HSE & Operational Excellence

Promoting sustainability—pertaining to both production and the environment—is critical

When extracting heavy oil Halliburton ensures that safeguards and procedures are in place to conserve and protect the area's natural resources, primarily its water, as well as limiting the amount of energy required to complete the project. Heavy oil is hard to produce, costly to produce, and takes more energy to produce. We work hard to keep fields viable long after they would experience a steep decline.

In heavy oil projects, producers and service companies alike must meet a vast array of environmental, health and safety standards

Halliburton goes beyond compliance to focus on sustainability in everything we do, striving to leave the places where we work better than we found them. Our goal is to provide products and services that have minimal environmental impact, are safe in their intended use, consume resources efficiently, and can be recycled, re-used or disposed of safely. We have always embraced the responsibility of ensuring that all our technologies meet the highest safety and environmental standards.

When it comes to using water, less is more

Water is arguably Earth's most precious resource. And wherever we work, the public wants to know that their water is safe. As a conservation measure, Halliburton is making huge strides in the effort to better ultilize produced water, flowback treatment water and water from uncommon sources. Conserving fresh water by using less of it, particularly in places where fresh water is in short supply, requires innovative methods to re-use produced water and then safely recycle or dispose it.

In heavy oil, Halliburton keeps water management at the forefront

To meet the challenge of thermal enhanced oil recovery (EOR), Halliburton has developed a number of unique technologies that help minimize water costs and increase hydrocarbon production. Although the use of conformance processes may not always result in increased production, such processes can often improve an operator's profitability as a result of the following benefits:

  • Longer production well life
  • Reduced lifting costs
  • Reduced environmental concerns and costs
  • Minimized treatment and disposal of water
  • Reduced well maintenance costs

Controlling CO2 emissions is of critical importance

Heavy oil contains higher levels of CO2 than methane or gasoline. Therefore, carbon capture and sequestration is critical for environmental reasons. In Canada alone, Halliburton estimates that by 2015, technologies will have prevented the escape of 650 Tcf of CO2 per year, and that 3,600 Tcf of CO2 per year will be captured for sequestration and enhanced oil recovery (EOR).

With EOR, both environmental and operational interests are served simultaneously. Extracted CO2 is pumped back into the ground to lower the oil's viscosity and actually push it to the surface, thereby boosting production.
