BAKU, Azerbaijan, June 2
By Leman Zeynalova – Trend:
BP generated 40 percent less total hazardous waste in Azerbaijan in 2019 than in the previous year, Trend reports citing BP in Azerbaijan Sustainability Report 2019.
“The hazardous waste streams generated in a less quantity were water oily and those generated from our drilling activities. The reduction was mainly due to the restoration of the cutting reinjection wells on the West Chirag platform in 2019 and the further reinjection of a major part of hazardous waste into those wells from this offshore installation,” reads the report.
BP said that another reason for the reduction in total hazardous waste were fewer drilling activities in 2019 compared to the previous year.
“Almost a half – 43 percent of the total hazardous waste was sent for reuse and recycling. The largest recycled streams were cement and oils,” said the company.
BP generated 37 percent less nonhazardous waste in 2019 than in 2018.
“This was mainly due to less construction debris produced throughout the year compared to 2018 when the Shah Deniz 2 site expansion project at the Sangachal terminal was executed. We achieved 60 percent reuse and recycling rate of non-hazardous waste in 2019, which is slightly less than in 2018. The recycled non-hazardous waste streams mainly included metal scraps, plastics, paper, cardboard and wood,” reads the report.
In 2019, BP continued its drilling activity in the Caspian Sea, generating about 57,500 tonnes of drilling muds and cuttings - about 15 percent more than in 2018.
“We also continued to reinject drill cuttings to subsurface with the total volume 15 percent less than in the previous year. About 48 percent of all drilling fluids shipped to the shore was recovered in the form of base oil and water, compared to 36 percent in 2018. The permitted discharges of muds, including other drilling fluids and cuttings, to the sea as a result of the routine drilling activities in 2019 were equal to 25,663 tonnes. These were mainly discharged from the Chirag platform, the Istiglal and Maersk Explorer mobile drilling units. This volume also included mud and cuttings discharges associated with the pilot hole drilling as part of the Azeri-Central East (ACE) project,” reads the report.
