Sentence examples for high calcite content from inspiring English sources

Treat formations with high calcite content.

The need of acid chelating blend, as the main acid, emanates from the relatively high calcite content (>6 %), and the high reservoir temperature (252 °F).

Rock analyses obtained from microscopic petrography, SEM, EDS and XRD emphasize the high calcite content of the rock and the variable composition and porosity of the stylolitic zones.

The well is depleted, has low-permeability (15 mD) clay-rich sandstone that is at high temperature (252 °F) with relatively high calcite content, and with a long production interval.

For the Dulang oil field, in actual practice, an organic clay acid was injected for removing problems of fines migration in a reservoir that has a high calcite content, with a moderate amount of feldspar and chlorite clay.

However, at this combination of high temperature, high calcite content, presence of moderate amount of feldspar and chlorite in addition to fines migration problem, a better main acid solution becomes the chelant-based acid recommended by the acidizing expert system.

HAP was found to be slightly more efficient on GS than GL, in terms of tensile strength, in spite of the higher calcite content of GL: this is probably to be ascribed to the different size and shape of micro-cracks that formed in the two stones after artificial weathering; indeed, HAP ability of sealing cracks substantially depends on the crack size and shape.

Quantitative statistics show that in reservoirs with high cement (calcite) content, reservoirs exhibit porosity loss from compaction of about 10% 20% %.

It was found that the lower the degree of saturation during calcite precipitation and the higher the calcite content in the samples, the higher the liquefaction resistance of the EICP-treated sand.

Formations with low clay content, at high temperatures and with significant calcite content are treated with acid chelating blends.

Organic clay acid would be useful for removing problems of fines migration at high reservoir temperature, provided that the calcite content is low.
