Minimize ROC levels and waste volumes, and decrease final disposal costs
Minimize ROC levels and waste volumes, and decrease final disposal costs for a 16-well drilling program
Integrated BaraG-Force™ VacVCD system, which provides:
An operator in the Denver-Julesburg Basin wanted to minimize the volume of retained oil on cuttings (ROC) in oil-based mud (OBM), along with the total volume of treated cuttings requiring disposal. Inefficient drying caused excessive diesel consumption and higher costs for transporting the treated cuttings from location to the disposal site.
The cuttings hopper was loaded manually via augers, slowing the process and increasing safety risks and the potential for spills.
The Baroid team recommended installing the BaraG-Force™ VacVCD (vertical cuttings dryer) system to help minimize ROC levels and waste volumes, which would then help decrease final disposal costs.
The integrated, fully enclosed system combines a proven pneumatic transfer system and an efficient VCD design in a single, modular package, and its small footprint allows for flexible placement at the rigsite.
The system relies on vacuum feed instead of augers, so the delivery of cuttings from the shaker remains continuous. This consistent feed stream helps improve retention and maximize operational efficiency. By comparison, manual loading can cause a dry buildup that leads to packoffs below the hopper.
The dry cuttings produced by the BaraG-Force VacVCD unit exhibited a significantly lower ROC value and helped the operator maintain a much cleaner location. Comparing two rigs drilling identical wells, the rig using drying shakers achieved an ROC of 17.4 percent by weight. The rig equipped with the BaraG-Force VacVCD system achieved an ROC of 4 percent by weight. This significant decrease in ROC helped the operator save an estimated USD 18,350 per well,
