Abstract This work presents the development and validation of a multi- variate relation for the behavior of the water-oil-ratio (WOR) and/or water cut (fw) functions. This new model incorporates the reservoir and fluid properties for both phases (oil and wa- ter) and is based on the assumption of pseudosteady-state flow conditions.

The following steps outline how to calculate the Oil Water Ratio. First, determine the percentage volume of water (%). Next, determine the percentage volume of oil (%). Next, gather the formula from above = OWR = O/W. Finally, calculate the Oil Water Ratio. After inserting the variables and calculating the result, check your answer with the.

The water-oil ratio have an important impact on the structural properties of the samples. • Catalyst has the highest activity when water-oil ratio is 20. • The degradation ratio and the rate constant of RhB reach to 97.69% and 0.03253 min −1 in 100 min severally. • Because having small size structure, the largest specific surface area and so on.

The oil water ratio formula is simple: OWR = O / W where OWR is the oil water ratio, O is the percentage volume of oil, and W is the percentage volume of water. For example, if a mixture contains 40% oil and 60% water, the oil water ratio can be calculated as follows: OWR = 40 / 60 = 0.67

In terms of Waterdrive decline analysis, the Log (Water Oil Ratio) v's Cumulative Oil Production (or Np) to predict oil recoveries for water oil ratios (WOR) greater than 1 or watercut greater than 50% is commonplace. Therefore we have developed a simple routine to permit low, mid and high trend decline analysis of Log (WOR) v's Np relationships.

The oil/water ratio is 75/25. Example 1: Increase the oil/water ratio to 80/20: In 100 bbl of this mud, there are 68 bbl of liquid (oil plus water). To increase the oil/water ratio, add oil. The total liquid volume will be increased by the volume of the oil added, but the water volume will not change.

Ratio of the volume percent oil to the volume percent water in an oil mud, where each is a percent of the total liquid in the mud. OWR is calculated directly from the retort analysis of an oil mud. For example, if a mud contains 60 vol% oil and 18 vol% water, the oil percentage is [60/(60 + 18)]100 = 77% and the water percent is [18/(60 +18.

Water-oil ratio forecasting is an empirical analysis method; there is no formal model or equations. Plots of both water-oil ratio and water-oil ratio +1 are used in forecasting, and the plots are typically semi-log with cumulative oil production as the x-axis. Water-oil ratio, water-oil ratio +1, and water cut are defined below:

The principal reason for waterflooding an oil reservoir is to increase the oil-production rate and, ultimately, the oil recovery. This is accomplished by "voidage replacement"—injection of water to increase the reservoir pressure to its initial level and maintain it near that pressure.
