Shot Hole Drilling

Shot Hole Drilling (SHD) is a key process in land-based seismic surveys, designed to create energy sources for imaging subsurface geological structures. This technique is widely used in oil & gas, coal, lignite, and mineral exploration projects.



• Survey & Planning – Selection of drilling points based on seismic survey design, terrain conditions, and environmental considerations.

• Drilling of Boreholes – Vertical boreholes are drilled, generally 15–40 meters deep and spaced 20–60 meters apart, depending on subsurface requirements.

• Loading of Explosives – Boreholes are safely charged with calibrated amounts of seismic explosives.

• Tamping & Sealing – Holes are backfilled with inert material (tamping) to ensure energy is directed downward.

• Controlled Detonation – Explosives are fired in a timed sequence to generate seismic waves.

• Seismic Data Acquisition – The waves are captured by geophones/hydrophones, processed, and interpreted for geological insights.

• Oil & Gas exploration (structural mapping, reservoir delineation)

• Coal and lignite block assessment

• Mineral prospecting and resource evaluation

• Engineering site investigations

• Groundwater studies in select terrains

• End-to-End SHD Services – from site preparation to drilling, charging, and post-survey restoration.

• Advanced Drilling Equipment – mechanical and manual rigs suited for diverse terrains, including hard rock, overburden, and loose soil.

• Trained & Certified Teams – skilled drillers, explosive handlers, and seismic technicians ensuring safety and compliance with regulatory standards.

• HSE Standards – strict adherence to Health, Safety & Environment protocols, minimizing environmental footprint and ensuring community safety.

• Operational Flexibility – capability to work across remote, forested, and challenging terrains in India and abroad.

• Reliable, high-quality seismic source generation

• Safe handling of explosives under DGMS & PESO guidelines

• Rapid mobilization and efficient project execution

• Proven track record in supporting major E & P and mining companies
