High performance system promotes increased rates of penetration The unique chemistry of Baroid’s PERFORMADRIL® water-based drilling system provides for a high degree of clay control, wellbore stability, performance based rates of penetration, low coefficients of friction and rheological control over a wide range of temperatures. The versatility and clay control exhibited by this system has made it a high performance fluid that has become a credible replacement for invert emulsion fluids globally.
With its unprecedented technical performance, PERFORMADRIL system is an excellent choice for reactive shales, dispersive clays, no-salt formations, permeable sands, high pressure/high temperature wells and directional wells.
Compliant with the most stringent environmental regulaions In addition to being compatible with the most technically demanding wells, PERFORMADRIL water based system poses less risk to the environment and rig personnel than any other drilling fluid. Complying with the most stringent environmental regulations, PERFORMADRIL system has the highest environmental rating (GOLD) achievable in the North Sea and unlike competitive technology, it is non-toxic and biodegradable.
Qatar Shell Services Company (QSSC ) was planning to drill and core an 8½” reservoir section in an exploration well in the Pre-Khuff formation. The primary target was the Jauf Reservoir, and the Unayzah Reservoir was the secondary target. QSSC was seeking an environmentally-friendly fluid system that could help minimize formation damage and provide optimum shale inhibition for increased wellbore stability over an extended period of time during well logging. As an added challenge, the expected temperature in the reservoir section was expected to be 300°F.
Halliburton's Baroid Fluid Services has designed its high performance water-based drilling fluids to meet four basic criteria: extremely inhibitive, highly shear thinning, non-dispersed, and very low in colloidal content.
