Water Treatment and Wastewater Recycling Plant in Oil and Gas Production

WATERMAN ENGINEERS AUSTRALIA

Introduction

Water is a critical component in oil and gas processing, playing a crucial role in various stages of exploration, production, and refining. However, water handling in such processes poses serious challenges, mainly in connection with treating high TDS and salinity water. The situation is even more serious in oilfield sites, gas field sites, and exploratory sites where the need for water recycling and treatment is always necessary to minimize the impact on the environment and to keep operational costs at a minimum.

The oil and gas industry has seen a growing concern toward water treatment and recycling. These processes underline the sustainability of operations, license to operate, and low environmental footprint. This paper discusses the roles water treatment plants can play in mitigating the problems of high TDS and salinity during oil and gas production by recycling and reusing water to minimize waste and environmental harm.

The Water Challenges in Oil and Gas Production

Water finds its application on a large scale in the oil and gas industry for several purposes, such as in drilling, hydraulic fracturing, cooling, and hydrocarbon processing. The water used in these aforementioned processes frequently comes into contact with a wide array of contaminants, among which are hydrocarbons, heavy metals, several various chemicals, and high concentrations of dissolved salts. This contaminated water, often referred to as produced water, produces a great environmental risk if not properly treated.

Produced water typically contains high TDS concentrations, including salts, minerals, and other dissolved solids. Reservoir location and depth can make the salinity of this water vary widely. For many produced waters, these TDS values are very high and not suitable for direct discharge or reuse without treatment. The presence of salts and other dissolved solids can result in scaling, corrosion, and other operational problems of equipment, pipelines, and storage vessels.
