INTRODUCTION TO SIWES
Purpose: Equip students with industrial skills and
experience.
History: Established by the Industrial Training
Fund (ITF) in 1973.
Objective: Bridge the gap between theory and
practical application
ORGANIZATION OVERVIEW
Name: Eldee Group of water drilling &
Geophysical Survey.
Location: Oraifite, Anambra State
Specialty: Borehole drilling, Groundwater
surveys, Environmental assessments.
Established: 2004
BOREHOLE DRILLING OPERATIONS
The processes of pre-drilling operation include:
Preliminary oral investigation: To get
information about the geology of the area
Inspection of the site: To study relief and
vegetation
Geophysical survey: To study the character of the
formation.
Site preparation: To mobilize equipment, clearing
and construction of pits and channel
GEOPHYSICAL SURVEY TECHNIQUES
Method Used: Electrical resistivity method
Equipment: Terrameter, electrodes, and cable
reels.
Purpose: Map subsurface geology and locate
aquifers
BOREHOLE DRILLING TECHNIQUES
 Mud rotary drilling
 Fluid is pumped down the drill pipe and out of jets in the drill bit.
 The fluid carries cuttings to the surface, where it is recycled.
 Suitable for unconsolidated rock formations.
 Air Rotary Drilling:
 Drill bit rapidly rotates to cut through rock formations.
 Air is used as the circulating medium to cool the drill bit and carry cuttings
to the surface.
 Best for consolidated rock formations.
Steps:
Geophysical survey → Drilling → Casing →
Gravel packing → Pump testing.
EQUIPMENT USED IN BOREHOLE DRILLING &
BOREHOLE STRUCTURE COMPONENTS
 Motorized Drilling Rig
 Drilling Bits (Clay Cutter,
Diamond Bit, Hammer)
 Drilling Rods and Casing
Pipes
 Compressors and Pumps
 Gravel Packing and
Grouting Tools
Drilling Depth: Varies based
on geological conditions.
Borehole Diameter: Typically,
8 inches.
Casing Pipes: Prevents wall
collapse and ensures water
quality.
Gravel Packing: Stabilizes
formation and prevents fines
from entering.
CHALLENGES IN SIWES AND BOREHOLE
DRILLING
Limited supervision due to inadequate funding.
Employers’ limited time for student training.
Expensive equipment and tools.
Difficulty in deepening existing boreholes
BENEFITS FROM SIWES
Practical experience with electrical resistivity for
groundwater exploration.
Borehole drilling supervision.
Effective teamwork and client interaction.
RECOMMENDATIONS
Increase funding for SIWES.
Mandate licensed contractors for borehole drilling.
Regular monitoring of groundwater resources
CONCLUSION
•SIWES provides invaluable practical experience.
•Emphasized the importance of bridging academic
and industrial gaps.
