Drilling technologies

In 2022, KPO continued building on the strong foundation laid in the past years, working on minimising the impact of drilling and well services operations on the environment. As previously, we continued our journey towards zero emission and applied measures listed below to reduce greenhouse gas (GHG) emissions, and consumption of water and resources:

  • Continued initiatives such as using wireline instead of coiled tubing for post stimulation.
  • High-efficient environmentally friendly burners to eliminate where possible / reduce the need for flaring and the need for disposal of contaminated fluids.
  • Restarting our drilling campaign, delivering wells that will allow increased oil production offsetting existing high gas producing (GOR) wells.
  • High Rate Well Test setup with High Pressure Separators combined with multiphase high rate flow pumps (High Gas Volume Fraction Pumps – HGVF) to enable ‘zero’ flaring well test / clean-up activity on new wells.
  • Use of the light workover rigs (ZJ-20) instead of the 3000HP heavy rigs to complete intervention and workovers on wells 628 and 201. This ensured lower emissions and lower environmental footprint to achieve our objectives.
  • Our in-field Eco Centre or waste management centre enables recovery of base oil from contaminated drilling fluids and drilled cuttings for re-use in well intervention activities.

The KPO Well Operations team continuously works on developing internal procedures, workflows, technology improvements and innovations aimed at improving efficiency and well operations’ performance. The following was achieved throughout 2022:

  • Development and implementation of a “Business Improvement Plan” to drive efficiency of well delivery with strong focus on digitalisation and performance improvement.
  • Step-up in well integrity monitoring and well integrity status – preventing and reducing the possibility of well integrity related environmental emissions.
  • Utilisation of new technologies like local expander (ability to repair the well locally, thereby avoiding the need to re-drill) and tracer technology – driving efficient production.
