Geotechnical Drilling Works

ELITE is a premier provider of comprehensive geotechnical services, delivering end-to-end solutions from initial site sampling to advanced laboratory soil analysis for the oil and gas, petrochemical, and civil construction sectors. Leveraging a versatile fleet of specialized equipment, ELITE possesses the operational capability to execute conventional coring, wireline coring, windowless sampling, Standard Penetration Testing (SPT), and rotary open-hole drilling using both water and air flush methodologies.

To ensure maximum sample integrity and consolidation, ELITE utilizes advanced coring and sampling technologies tailored to diverse geological formations. For conventional coring, the team employs T6 116 and T6 H core barrels to extract protected $3\frac{1}{2}\text{''}$ and $2\frac{7}{8}\text{''}$ samples directly into protective internal plastic liners. Continuous coring and superior borehole stability are achieved using a heavy-duty PQ wireline system, which delivers $3\frac{1}{4}\text{''}$ core samples into a steel inner barrel while actively supporting the borehole wall during depth progression. For softer upper strata, windowless sampling is executed across three distinct barrel configurations ($75\text{ mm}$, $87\text{ mm}$, and $102\text{ mm}$ samples) utilizing interior plastic liners. Furthermore, SPT testing is conducted using standard split-spoon sample tubes driven by either a conventional trip hammer or a fully automated hydraulic rig system to guarantee precise data capture.

ELITE’s rotary open and cased-hole drilling capabilities accommodate varied structural demands through the deployment of premium Polycrystalline Diamond (PCD), Tricone, and Tricone Hard Formation drill bits. The company routinely drills cased holes utilizing robust HW and PW casings equipped with diamond-impregnated casing shoes. To provide a complete, self-contained field solution, ELITE operates proprietary grout mixers and pumps, allowing for seamless borehole installation, completion, and environmentally secure sealing.

Project mobilization across challenging terrains is supported by a highly adaptable drilling fleet. The compact Comacchio 305 is a rubber-track-mounted, diesel-hydraulic rig optimized for limited-access locations and sensitive surfaces like concrete or tarmac, with the added capability to drill shallow water wells up to $8\text{''}$ in diameter. For extreme topography, the bespoke P60 Slope Climber operates alongside its dedicated service vehicle, "The Mule." Equipped with robust steel tracks, a pivoting work platform, and integrated heavy-duty winches and anchoring systems, the P60 safely and efficiently executes shallow boreholes on steep inclines that remain inaccessible to conventional drilling assets.

Complementing its field operations, ELITE offers an extensive suite of laboratory soil testing services to deliver actionable engineering data for foundation and structural design. Analytical capabilities include moisture content determination, sieve analysis, Atterberg limits, consistency limit indices, Proctor compaction tests, direct shear testing, and dynamic California Bearing Ratio (CBR) testing, ensuring complete geotechnical compliance and precise design parameter verification for every project.
