KEY PERSONNEL

HANIF BIN MOHAMAD

Hanif bin Mohamad is a bachelor’s degree graduate in Petroleum Geoscience from Universiti Teknologi Petronas, Perak. He started his career in GEOMAG GEOLOGICAL SDN BHD in 2016 as engineering geologist. His involvement in GEOMAG GEOLOGICAL SDN BHD has given him a wide range of knowledge and skills in technical and project management. Throughout his involvement in the industry, he has been involved in several site investigation works such as geophysics surveys, terrain mapping, geomorphological mapping and borehole supervision.

He has extensive skills and knowledge in the field of geophysics, and appointed as Head of Geophysics Unit in 2020. He also actively participates in training course, event, conference, and technical talk held by other organization. He is one of the members in Geological Society of Malaysia. He registered with the Board of Geologist (BoG) as Graduate Geologist since 2017.

Among the projects he was involved in were the iron ore exploration in Gurun, Kedah, landslide study in Serendah, groundwater exploration in Lebir Kelantan, geohazard mapping in Cameron Highland and soil investigation in Mergong Kedah.

He is one of the personnel of GEOMAG GEOLOGICAL SDN BHD with high spirit and determination. The positive attitude and mindset he possesses has been one of the main factors that enable him to move forward.

EXPERTISE & SERVICES PROVIDED

GEOPHYSICS SURVEY

We are providing three services:

Resistivity Survey
- Making use of subsurface resistivity properties to produce subsurface profile for construction work, developing area and planning site.
- The tool used is the Terrameter LS Lund from Sweden.

Seismic Survey
- Extracting information of subsurface within certain area by using seismic waves.
- This method can give information about the hardness of rock layer based on velocity of the wave travel throughout the layers.
- The tool used is the ABEM Terraloc MK6 24-Channel.

Downhole Geologging
- Use to determine the physical properties and rock surrounding the borehole annulus.
- From this geophysical logging, physical properties such as density, porosity, thickness, orientation, and lithological identification of soil and rock surrounding borehole annulus may be determined.
- The equipment used is 3 Arm caliper probe, Electric Log Probe, 45mm Impeller Flowmeter Probe, Temperature Conductor Probe, Mini Winch and Micro logger from Geo Robertson, United Kingdom.
