Based on our many years of experience and our own organizational and technical capabilities,
Iskander GRK LLP offers a wide range of drilling and related works :
DRILLING OPERATIONS
- Core drilling BQ, NQ, HQ, PQ;
- Geotechnical drilling with core orientation;
- RC drilling (reverse circulation);
- Pneumatic impact drilling;
Counterflush core drilling;
- Geological exploration (core boring, coring)
- Geological exploration (non-core drilling)
- Geotechnical (with core orientation)
- Process (increased diameter with heavy sampling)
- Engineering & geological (study of soil properties)
- Hydrogeological (survey of water inflows and partial water supply)
ACCORDING TO THE PURPOSE OF THE WELLS:
ACCORDING TO THE DRILLING CONDITIONS:
- Complete and high-quality drilling process in any region in an offline mode;
- Able to work stably in various climatic conditions, regardless of the season;
- Experience in hard-to-reach and remote areas;
- Drilling in difficult mining and geological conditions where the successful completion of the
operation requires using qualified technical and technological methods: - Karst cavities and intersection of previously passed underground mine openings;
- Drilling wells in unstable rocks (sands, quicksands, flooded horizons),
- Highly fractured rocks with complete absorption of drilling fluid,
- Soluble rocks such as rock salt,
- Rocks with very high hardness
- Ensuring core recovery in core wells of at least 95%, regardless of drilling conditions, if
necessary, use of special technical equipment and unique drilling modes - Strict control over the direction of the well route, keeping the deviation from the given direction within 3º-5º in inclination angle and 5º-7º in azimuth
- Reliable conservation or abandonment of wells in accordance with environmental requirements
- Complete reclamation of well drilling sites with restoration of temporarily damaged soil and vegetation cover
