Tackling methane in our US onshore gas business

We are one of the largest natural gas producers in the US, and have been taking action to reduce methane emissions for many years

Our actions – from 1999 to 2018

1999 – methane graphic

1999

 

  • Used enhanced automation to reduce methane emissions during a process in which we periodically remove liquids that have accumulated in a well.
2000 – methane graphic

2000

 

  • Pioneered a technique known as green completions that captures gas that would otherwise be flared or vented as wells are completed.
  • Began programme to replace high-bleed controllers with ones that emit less methane.

2001

 

  • Began tracking sustainable greenhouse gas reduction activities in our operations.

2005

 

  • Started using solar pumps instead of gas pneumatic pumps for chemical injection.

2007

 

  • Began using solar-powered generators in place of thermal electric ones to power equipment that helps prevent corrosion.

2009

 

  • Introduced a carbon price in our investment decisions for certain large projects.

2015

 

  • Completed our first multilateral well. Drilling multiple horizontal wells from one vertical wellbore requires less equipment than drilling individual wells from multiple well pads. This reduces the potential for leaks from equipment.

2017

 

  • Trialled the use of drones and truck-mounted laser sensors to detect and quantify methane leaks.
2018 – methane graphic

2018

 

  • Began using solar pumps instead of gas pneumatic pumps to circulate heated fluid that helps protect pipes from freezing.
  • Neared completion of the programme we started in 2000 to replace around 10,000 high-bleed controllers.
