Geologist at Saudi Geophysical Consulting Office
  • Saudi Arabia - Khobar
  • My current job since March 2014

 Completed a Project on Hydrogeological Study for Sharaan Resorts, Royal Commission for Al Ula, Kingdom of Saudi Arabia
o Prefeasibility Study, geology, Aerial photo maps, topographic map and physical survey of the area and select a most feasible location for bore wells.
o Analyze (logging) of rock cutting sample, collection of drilling and geological data and preparation of penetration log, lithology, water chemistry log, drilling _uid parameter log, borehole design.
o During drilling monitoring of hydro-chemical data, i.e., electrical conductivity, pH, TDS, Salinity, Dissolved Oxygen, Temperature and water bearing formation and its strike etc.
o Monitoring of drilling fluid parameters
o Supervision of Casing (PVC, Steel) installation
o Well development of the borehole by compressed air (Jetting /air lift), Surging back washing educator pipe methods.
o Prepare hydro geological map (water quality and water level map).
o Carry out Pumping test in different aquifer system which consist Calibration Test, Step Drawdown Test, Constant Rate Test, Recovery Test
o Writing of well completion reports based on geological, hydrogeological, drilling and pumping test data.

 Completed a project on Geological and Geophysical study of sinkholes and cavities in the Kingdom of Saudi Arabia under Ministry of water and environment, Government of Saudi Arabia from January2019 to December 2020.
• Collected data for sinkholes and cavities from old literature and reports done on the subject.
• Study of Geology, satellite imagery, aerial photos and physical surveys to locate various sites of sinkholes and cavities.
• Supervise percussion and rotary bore hole drilling to acquire subsurface geological data, identification of different geological layers and preparation of well site lithological logs.
• Correlation of bore-hole logs with Geophysical data (ERT and GPR) to locate the underground cavities.
• Prepared all GIS related maps for the project, surface geological maps, location maps, topographic maps, street maps, drainage maps etc.
• Prepared subsurface geological maps, 2D cross sections and 3D Geological model.
• Coordinated client and other officials related to the project.

 Worked as Assistant Geologist/Sedimentologist at Saudi Aramco from March 2014 to December 2018(as supplementary manpower from Saudi Geophysical Consulting office, AL Khobar, Saudi Arabia).
• Convert the scanned images of hand description into digital format description using WellCAD & Easycore software.
• Digitized data for core analysis include description of mineral composition, sedimentary structure, grain size, fossils and any other macro-features of the rock.
• Using digitized data in correlation and modeling of lithological properties with petrophysical properties for different wells.
• Ability of remapping of extracted data from the digitized core description sheets (e.g. Lithology, texture, structure etc.) by another software (e.g. Petrel, etc.).
• Extract any parameter from the digitized core description sheets for uploading into various software packages (e.g. Petrel, GEO logger etc.)
• Comparison of lithological properties with petrophysical properties and wireline log responses.

Project Assistant at Central Institute of Mining and Fuel Research, Dhanbad, India
  • India - Dhanbad
  • July 2012 to February 2014

• Identification, handling, storage and disposition of drill-hole cores and samples
• Field work - geological mapping, sampling, drilling, core logging
• Routine core analysis and generating lithological logs
