15. A systematic approach to the interpretation of conductivity anomalies recorded with the Geonics EM34-3 electromagnetic instrument across intrusive dolerite dykes and sills in the Karoo Supergroup

Ms Dakalo Makhokha (Institute of Groundwater Studies-IGS:UFS)

Oral and Poster Presentation

Groundwater exploration has become increasingly dependent on the use of geophysical techniques to gain insight into the subsurface conditions to minimise the risk of drilling unsuccessful production boreholes. Dolerite dykes and sills are often targeted during groundwater exploration programmes in Karoo rocks. Due to the high pressures and temperatures that reigned during the emplacement of...

12. Development of a D.C. Resistivity Modelling Laboratory for the Simulation of Wenner, Schlumberger and Dipole-dipole Configurations

Mr Vincent Mabunda (Tshwane University of Technology)

02/10/2014, 16:45

Oral and Poster Presentation

D.C. resistivity is an active geophysical method that employs the measurement of electrical potential associated with subsurface current flow, generated by a D.C. source. The purpose of any D.C. resistivity survey is to determine the vertical and lateral subsurface resistivity distribution through measurements on the ground surface. D.C. resistivity is one of the principal electrical...

40. Assessments of the Effects of Clay Diagenesis on Some Petrophysical Properties of Lower Cretaceous Sandstones, Block 3A, Offshore Orange Basin, South Africa

Mr Chris Samakinde (University of the Western Cape)

02/10/2014, 17:00

Oral and Poster Presentation

Clay minerals diagenesis phenomenon and their effects on some petrophysical properties of lower cretaceous silliciclastic sandstones, offshore Orange basin have been established. Previous studies on Orange basin revealed that chlorite and quartz cements have significantly compromised the reservoir quality in this basin but it is expected that the reservoirs shows...
