QUARTZIN — SAND CONTROL
Sand production like water and gas production is one of the oldest problems in the oil field. It is usually associated with shallow formations as compaction tends to increase with depth. But in some areas, sand production may be encountered to a depth of 12,000ft or more. Sand production higher than 0.1% (volumetric) can usually be considered as excessive, the practical limit could be much higher or lower.
In order to properly optimize production and monitor sand controlled well, it is essential to evaluate the well performance, sand control effectiveness and durability of the treatment type installed in order to achieve the main aim of hydrocarbon production. Sand production erodes downhole and surface equipment, block well tubular, creates downhole cavities, and must be separated and disposed of on surface.
The principal methods of sand control that are available in oil industry are gravel pack (GP), Sand screen (SC), and sand control using chemicals (SCUN). The challenge is to complete wells to keep formation sand in place without excessive production restrictions.
A consolidated sand treatment system, Quartzin maintain above 90% permeability retention, while increasing the formation compressive strength value.
A consolidated core treated with 15% mud acid after the injection of Quartzin without any sand production, the core split into two parts; one part was soaked in crude oil and the second in mud acid for a period of 90 days, this did not affect the quality of consolidation.

Water production in oil and gas reservoirs is a serious problem. The excess water stream produced alongside hydrocarbons has environmental, technical and economic effects.
Polymer gels, relative permeability modifier (RPM), zonal-isolation, are the common methods to control water production, which is effective in treating reservoir with multi layers and water coning problems, leading to a considerable reduction in water and hydrocarbons flow, however, this methods will not be effective if there is cross flow exists between layers.
AQUASEAL will change the wettability of the water-cone zone bringing normal hydrocarbon production, uses emulsified Nanoparticles with a cross-linked surfactant and relative permeability modifier to provide isolation for the water-coning zone during acid stimulation, due to their high surface area with enhanced emulsion stability, controlled separation time, and stable at a temperature above 90°C and salinity above 200,000 ppm.
Seal-WOC is a water wetting agent to reduce water cut in the well by controlling bottom water mobility and height. The treatment will delay the water breakthrough time and reduce water cut in the production fluids.</p> <p>Seal-GOC is a gas shut-off treatment, a use of viscoelastic surfactants to control gas coning and reducing gas oil ratio.
