Documenting water (fluid) from dewatering process as the most strategic product in drilling operations in order to make fluid and improve its rheological properties in line with environmental standards for reuse of wastewater

Abstract

Drilling operations, like any other industrial activity, at the end of the operation employed dumps waste, wastewater to the environment, and if there is no planning for treatment and their elimination, in long-term this can have adverse effects on the environment. Assessment and recognition of the effects of drilling fluids is an acceptable and logical method for making a suggestion to reduce the probable injuries and damages resulting from the disposal and the drilling to the environment. In addition, one of the most important factors in reducing the negative environmental effects of waste is correct management. So that sometimes the cost required for the removal of pollution or controlling emissions of waste significantly decreases with proper and innovative management, and all the waste caused by the washing of the reservoir, well reservoirs, adjacent area of pumps and equipment related to wells enter water run-off and after entering into the storage basin, the solid settles there and its liquid phase enters dewatering to do operations and water treatment units. Moreover, at a later stage to decide whether dewatering water is appropriate for dilution or making clay or not, depends on the results of rheological water mixture and drilling fluid (1). If the desired mixture had appropriate rheological properties after treatment, dewatering water can be used. (According to the environmental standards of water reuse and wastewater returned in accordance with the agenda of the Technical Office of the Executive Vice President of Strategic Planning and Monitoring, suitable Dewatering Water is the one that does not make rheological change properties more than 50% in the of the fluid). In this study, a number of drilling machines will be used in defined projects to the amount of waste in order to make use of the standards and to improve the rheological properties of the fluid examine (Islamic Republic of Iran Iran's vice president of strategic planning and monitoring, the Office of Strategic Technical Assistance Administration, 2010).
