Stage System failure, not good In late 2016 and early 2017, Blackbird drilled and completed its 102/2-20, 3-28 and 2-20/11-9 Pipestone wells (the "Wells") using the Stage Bowhead II fracturing system (the "Stage System"). The 102/2-20 well began production and clean-up on February 4, 2017 and was shut-in due to a third-party plant closure on February 12, 2017. After being shut-in for approximately 29 days, the 102/2-20 well resumed production and clean-up on March 13, 2017. During this secondary period of clean-up and the production of natural gas and condensate, in late April, 2017 it was determined that the 102/2-20 well was not producing at levels consistent with management's expectation.
Thereafter, Blackbird performed a camera run within the wellbore in order to determine the reason for the 102/2-20 well's production level. After successful collet engagement and fracturing of the initial stages of the wellbore, the camera run indicated that erosion damage to the landing shoulder of the valve profile prevented proper collet engagement and full sleeve opening in the later stages of the wellbore.
Subsequent to the 102/2-20 analysis, Blackbird performed a similar camera run in its 3-28 well, which has not yet been tied-in or production tested. The results of this camera run confirmed similar metal fatigue, erosion, collet engagement and sleeve opening issues as in the 102/2-20 well.
