Geophysical investigation for groundwater potential of Lembangan Sungai Similajau, Bintulu Malaysia

Geophysical investigation for groundwater potential of Lembangan Sungai Similajau Area, Bintulu, Malaysia has been carried out with the aim of delineating suitable site for groundwater development and estimating the depth to aquifer. Electrical resistivity profiling techniques using Schlumberger configuration were used to delineate the subsurface geology of the study area. For the multi-electrode resistivity survey, the Schlumberger array was conducted by employing twenty nine (29) resistivity survey lines, where data were collected by using the ABEM LS II electrode selector system, and processed by using RES2DINV software. The images were presented in the form of two-dimensional (2D) resistivity profiles providing a clear view of the distribution. Lithological, the study area is consisting of Setap Shale Formation and Nyalau Formation. The integration of geological and geophysical surveys has provided a more accurate interpretation on the groundwater investigation of the study area, in particular for locating drilling sites. Groundwater resources are more potentially accumulated in these areas where potential groundwater zones in the study area can be classified as deep hard rocks aquifers. Resistivity survey Line is located in a wide open field with the maximum penetration depth 150m. The suggestion drilling locations are mark with the black line in the profile.
