Job Purpose: Reviews and evaluates geophysical/geological data in order to enhance understanding of geological structures with known hydrocarbon reserves and determine new hydrocarbon prospects (i.e. potential reservoirs). Includes preparing and analyzing time, velocity and depth maps based on accumulated data. (Studies cover all the Company’s concessional area). Principal Accountabilities: Analyses new data obtained from up-to-date seismic surveys utilizing the latest techniques in order to understand the subsurface structures with known hydrocarbon reserves. Includes updating parameters such s size, depth, closure of structure etc.. Studies new data to determine the existence of any new prospects. Generates time (ISOCHRON) maps by taking time readings at specified geological formations and contouring equal values. Obtains velocity data for various readings from existing wells in specified formation, establishes velocity maps (ISO velocity) accordingly and uses above information to calculate and develops depth maps. Prepares and updates ‘SHOT-POINT’ location maps based on co-ordination of every seismic shot taken during surveys. Identifies potential areas for drilling exploration or delineation (data gathering) well, co-ordinates with geologists and prepares the geophysical proposals for exploration and/or delineation well, accordingly. Oversees the processing of geophysical data, as required. Includes visiting external processing centre’s, selecting processing parameters and sequences to be applied in assessing seismic sections. Follows-up with processing centre to ensure the timely receipt of results. Checks and accepts data submitted by contractors utilizing specialized processing techniques. Supervises the recording and processing of well velocity surveys conducted in the exploration and/or delineation wells. Accompanies survey vessel during seismic operation, as required. Includes ensuring all terms, conditions and survey specifications are adhered to by contractor. Checks raw data collected on site to ensure accuracy and quality of data. Works in line with HSE policy, rules and regulations. Performs other related duties as assigned by Supervisor such; Carrying out Company studies to determine justifications for any deviations/anomalies in drilling results, liaising with other companys and/or regional oil companies for the mutual exchange of geophysical data, as requested. Communications & Organizational Relationships: Frequent contacts with Geologists and occasionally with Senior Engineers in the Division and with Surveyors/Draughts men in engineering Division for co-ordination of work. Occasional contacts with contractors and service companies, as directed for overseeing operations. Reports to Senior Exploration Geologist. Determines work method according to established practices and professional geophysical standards. Refers major technical problems and anomalies to Supervisor. Works accomplishments are subject to review by Supervisor.
