Schlumberger offers an extensive range of cleaning compounds to ensure asset operational excellence. Cleaning techniques that can be employed include filling and soaking, circulation, cascading, online, use of foam, and use of vapor phase.
Solvent-based products should be used when the deposits are mainly organic and particularly when temperature cannot be increased.
The range includes aromatics, white-spirit-based compounds, low-aromatic naphthas, and kerosene- and diesel-based products. Cleaning compounds can also be designed to produce either a stable or self-separating (quick break) emulsion on flushing with water.
Aqueous cleaning compounds are easier to handle and in many cases provide a more cost-effective treatment than solvent-based products. They can also be made more environmentally acceptable but are not necessarily as efficient.
Aqueous products can be used in almost all cases and especially for solid-particle deposits, but they are not particularly suitable for removal of hard, mechanically-resistant organic deposits when the temperature cannot be raised to soften the deposits. Small amounts of organic solvents can be included in aqueous products to improve solvent properties.
