2019 LBCG Onshore well site facilities summit

American Business Conferences event hears from Oxy’s digital oilfield, Agar Corp on multi-phase metering on every well and Hy-Bon EDI on vapor recovery and eliminating flaring.

digital oilfield work in the Denver-Julesburg Basin, Colorado. Here Oxy operates some 1800 producers, gathering 70 million data points per day from 140K real time tags. The team has developed digital oilfield workflows around Petex’ Integrated Visualization Manager (IVM), now used across the company. One use case addresses lease automatic custody transfer pressure swing surveillance arising from paraffin plugs that cause unmeasurable production deferment. The solution involved ‘breaking down silos’ and combining workflows such that everyone gets to see the same data. The system provides an in-depth understanding of production losses, analyzing impacts from perforations to sales. Another digital oilfield development automates pigging schedules, previously managed in multiple spreadsheets. Now data is captured automatically, linking dynamic and static data and providing roll-up summaries. Operators can record pigging operations in real time from their phones with increased efficiency and fewer errors. While the DoF program has produced few single large wins, the incremental 5 to 50 bopd gains ‘soon add up’.

Agar Corp multi-phase metering on every well

David Farchy presented Agar Corp.’s multi-phase metering solutions (MPFM). Today, the separator is still the standard equipment for assessing gas/oil/water composition. Agar wants to change this such that every well has a low cost MPFM. Agar’s systems have been deployed in the Eagle Ford shale, the Permian basin and in and Venezuela. MPFMs are networked, via the cloud, where ‘semi empirical self-learning AI algorithms’ correct and calibrate MPFM data continuously. Agar’s digital platform provides a visualization dashboard to web and mobile endpoints, enabling surveillance at the well, well-pad, field or reservoir level.

Hy-Bon EDI on vapor recovery and eliminating flaring

Jeff Voorhis, from Cimmaron Energy unit Hy-Bon EDI, advocated the use of vapor recovery units/towers (VRU/VRT) to eliminate flaring, mitigate volatile emissions and provide an additional revenue source. A site currently flaring 55MSCFD could be earning $132,000 per year (at a possibly optimistic $4/MSCF) and providing a 9 month payback on a $100,000 capex. VRTs need to be engineered for proper retention time to allow gas to separate and to avoid liquid traps in gas vapor piping to the VRU. Voorhis warned that the Texas regulator’s stance on flaring is shifting against the practice*. The Texas commission on environmental quality is also upping its inspection régime, with flyovers of oil and gas production sites with FLIR Cameras to spot fugitive emissions. Back in 21015, Noble Energy’s DJ Basin unit was fined some $13.5 million in civil penalties and another $60 million ‘to support environmental mitigation projects’. Noble agreed to upgrade its equipment to reduce emissions, with the work expected to be complete in 2019.

Next year’s Wellsite Facilities event is scheduled for 15-17 September 2020 in Houston.
