项目摘要
Heavy oil represents about 15 percent of world hydrocarbon reserves, and up to 70 percent of total world**hydrocarbon reserve if including extra heavy and bitumen. Majority of the oil production in Canada is from the**Western Basin with the dominant of oil sands/bitumen and heavy oil. Various techniques have been in place to**develop these enormous resources and can broadly be classified in thermal (steam-based flooding and**non-thermal methods (chemical-based flooding).**The production of Lloydminster heavy oil has its long tradition dated back to the early 20th century. The oil**gravities are considerably low, ranging from 10 to 12 deg. API, and in the promising range for non-thermal**Enhanced Oil Recovery (EOR) applications. Carbon dioxide (CO2) gas is present in the atmosphere at a**concentration of 0.03 percent and has been used for decades in the oil and gas industry for EOR. For most of**the petroleum applications, CO2 exists either as a gas or as a supercritical fluid, i.e., a fluid with the density**close to that of a liquid but volume-filling like a gas. Considering the Lloydminster reservoir pressure (500 psi)**and temperatures (15 deg. C), the CO2 likely exists in the gas state where it may undergo dissolution with oil**resulting in oil swelling, oil-viscosity reduction and vaporization of intermediate to heavy components. The**objective of this proposed study is to visualize the CO2/oil interactions at reservoir conditions. A series of**laboratory experiments are to be conducted in a custom-designed cell with oil samples taken from the**Lloydminster formation. The experimental results give more clues on 1) The interactions at the CO2/oil**interface and volume changes at reservoir conditions, and 2) Asphaltene precipitation as a result of CO2**dissolution in oil.**The results of this research will offer the industry an alternative to enhance the oil production in the**Lloydminster formation and ultimately contribute to reducing greenhouse gas emission.
重油约占世界碳氢化合物储量的15%,如果包括特重和沥青,则高达世界碳氢化合物总储量的70%。加拿大的大部分石油生产来自西部盆地,主要是油砂/沥青和重油。为了**开发这些巨大的资源,已经有了各种技术,大致可以分为热法(基于蒸汽的驱油)和**非热法(基于化学的驱油)。**劳埃德明斯特重油的生产可以追溯到20世纪初。石油重力相当低,从10度到12度不等。API,并在非热力**提高采油(EOR)应用的前景广阔的范围内。二氧化碳(CO2)气体以0.03%的浓度存在于大气中,几十年来一直在石油和天然气行业用于提高采收率。在大多数石油应用中,二氧化碳要么以气体的形式存在,要么以超临界流体的形式存在,即密度接近液体的流体,但体积像气体一样充满。考虑到劳埃德明斯特储油层压力(500磅/平方英寸)**和温度(15℃)。C),二氧化碳可能以气体状态存在,在这种状态下,它可能会与石油发生溶解**导致石油膨胀、石油粘度降低和中间到重质组分的蒸发。这项拟议研究的**目标是可视化油藏条件下二氧化碳/石油的相互作用。一系列的实验室实验将在一个定制设计的储油池中进行,样品取自劳埃德明斯特地层。实验结果提供了更多的线索:1)CO2/油界面的相互作用和在油藏条件下的体积变化;2)CO2在油中溶解导致的沥青质沉淀。**这项研究的结果将为该行业提供一种提高**劳埃德明斯特地层石油产量的替代方案,并最终为减少温室气体排放做出贡献。
