• EPC services for Kunnar LPG Recovery Project - operating since September 2000.
• EPC services for Bobi LPG Recovery Project - engineering work completed and construction to start shortly.
• Basic detailed engineering of Gas Gathering Network and processing facilities of Tando Alam Facility.
• Construction supervision services for Pirkoh Gas Compression Project - in commercial operation.
• Consultancy services including tender document bid evaluation and design review for dehydration plants at Pirkoh Field.
• Construction supervision for 300 MMSCFD Uch Gas Processing Facility including 11 MW power station and other utilities designed by ENAR and a very large (60 million gallons) water storage and delivery system.
• Construction supervision services Qadirpur Gas Processing Complex (Phase - I)

ENAR has recently completed the Qadirpur Capacity Enhancement Project. The work undertaken included, carrying out process design, detailed engineering, project/ construction management, procurement support (600 MMSCFD Mega Membrane Facility). Prior to this assignment ENAR carried out an in-depth evaluation of UOP's Proposal for enhancement of Qadirpur Gas Processing Capacity. Apart from this project ENAR has also prepared FEED Document for MOL's Gurguri Gas Plant, PEL's Badar & Kandra Gas Processing Facilities and PPL's Adhi LPG/NGP Plant II including detailed engineering of package equipment.

ENAR has also carried out design engineering work of following Gas Processing Projects:

• Basic and detailed design of Tangri Mazari: Amine Plant Upgrade Facility - BP Pakistan Limited (Formerly UTP)
• FEED Document for Mazarani Gas Processing Facility - Pakistan Petroleum Limited (PPL).
• Engineering Verification of Miano - Kadanwari Upgrade Project for OMV Pakistan Limited
