Announcement - Introduction of New Waste Codes
The release of ERCB Directive 047: Requirements for the S-25 Monthly Oilfield Waste Management Facility Statement included the addition of new wastes codes for reporting purposes. The waste codes will affect the reporting requirements for oilfield waste management facilities (Directive 047), as well as, oilfield waste generators reporting their 2009 annual oilfield waste disposition report in accordance with ERCB Directive 058: Oilfield Waste Management Requirements for the Upstream Petroleum Industry. When the consolidation of Directive 058 is released the waste codes will be added to Table 7.4 Waste Management Table.
Through this announcement, the waste code SWBFLD (Swabbing Fluids) has been replaced with HSPWTR (High Solids Produced Water), which better represents the physical properties of the waste stream.
When low pressure wells are swabbed to remove produced water from the wellbore and no additives/materials (e.g., acids, chemicals, solvents, surfactants/soaps) are introduced during the swabbing activity, the recovered swab fluids are produced water with entrained wellbore fines. If the fines content is too high for disposal of the produced water and fluids are sent to a third party waste management facility for fines separation/processing, the fluids must be tracked and reported using the waste code HSPWTR (high solids produced) and included in the annual oilfield waste disposition report. Should the licensee of the well that generated the fluids have the capability to separate the fines, either on the well site or at the licensee’s production facility to which the well is producing, the resulting fluids must be tracked and reported as produced water through the Petroleum Registry of Alberta and the separated fines must be tracked and reported using the waste code FRMFNS (residual formation fines after treatment or settlement) and included in the annual oilfield waste disposition report.
