Reducing Environmental Impacts on Water and Health through Well Lining and Cementing in the Algerian Desert

Abstract

The processes of casing installation and well cementing are fundamental techniques for minimizing the environmental impacts of oil and gas operations on water resources and public health, particularly within the sensitive desert ecosystems of southern Algeria. These operations aim to prevent hydrocarbon leakage into groundwater layers, thereby reducing water contamination risks and preserving the health of local communities. The system relies on advanced technologies, including high-quality cement and environmentally friendly additives to enhance zonal isolation and minimize fluid permeability. Moreover, early leak detection systems employing remote sensing and spectral analysis techniques are used to monitor abnormal changes in geological formations. In this context, Hydraulic Liner Hanger (HLH) technology offers a more advanced and reliable solution compared to conventional mechanical systems, improving zonal isolation while significantly reducing environmental risks and operational emissions. Its successful implementation in the OGME-1 well at the Hassi Messaoud oilfield — the largest petroleum field in Algeria — demonstrated its operational efficiency and environmental advantages. The tools deployed in these operations include rotary drilling units, high-pressure cement pumping systems, and geological formation analysis probes to ensure tight sealing and prevent leaks. Field studies conducted across several regions of the Algerian desert highlighted the importance of adopting Resource Management and Valorization strategies to enhance the efficiency of water and energy use in the petroleum sector, thus supporting sustainable development initiatives.
