anticipate moving the rig to Upton County and drilling 10-11 wells. Consistent with previously released guidance, we anticipate drilling 16 gross / 14.8 net operated wells and spudding an additional 5 gross / 3.7 net operated wells during 2021. Additionally, we are focused on efficiently integrating the recently acquired IRM assets into our operations. As a result of the IRM Acquisition, we added 43,400 additional net acres in the Midland Basin of which 99% is operated and 1% is non-operated, as well as adding 70 potential gross horizontal drilling locations on core acreage located in Midland and Ector counties. We recorded impairments in 2020 as follows: (1) Impairments in unproved properties resulting from acreage deemed expired (not planned to be renewed).
