Ven-BHC™ HT is an inorganic, synthetic gel-strength modifier and shale stabilizer designed for waterbased drilling, milling and completion fluids. Ven-BHC™ HT is a proprietary Poly Hydroxy Silicate technology. Ven-BHC™ HT provides borehole stability and superior hole cleaning for milling of casing and drilling highly deviated or horizontal sections as well as straight hole drilling applications. This fluid is especially effective when drilling unconsolidated, unstable, stressed or faulted formations.
The Ven-BHC™ HT drilling fluid system is capable of remarkable solids suspension, yet exibits extreme shear thinning flow characteristics. The result is a low-solids fluid system that drills like water, yet forms, almost instantly, a unique gel structure that carries and suspends cuttings in ‘near perfect transport’ while providing superior shale stabilizing characteristics.
Achieve higher Rates of Penetration, save on reduced drilling days. Has few system components and is easy to use. Works with Bentonite, Attapulgite and Sepiolite. Can be used with either Premium (untreated) bentonite or Peptized (treated) bentonite. Provides high yield point with low funnel viscosity. Has high ‘low end’ rheological properties.
Optimizes hole cleaningcapabilities, zero ‘slip’ velocity, has excellent suspension characteristics. Provides excellent shale stability Virtually zero shear stress at borehole. Maintains filtration control in the presence of contaminants. Minimize torque and drag. Environmentally safe fluid system. Requires no special or sophisticated rig equipment, just good solids control.
Solids and fluid are prevented from entering production zones (due to the bridging agents particle size distribution assuring a thin, low permeability filter cake Can be used with anionic fluid loss agents (PAC R
Treat water with soda ash to reduce hardness below 60 ppm (60 mg/l) to improve yield of bentonite. Pre-hydrate Premium (untreated) bentonite for at least one hour before adding caustic soda, mix Peptized (treated) bentonite for at least 15 minutes.
