Case Study ONE-TROL Additive Saves 17.5 Hours of Rig Time in HPHT Logging Operation, Gulf of Thailand
Filtration control additive eliminates mud conditioning trips between logging runs.
High-temperature filtration-control additive
ECOTROL HT filtration-control additive can be used in all oil- or synthetic-based mud systems to provide HPHT fluid loss control up to 500 degF [260 degC]. This product readily disperses into a fluid system through standard mixing equipment, thus minimizing the potential for polymer 'fish-eyes.'
|Typical Physical Properties|
|Physical appearance||Granular solid|
|Solubility||Nonsoluble in water; soluble in polar and nonpolar solvents|
ECOTROL HT filtration-control additive is added at concentrations between 2 and 4 lbm/bbl [5.7 and 11.41 kg/m3] depending on the fluid-loss-control requirements and the bottomhole static temperature. In some cases, higher concentrations of ECOTROL HT additive will be required for an efficient filtration control.
ECOTROL HT additive has been modified to provide superior high shear stability minimizing polymer degradation for extreme HPHT applications.
When used in combination with the proper concentration and particle size of bridging agents for the formation drilled, ECOTROL HT additive improves the quality and thickness of the filtercake and reduces the spurt loss tested with the permeability plugging apparatus.
