Spotlight: Anadarko’s Completion Transport System — ACTS
Anadarko’s Completion Transport System (ACTS) is an award-winning example of centralizing storage and staging activities. Anadarko creates temporary staging sites on existing well pad locations to treat completion/flowback fluids. The company then moves filtered completion fluids by temporary pipelines directly to other well pads for completion activities.
Prior to using ACTS, a typical four-well pad would require:
This completion scenario posed logistical challenges due to overcrowding. Instead of responding with larger disturbance areas at the multi-well pads to accommodate completion fluid tanks and associated equipment, Anadarko instituted ACTS.
ACTS uses refurbished pits as staging areas for completion fluids.
Drilling fluid is evaporated or hauled to disposal after conclusion of drilling operations
Fill dirt is mixed with remaining drilling mud solids and cuttings from the large end of the pit and moved to the small end of the pit
Pit is re-lined with impermeable barrier to prevent infiltration
|Temporary Surface Lines|
Lines are hand-placed along existing roads and/or right-of-way
Lines are visually inspected and pressure tested
Lines are flushed with fresh water and then purged with compressed air into a truck or to the reserve pit before they are moved.
For more information on ACTS, see the presentation (ACTS: Anadarko Completion Transport System) given by Jeff Dufresne at the workshop, Opportunities and Obstacles to Reducing the Environmental Footprint of Natural Gas Development in the Uintah Basin in October 2010.
Anadarko received the Interstate Oil and Gas Compact Commission Chairman's Stewardship Award in 2010 for ACTS. For information on this and other Anadarko awards, go to the BMP Search page and include +award +anadarko in the Keywords panel.
