REDEFINING FLUID SYSTEMS
GageVis™ mixed metal oxide (MMO) viscosifier comprises highly cationic, high aspect ratio crystals that interact with the anionic surfaces of the bentonite platelets dispersed in water. This interaction creates the base slurry for the GageDrill™ viscoelastic water-based drilling fluid system. The combination exhibits the characteristics of a solid while static, and a watery liquid when subjected to minimal mechanical displacement.
- Allows minimal disturbance to mechanically weak formations
- Maintains circulation after initial losses through most loss circulation zones
- Exhibits exceptional hole cleaning and suspension properties, gelling instantly when shear is removed
- Breaks circulation with minimal shear
- Breaks over easily with chemical additions
- Runs with finer than normal shaker screens
The extremely versatile GageVis MMO viscosifier can be used effectively in myriad applications, including:
Mechanically weak/unconsolidated formations:
The GageDrill MMO system’s exaggerated flow regime transitions from typical low viscosity fluid flow at the drill pipe to zero flow at the wellbore. Under static conditions, the GageVis MMO/bentonite complexes or adducts associate with each other to create a pseudo-solid, thus allowing mechanically weak and mechanically unconsolidated formations to be drilled without major disturbance and frequently close to gauge. The system successfully drills unconsolidated sands, pea gravel and similar formations.
Lost circulation zones:
When drilling through the loss zone, the fluid moves beyond the wellbore, penetrating the loss path until, lacking mechanical disturbance, stops penetration. Without disturbance, the then elastic solid state will prevent further losses at that depth. The GageDrill system can be used to drill most types of lost circulation zones, including fractured hard rock, reefs and depleted reservoirs.
Reservoir drill-in fluid (RDF):
An appropriately designed and engineered GageDrill fluid creates an impermeable near-wellbore filter cake on permeable rock surfaces that prevents or reduces considerably the invasion of fines into the formation, thereby maximizing return permeability. Additionally, demonstrably low flow back pressures allow for very easy cake breakthrough.
The exceptional suspension and hole cleaning capabilities of the GageDrill MMO system prepare the casing for successful milling operations.
GageCon™ fluid conditioner is used to counteract the negative impact of anionics on the performance of the GageDrill™ mixed metal oxide (MMO) drilling fluid system.
GageTrol™ filtration control agent is a highly cross-linked substituted starch used as a fluid conditioner to reduce filtrate in the GageDrill™ mixed metal oxide (MMO) drilling fluid system.
