Test Results for Frac Sand Suitability at Santa Lucia
The ISO 13503-2 standard stipulates the characteristics (roundness, sphericity, crush resistance and chemical resistance) required for a sand to be suitable as a 'proppant' for use in oil and gas extraction from shale by hydraulic fracturing. Test results show that the sands on the Santa Lucia property meet or exceed these ISO specifications for frac sands.
Fraction: initial sampling shows that the 40/70 fraction (grains are between 0.2 millimetre ('mm') and 0.4mm in diameter) of the sand meets ISO requirements for fracking purposes. Approximately 40% of the bulk sand is in the 40/70 fraction - a grain size commonly used for the extraction of oil, as opposed to gas, from hydrocarbon-bearing shale layers.
Sphericity and roundness: tests show that the sand from the Santa Lucia property has average sphericity and roundness values of 0.7, which exceed ISO specifications that require average minimum roundness and sphericity values of 0.6.
Turbidity: the target sand meets the ISO specification for turbidity with a value of 8FTU (Formazin Turbidity Units), which is well below the maximum allowable value of 250FTU. Turbidity is the cloudiness of a fluid caused by minute suspended particles.
Crush test: a measure of the strength of the sand grains, and therefore their ability to withstand the pressure that the overlying rock would exert on the sand-filled fractures in the shale. This resistance is measured by the percentage of fine quartz shards and fragments that split off the quartz grains during pressure tests.
The maximum proportion of quartz shards permissible for the 40/70 size fraction under ISO standards is 8% after the sample has been subjected to a pressure of 5,000 pounds per square inch ('5Kpsi'). The composite sample from the Santa Lucia property exceeds those requirements with 7.4% quartz shards measured after the crush test on the 40/70 size fraction.
K-Value: test work shows the sands at Santa Lucia exceed this measure of the estimated pressure in Kpsi that would result in 10% shard and fragment development.
Nature of the Santa Lucia Target
The unconsolidated sand in the Santa Lucia concession block lies at surface in sparse vegetation over an area of approximately 260 Ha and is estimated to be at least seven metres ('m') thick. (The bulk density of the sand is 1.47t/m3).
Since the ground water table lies approximately 2m below surface, the sand is likely to be amenable to hydromining in which an initial excavation is made and allowed to fill with groundwater. Hoses are used to slough sand from the edge into the pool from where it is dredged, wet screened and readied for packaging and shipment.
The excavation advances across the mining area with material excavated from the leading edge of the pond being screened to extract the component of the sand that has desirable fracking characteristics, and the residual material being replaced at the trailing edge of the pool where it is subsequently re-vegetated. This mining method is not only cost effective and efficient, but it minimizes the generation of dust so that the frac sand can be mined, processed and handled under the highest health and safety conditions.
