Can Data Historians Help Curb Spills From Saltwater Waste in the Bakken?

I am very excited to announce the first in a series of guest posts from different employees here at Canary Labs. Information Solutions Consultant, Shawn Ebersole, writes about an event that happened very recently in the Oil and Gas industry:

"I saw in the news yesterday that in North Dakota 1 million gallons of saltwater, the equivalent of 24,000 barrels, leaked from a pipeline.  This caused untold damage to surrounding vegetation, and much worse, the contamination of Bear Den Bay. Bear Den Bay leads to Lake Sakakawea, which is the source of drinking water for the Fort Berthold Indian Reservation. Fortunately, officials believe the drinking water was not affected, but this event got me thinking about how the oil and gas industry can do a better job in preventing this from happening. A big way to prevent this would be the use of a process data historian with real-time and historical trending.

Transporting liquids and gases through pipelines is a very
efficient way to move large quantities of substances from
one place to another.

Before getting into how to use a data historian to monitor saltwater pipelines, it is helpful to understand more about the type of saltwater in the pipelines.  Saltwater is a byproduct that accompanies oil and gas as it is harvested from a well. This type of saltwater is 10 to 30 times saltier than seawater, so if leaked or spilled from a pipeline, it poses a high environmental risk to soil, plants and freshwater resources.

Careful means are taken to properly dispose of this type of saltwater, but unfortunately spills like I saw in the news, have been happening frequently in North Dakota. The reason for the increased number of spills is relative to the growth of oil production in the Bakken.  As of November 2013, North Dakota had 515 saltwater disposal wells and 2,127 saltwater pipelines.  

A bill backed by the Northwest Landowners Association in 2013 would have required the use of flow meters and cutoff switches on all gas and liquid transmission lines, including saltwater pipelines; the bill was voted down 86-4. The opponents of the bill claimed the requirements were too complex and expensive. Further legislation surrounding saltwater pipelines continues to be debated as the subject is becoming a focal point during the race for the Agricultural Commissioner.

After understanding the background of the saltwater waste situation in the Bakken, both environmentally and politically, I feel there will be a movement towards closer monitoring of the saltwater waste pipelines. When this happens the ability to store, visualize and report on data obtained from the flow meters, cutoff switches, etc…will be crucial, and it will be important for the oil and gas companies operating in the Bakken to have a high performing data historian."
