turnkey EPC for surface facilities and reconditioning of well 206, delivered by Entrepose Contracting
The first underground LPG storage facility in a salt cavern in Mexico and Latin America, Shalapa, addresses the growth of a significant national market that is heavily dependent on LPG for domestic use. The facility strengthens the security of supply for a system previously based on limited-capacity aboveground terminals, which are vulnerable to disruptions in production, imports, and logistics.
Located at the heart of the supply network for the south and centre of the country, the site relies on salt cavern 206 in the Tuzandépetl dome, operated by ASSE with Geostock support. Entrepose Contracting designed and built the surface facilities—process, utilities, pumping, and interconnections—under an integrated Entrepose/Geostock offer, combining civil works, surface process, and underground storage expertise within a highly demanding HSE context.
National strategic challenge: development of a large-capacity salt cavern (2.5 million barrels) and its surface facilities to secure LPG supply for southern and central Mexico.
Underground–surface integration: integrated EPC offer controlling interfaces, constructability, and project risks.
Site water management: hydrological studies, retention basins, drainage networks, and targeted diagnostics to limit leakage risks and protect soils and water resources.
Complex surface facilities: turnkey delivery of LPG pumping, metering, and treatment units (including dehydration), plus utilities and interconnections for high flow rates between the cavern, CYDSA/ASSE facilities, and Pemex-operated flows.
High HSE requirements: deployment of the Group QSE management system and a “zero accidents” culture, focusing on major risk prevention, operational control, and stakeholder coordination on an operating site.
Changing industrial context: contribution to the modernisation of LPG logistics amid Mexican market liberalisation, providing Pemex with a reference underground storage asset—safer and more competitive than aboveground solutions for large volumes.
