2014 Petroleum Industry Spill Statistics

May 12, 2015

Manitoba’s Upstream Petroleum Industry 2014 Spill Statistics and Report

Manitoba’s petroleum exploration and production industry in 2014 recorded 96 spills which is a 23.8% decrease in the number of spills that occurred in 2013. This is a 10.3% increase over the 5 year average of 87. The total volume of these spills is 1616.8 m3; a 74% increase over the 5 year average of 927.52 m3.  Average spill size in 2014 is 16.8 m3, a 62.5% increase from the 5 year average.

Figures accompanying this report show spill trends for the past 25 years. The number and volume of spills occurring each year over the last decade has generally decreased (Figure 1, 2). Yearly average spill size is seen in Figure 3. Figure 4 shows the percentage of total production spilled; 0.005% in 2012. Industry produced about 16.1 million m3 of fluid.  Of this 2.9 million m3 was crude oil and 13.2 million m3 was salt water. 

Wellhead leaks accounted for 34% of the spilled volume in 2014, tanks resulted in 19%, pipeline/flowline breaks were responsible for 18%, and batteries equipment failure for 18% of the spills. Trucking accounted for the remaining 6% of the spilled volume and other 5%.

In 2014, 35% of the spills occurred in the 1st quarter, 27% in the 2nd quarter, 15% in the third quarter, and 23% in the 4th quarter. 

Spills in 2014 affected 9.65 hectares of land.  Off lease spills or spills that affected agricultural land accounted for 67% of the volume of spills and affected 7.8 hectares of land.  In 2014, about 88.8% of volume spilled was recovered during clean-up operations. 

When a spill occurs, a company is required to contact the Petroleum Branch within 24 hours.  This allows the Branch the opportunity to inspect the spill site and clean-up operations.  When a spill occurs off lease land the site is typically entered into the Branch’s rehabilitation monitoring program.  There were 128 rehabilitation sites entered into the program in 2014. 

A typical spill clean up involves a vacuum truck collecting all the freestanding fluid, which is then trucked to an approved treatment and disposal facility.  The spill site is usually treated with gypsum and calcium nitrate to encourage biodegradation of oil and leaching of salts.  The rate of application of these amendments varies according to the degree of contamination.  Where onsite treatment is not feasible, the contaminated soil is recovered and disposed of at an approved facility. 

If you have any questions on this report please contact Lorne Barsness, Senior Petroleum Inspector at (204) 673-2472.
