NAGECO North African Geophysical Exploration Company (NAGECO) was formed as a joint venture company between the National Oil Corporation (NOC) of Libya and Western Geophysical of Canada on the 30th of June 1987. In 2009 NOC assumed full ownership of NAGECO Inc. Since it’s formation, NAGECO has continually operated at least two seismic field crews and provide a serves in the Libyan Oil Sector bought 2D &3D with a proven package of services at competitive prices using a combination of leading edge equipment , personnel trained to the highest industry standards and a rigorous Health, Safety and Environment (HSE) programme, NAGECO, with its many years of experience, offers complete data acquisition services as well as data processing. NAGECO’ s core field equipment includes Sercel Nomad 65 vibrators as well as anew Sercel 428 recording system. Our modern equipment lets NAGECO offer reliable, proven solutions and , linked with our many years of experience , ensuring the Murzuk Sand Sea absolute minimum of downtime . NAGECO NAGECO currently operates two fully equipped 3D crews capable of working in all types of terrain . Using Sercel’s modern telemetric recording systems permits NAGECO to address the most demanding of parameters and to meet the ever increasing demand for a higher number of channels . Over the years NAGECO has carried out many 3D and 2D surveys for a variety of clients , including waha , Total , Agoco , Zueitina , Wintershall ,Sirte ,Agip Gas , Veba , Ina- Naftaplin OXY , RWE and Alepco . Health ,safety and Environmental concerns are fully addressed and complied with through NAGECO’s rig orous HSE policy which covers all areas of the company. All crews are equipped with ambulances and its HSE department constantly monitors compliance of every department to the HSE standards that clients (and NAGECO) requires. HSE NAGECO NAGECO communications network between the field crews and town is maintained using satellite internet and satellite telephones as well as cell phones , where coverage allows . All field vehicles are fitted with modern Motorola FM radios . Garmins are also available . Surveying is carried out using modern leica 12oo series GPS field equipment, our fully trained and equipped survey teams carry out the complete survey at field level ,using the most modern processing , mapping and imaging software. From the establishment of control networks through to the final mapping and survey reporting , all the surveying is done on site in the field . Data copying and storage are additional services that NAGECO offers .Data storage solutions, such as, Cartridge, CDR and Exabyte are the preferred media of most clients NAGECO has Data Processing Centre, enabling NAGECO to offer clients a complete solution from programme design to fully processed data. North African Geophysical has, over the last 30 years, gained a prominent position as one of the leading seismic contractors in Libya. We look forward to the next years.

Organic matter type and richness were based on well control. Kinetic modeling was used to calculate hydrocarbons generated and expelled from the source-kitchens. Discovered original oil (or oil equivalent) in-place (OOIP/OOEIP) reserves were compiled. The undiscovered amount defines the remaining potential.
