Better understanding of the mode of interaction of the PHPA additive with clay particles in drilling fluids has been achieved by in-depth analysis of the effect of various concentrations on rheological and filtration properties of drilling fluids. This allows industry to work with optimal PHPA concentrations for more efficient drilling.
Enhancing the rheological properties and shale inhibition
Five different drilling mud systems namely potassium chloride (KCl) as a basic mud, KCl/partial hydrolytic polyacrylamide (PHPA), KCl/graphene nanoplatelet (GNP), KCl/nanosilica and KCl/multi-walled carbon nano tube (MWCNT) were prepared and investigated for enhancement of rheological properties and shale inhibition.
Low Damage Polymer (Clay-Free): fluids treated with demulsifiers, enzyme breakers, surfactants, and acid blends that are tailor-matched to individual reservoir characteristics, helping to mitigate formation damage when drilling open-hole (barefoot) completion wells.

Conducted a research to determine the effect of using nanoclay powder when absorbed with partially hydrolysed polyacrylamide (PHPA) at increasing weight concentrations under 250藲F in terms of rheological properties, mud cake thickness, filtrate loss and shale swelling properties.

Spacer fluids - Atlantic Richfield Company
Spacer fluids providing an effective buffer between drilling fluids and cement slurries during well completion. The spacer fluids comprise a sulfonated styrene copolymer dispersant and one or more additional components such as surfactants, viscosifiers and weighting materials to form a rheologically compatible fluid between the drilling fluid and the cement slurry.
With a unique wettability characteristic which lowers the potential for Bottom-Hole Assembly (BHA) balling, OBF-LUBE HP contains no hydrocarbons and is compatible with all water-base fluids, including mono-/divalent brine fluids. With minimal contribution to the rheological properties of mud systems, OBF-LUBE HP does not foam and...
- What is high-purity aluminium?
- High-purity aluminium is a niche product, but although the production of 4N purity (99.99% Al) and above represent only 0.25% of the global primary aluminium produced, it is a material that is used in more and more applications, in the electronic domain (mainly for capacitor), energy storage industry, specialty alloys, and computer technology.
- How is high-purity aluminum produced?
- The high-volume and industrial production of high-purity aluminum follow two main routes: three-layer electrolysis and fractional crystallization. While both processes can individually reach 4N8 purity, higher purity levels can be obtained when employing them in series.
- What is the purity of aluminum?
- The purity of aluminum obtained by this method can finally achieve up to 4N8, with the main residual impurities being a few ppms of Fe, Si, Zn, Mg, and Cu . This method has been reported to achieve between 4N8 and 5N, starting from metallurgical-grade aluminum (2N8). This represents an overall impurity reduction factor of up to 99.5%.
- Can high-purity aluminum be used in integrated circuits?
- Such characteristics grant the usage of high-purity aluminum in integrated circuits, replacing Cu and Au as bonding wires for transistors, where thin films of high-purity aluminum are able to find applications as interconnecting lines in very large-scale integrated (VLSI) circuits [5, 6, 7].
