TUNISIA
Serinus Tunisia maintained a strong HSE track record through 2022, with a zero-frequency rate (per one million
man hours worked) for Total Recordable Injuries across all sites (2021 – zero for Serinus Tunisia employees).
There were no environmental incidents at Sabria and five minor incidents at Chouech Es Saida which were
addressed and repaired. Serinus Tunisia has maintained full compliance with all of its regulatory and environmental
obligations.
Environmental monitoring has been undertaken across all of our Tunisian fields since 2014 in compliance with legal
requirements and the Company’s responsibilities to the local environment. The annual environmental report for
2022 was submitted to the Agence Nationale de Protection de l’Environnement (“ANPE”) in January 2023.
During 2022, the annual environmental monitoring was undertaken by Le Centre Mediterraneen d’Analyses (“CMA”)
at the Sabria and Chouech Es Saida fields, assessing: air emissions from stacks at both fields; air quality monitoring;
groundwater monitoring; produced water; fresh water; soil sampling and noise pollution. The environmental
monitoring programme for remote locations is reviewed by local management and implemented at all sites.
Stack air emission analysis and air quality monitoring was conducted at Sabria and Oum Chiah in October 2022.
Analysis of the results demonstrated that the Company was in compliance with approved thresholds of groundwater
and soil contaminants and required solid waste management. The Company’s own review of air emissions showed
compliance in all areas, in accordance with the air quality limits set by Decree No. 2018-447 of 18 May 2018 and
Decree No.2010-2519 of 28 September 2010, except for carbon monoxide (“CO”) emissions from older fixed
equipment. The Company has investigated mitigation measures and a short and medium-term action plan with an
enhanced preventative maintenance programme has been implemented to address this, including the refurbishment
and overhaul of affected equipment. Ground water monitoring is conducted on a yearly basis from existing water
wells drilled at Sabria. No evidence of pollution has been reported. Five piezometer wells were drilled at Sabria to
monitor the ground water table in 2014 which continue to be monitored.
The water disposal project manages produced water production at Sabria. This formation water has high salinity
(360 grams/litre) with traces of heavy metals. Until 2015, disposal at Sabria was conducted by discharge into lined
surface pits for natural evaporation of fluids. The low efficiency of natural evaporation together with the ongoing
need to construct additional lined pits led to the introduction of automated fracturing evaporator technology in 2015
and which has enabled the acceleration of evaporation of produced water through an automated and a more efficient
process. At Sabria, 49,129m
3
of produced water was disposed of in 2022 (2021 – 45,598m
3
) and at Chouech Es
Saida 225,283m
3
of produced water was evaporated from lined surface pits in 2022 (2021 – 193,400m
3
). The
Company is investigating alternative environmentally-responsible produced water disposal solutions.
A review of environmental management at the Sabria fields was conducted by First North African Consultancy for
the Environment (“FNAC” www.fnac-environment.com), an engineering consultancy, in September 2020. This was
designed to review compliance at Sabria with Tunisian environmental regulations and analyse underground water
and soil pollution in proximity to the water disposal project. The scope of this work included: the recovery, analysis
and assessment of environmental and technical documents and reports related to the evaporation ponds; the
analysis of all previous waste pit treatment operations and related reports; analysis of existing red register
(hazardous waste) and blue register (domestic waste); coring and sampling investigations of the potential impacted
areas (soil and underground water) within the Sabria field; water sampling and laboratory analysis from existing
piezometers and production water discharge; and the performance of an environmental monitoring program of the
potential impacted areas within Sabria field. The program was conducted in conjunction with representatives of
ANPE and the environmental reports were submitted to ANPE. Results from the assessment showed below
threshold levels of potential pollutants set under Tunisian regulations and equivalency with both groundwater and
soil control samples. These demonstrated the efficacy of the water disposal project and the process of produced
water storage in evaporation pits, with no evidence of leakage or overflow from the pits into the soil or groundwater.
Subsequent to this review, recommendations from the report have been, and continue to be, implemented. The
Company began air emissions monitoring at Sabria and Chouech in August 2015 and continues to do so.
Waste management procedures have been implemented in all locations in Tunisia and monitor a comprehensive
range of waste products including industrial waste (dry cell batteries, lead acid batteries, empty gas cylinders, oil
filters, used oil, contaminated waste, used fluorescent lighting), resource waste (diesel consumption), hazardous
waste (sewage, medical waste), domestic waste (food waste, plastic bottles, cooking oil, paper) and office waste
(plastic bottles, paper, printer cartridges, batteries). For example, 822 kg of paper and plastic bottles were recycled
in the Tunis office in 2021, which increased to 1,164 kg of paper and plastic bottles being recycled in 2022, as a
result of training and greater awareness of wastage. Electricity consumption at the Tunis office in 2022 returned to
more equivalent pre-COVID-19 levels of 93,920 kWh, as personnel returned to work in the office. At Sabria
electricity consumption decreased 5% to 679,902 kWh (2021 – 717,836 kWh). Chouech is not connected to the
electricity grid and power at Chouech is provided by on site gas generators. Fresh water consumption in 2022 at
Sabria was 16,290m
3
(2021 - 14,949m
3
) and at Chouech, 41,440m
3
(2021 - 65,558 m
3
). Diesel consumption across
all operational locations was 153m
3
a 4% decrease over 2021 (160 m
3
) but remains a significant reduction from
2019 (305 m
3
) reinforced by a combination of greater awareness of wastage, training, optimisation and more
efficient transport management.
