspects are defined and examined, showing promising results. Inter-Fracture flooding may possibly become a standard secondary recovery technique for tight oil reservoirs and add significant reserves.
