The opportunity is an innovative technology that will revolutionise the measurement of oilconcentration and other impurities in produced water.Produced water is water trapped in underground formations that is brought to the surfacealong with oil. This results in harmful oils & contaminants being dumped into theenvironment that include crude oil carcinogens e.g. Xylene and Benzene - as well as theunnecessary loss of valuable oil.Approximately 2450 bn gallons of produced water are generated pa worldwide - by far thelargest volume of waste stream associated with oil exploration and production.It has been in contact with the hydrocarbon-bearing formation for centuries - it contains someof the chemical characteristics of the formation and the oil itself. May also include waterfrom or injected into the reservoir, and any chemicals added during the production &treatment processes. The physical, chemical properties of produced water varies considerablydepending on the location, the geological host formation, and the type of oil being produced.Produced water properties and volume can also vary throughout the lifetime of a reservoir.The nature of the problem is that the cost of managing produced water is a significant factorin the profitability of oil production.Also, in order to dispose of produced water economically and with the least environmentaldamage it is essential to be able to accurately measure the oil & contaminants present inproduced water. This is also vital so that process control can be monitored and optimised andto determine whether any oil can be extracted from the produced water.The problem with existing measurement technology is that, being lighter, any oil will rise tothe top of the process flow thereby missing any oil in water measurement devices. Themonitors will under measure oil content and over estimate the true efficiency of theseparation process – these measurements can be wildly inaccurate.

机会在于一项创新技术，它将彻底改变采出水中含油浓度和其他杂质的测量方法。采出水是被困在地下地层中的水，与石油一起被带到地面。这导致有害的油和污染物被倾倒到环境中，包括原油致癌物质，如二甲苯和苯，以及不必要的宝贵石油损失。全世界大约产生了24500亿加仑的采出水，这是迄今为止与石油勘探和生产相关的最大废水量。几个世纪以来，它一直与含烃地层接触——它包含了地层和石油本身的一些化学特征。也可能包括来自或注入到储层的水，以及在生产和处理过程中添加的任何化学品。采出水的物理、化学性质因地点、地质主地层和采出油类型的不同而有很大差异。在油藏的整个生命周期中，采出水的性质和体积也会发生变化。问题的本质是，管理采出水的成本是影响石油生产盈利能力的一个重要因素。此外，为了经济地处理采出水，并尽量减少对环境的破坏，必须能够准确测量采出水中的油和污染物。这对于监控和优化过程控制以及确定是否可以从采出水中提取油也至关重要。现有测量技术的问题是，由于重量较轻，任何油都会上升到工艺流程的顶部，从而错过了任何水中油的测量设备。监测仪会低估油含量，高估分离过程的真实效率——这些测量结果可能非常不准确。
