In unconventional shales, unstable formations consist of the sedimentary rock made from clay and other minerals. During the drilling phase, sloughing shales can cause caving of the formation or, in some instances, the equipment to get stuck. ClayBrake™ Series Innospec Oilfield Services offers a series of proprietary cationic clay shale stabilizers designed to prevent swelling […]
Corrosion affects almost every part of a well’s lifecycle. In the drilling phase, well casing can corrode due to oxygen within the drilling mud. Innospec Oilfield Services offers a variety of water-soluble and oil-soluble corrosion inhibitors that are specially designed for use in water and oil-based drilling muds and air mist/stable foam operations. Drill-COR DC-305 […]
Liquid emulsifiers are widely used in all types of drilling fluid systems. They provide a host of benefits including emulsification of two immiscible fluids, wetting of solids for improved compatibility with drilling fluids and fluid loss control. Tensul™ Innospec’s Tensul Liquid Emulsifiers are designed to work as a system to provide maximum emulsification stability of […]
Wellbore instability caused by depleted zones or weak formations in maturing fields has led to considerable expenses due to lost circulation. Mitigating these expenses should not be complex; it only requires a change in approach from reactive to preventative. Innospec Oilfield Services is an industry leader in lost circulation solutions — offering a wide range […]
During the hole cleaning application, sweeping agents are added to the drilling fluid to assist with cleaning out left over drilling cuttings. Innospec Oilfield Services offers proprietary synthetic fiber solutions that are proven cost-effective in any situation and designed to specifically to your parameters. STRATA-KLEEN® STRATA-KLEEN is a proprietary treated synthetic fiber that provides superior […]
As operators drill deeper horizontally through the formation, pressure loss through the drill bit and drill pipe increases, the pump pressure must increase to maintain consistent flow. As this occurs, equivalent circulating density (ECD) increase and applies additional pressure on the formation. To keep ECD down, pressure management must be optimized to minimize the risk […]
