CELLFOOD® Essential Silica Formula starts with highly purified mineral silica. Most silica products on the market today are in tablet form and are not as easily absorbed by the body. Silica comes in many forms and from many sources. Why our CELLFOOD® Silica Formula is the best Research show that silica counteracts the effects of aluminium on the body and therefore may be important in supporting neurological health. Silica and the brain: Silica levels decrease with ageing and therefore may be needed in larger amounts by the elderly. Silica and the heart: Research confirms that with age, silica disappears from the aorta, the heart’s key blood vessel – thus weakening its critical connective tissue, and resulting in a greater cardiac risk. Silica and the skin, hair, nails, teeth + gums: Research show that without adequate levels of silica, the body cannot maintain optimum skin elasticity, strong hair, nails, teeth and gums. Silica, along with other trace minerals found in this formula, may be used to strengthen bones and increase the body’s collagen production. Silica and the bones + joints: Calcium and Vitamin D alone are not sufficient for bone growth, density, strength, and flexibility. Silica supplementation can be an aid in supporting healthy bones, joints and cartilage, skin, nails, hair, teeth, gums and heart. Overall, this investigation supports the potential use of nanomaterials to enhance the inhibition capabilities and the long‐term stability of WBM for unconventional shales, presenting an environmentally friendly alternative for harsher environments.In our youth, our tissues absorb and maintain high levels of silica enabling our bodies to remain flexible, resilient, and energetic – but as we age, our silica levels steadily decline. Despite the high illite content of the Woodford shale, the NP‐WBM exhibited superior inhibition properties that reduced cuttings erosion and swelling effect by 24.48 and 35.24%, respectively, compared with the KCl/PHPA fluid. Also, NP‐WBM preserved 43.97% of its initial cuttings‐carrying capacity, whereas KCl/PHPA experienced a severe reduction of 95.24% at extreme conditions (250☏). The high thermal conductivity of NPs played a key role in promoting a nearly flat trend in the cumulative filtrate for the NP‐WBM at aged conditions, whereas KCl/PHPA suffered a dramatic increase. NPs exhibited high colloidal stability with ζ‐potential values less than –30 mV, which warrants their dispersion within the WBM at an optimal concentration of 0.75 wt%. The results of this investigation revealed that SiO 2‐NPs and GNPs acted synergistically with other additives to improve the filtration characteristics of the WBM, with only minor effects on the rheological properties. Conventional potassium chloride (KCl)/partially hydrolyzed polyacrylamide (PHPA) fluid was used for comparison purposes. Finally, chemical‐interaction tests, such as cutting dispersion and bulk swelling, helped to analyze the effect of introducing NPs on the inhibition capabilities of the WBM. In addition, dynamic aging was performed at temperatures up to 250☏ for thermal‐stability evaluation. NP‐WBM characterization included the analysis of the rheological properties measured with a rotational viscometer and the evaluation of the filtration trends at low‐pressure/low‐temperature (LP/LT) and high‐pressure/high‐temperature (HP/HT) conditions. The aqueous‐stability test and ζ‐potential measurements were used to assess the stability of the NPs. Characterization of Woodford shale was completed with X‐ray diffraction (XRD), cation‐exchange capacity (CEC), and scanning electron microscopy (SEM). The design of the nanoparticle WBM (NP‐WBM) followed a customized approach that selects the additives according to the characteristics of the reservoir. This research evaluates the potential of using silica (SiO 2) nanoparticles (NPs) (SiO 2‐NPs) and graphene nanoplatelets (GNPs) as drilling‐fluid additives in a single formulation to improve shale inhibition and long‐term stability of water‐based mud (WBM) against temperature effects. Although oil‐based mud can be used to achieve these goals, environmental and economic concerns limit its application. Drilling‐fluid design for shale plays aims to deal with the lack of wellbore stability associated with fluid‐invasion, shale‐swelling, and cuttings‐dispersion phenomena.
