Highmark Energy Operating is the operator of the Tinsley field in Yazoo County — one of the most historically significant Mississippi oilfields. Highmark is the same operator that runs the Conroe Field Unit in Texas (Montgomery County) and is a serial acquirer of Denbury legacy CO2/waterflood assets across both states. Mineral owners with positions on either Tinsley (MS) or Conroe (TX) deal with the same operator entity.
