10 First Case Study Workshop ( Lecture ) 1- Geo X - Basic prospect resource and risk assessments - standard volumetric and risk input - different way of modeling volumes - aggregation - best practice, configuration and system tool - Basic play resource and risk assessment - play assessment - calibrating and framing prospect analysis 2- Resource assessment principles and resource classification. -four Levels - basin, petroleum system, play, prospect - basin methods of petroleum resource assessment - principles and procedures of play assessment - principles and procedures of prospect analysis - CCOP petroleum resource classification - geologic risk assessment First Case Study Workshop ( Discussion ) - Database Building - Parameters - Resource Estimation - Possible training and expert help 10

11 First Case Study Workshop ( recommendation ) Database - prepare data for economic analysis - Make inventory of digital data format and quality - CNPA should require companies to submit data Technical work to be done by CNPA - Define play and make play map - Play assessment ( Play/prospect analysis ) - Isopach thickness maps and porosity maps. - Find cost data for this area. - Geochemical modeling, petrophysical analysis, geology of the basin - seismic interpretation and petroleum engineering Workforce-Human resources: - More CNPA staff for the Case Study - External participants : Thailand, Malaysia, Vietnam etc. - Expert Support. First Case Study Workshop ( improvement ) Technical Lectures should not be too detailed More visual aids, less text in the presentations Lecturer should use actual data or true examples during software training Language barrier individual preparation recommended Forced grouping and forced presentation by individuals More geological outcrop to be visited; more geology-related field trips Administration More convenient bus transport on field trip CNPA to arrange guided shopping trips Provide time for shopping CNPA had problem with international communication (fax) Move location of next workshop Angkor Wat or Sihanoukville? Other member countries/participants will support by providing laptop computers 11
