The operator designed the StackFRAC system to segment the 2,600 ft lateral into seven stages. The completion system was installed to a measured depth of 7,480 ft without issue. With the use of coiled tubing, all seven stages were opened and allowed to produce. The well was produced for 6 months to establish a baseline for unstimulated production potential.
Following the 6-month production period, coiled tubing was used to close all but the first stage of the completion system. The operator stimulated this stage, ran into the hole with coiled tubing to close the DC FracPORT sleeve, pressure tested the system to ensure it was closed, and then opened the next sleeve to allow for stimulation. This process was repeated until all seven stages were stimulated.
After stimulation, all seven stages were opened with a service rig for production. The well was then flowed back, producing 10 times more BOE than the previously completed vertical wells. Even with the coiled tubing operations, the total stimulation time was only 30 hours and was done on time and on budget. Since this was the operator’s first attempt at a horizontal well for the purpose of exploration, the decision to move forward in the Mancos was dependent upon the cost, time to complete, and production results of this well. Because the operation and results were a success, the operator plans to develop its Mancos formation assets using the StackFRAC system.
