ABOUT ME
From field evidence to integrated geological interpretation
My work begins with direct geological evidence - outcrops, stratigraphic relationships, structural measurements, drillhole and core records, well logs, petrographic observations and fossil assemblages - and develops these data into maps, correlations, cross-sections and three-dimensional models.
Field geology and mapping
Systematic mapping in Karangkancana integrates geomorphology, stratigraphy, Halang sandstone-claystone interbeds, fault-related deformation, Lebakwangi limestone-karst features, Kumbang volcaniclastic rocks, petrography, micropalaeontology and geological cross-sections.
Mining and coal geology
Thesis and PT Bukit Asam internship work connect seam observations, roof-floor-parting and interburden descriptions, core data, Gamma Ray-Density logs, coal-quality relationships, electrofacies, correlations and MineScape geological outputs.
Oil, gas and subsurface
Petrel workflows cover multiwell correlation, seismic display, horizon picking, fault-stick review, fault-surface construction and structural-framework inspection as project-based technical practice.
Geothermal and energy
Technical visits to Pertamina Geothermal Energy Area Ulubelu and Pertamina Hulu Rokan Zone 4 provide industry exposure while transferable subsurface, structural and modelling skills support broader energy-geoscience development.
Structural and geotechnical
Field measurements, fault-zone and fracture documentation, stereographic analysis, Dips and Slide2 workflows connect structural interpretation with discontinuity and slope-stability assessment.
GIS and digital modelling
ArcGIS Pro, MineScape, Petrel, Surpac, Vulcan and Micromine are organised by the geological task performed: data preparation, interpretation, surface or domain construction, validation and output review.
Research and scientific communication
The portfolio includes an accepted electrofacies manuscript, thesis and internship reports, mapping synthesis, scientific figures, appendices, presentations and source-linked technical explanations.
Leadership and project coordination
As Organising Committee Chair for Pertamina technical-visit programmes, I coordinated the committee, participants, schedule, host communication and documentation. This is presented as leadership and industry engagement, not employment experience.
