    Abstract: An apparatus for generating a giant electrorheological (ER) effect includes an upper high voltage electrode and a lower high voltage electrode, the upper high voltage electrode and the lower high voltage electrode each covered with a water-absorbing material and have water absorbed thereon. The apparatus also includes a fluid channel formed by layers and positioned in a gap between the upper high voltage electrode and the lower high voltage electrode; a pressure sensor positioned at one of the high voltage electrodes; a pump to flow silicon oil through the fluid channel; and a high voltage source configured to apply a voltage to the upper high voltage electrode. A method for generating a ER utilizes the apparatus.

    Abstract: Electrorheological fluids and methods include changes in liquid-like materials that can flow like milk and subsequently form solid-like structures under applied electric fields; e.g., about 1 kV/mm. Such fluids can be used in various ways as smart suspensions, including uses in automotive, defense, and civil engineering applications. Electrorheological fluids and methods include one or more polar molecule substituted polyhedral silsesquioxanes (e.g., sulfonated polyhedral silsesquioxanes) and one or more oils (e.g., silicone oil), where the fluid can be subjected to an electric field.

    Abstract: In a method for drilling, completing and fracturing a subterranean formation, an electrical potential is applied to oil or synthetic based drilling fluid to increase the viscosity of the fluid and enable the fluid to entrain drill cuttings and proppant. The same base fluid may be used for drilling, completion and fracturing by adjusting the electrical potential and consequently the viscosity of the fluid for the particular application. In fracturing, little or no potential is applied until the fluid enters the zone of the formation to be fractured. High potential is then applied at the fracture point of the formation to effect fracturing and to enable the fluid to transport proppant into the fracture.
