Oil and gas production water cut
The extraction of oil and natural gas through hydraulic fracturing — or fracking 1 — from the plains of southeast New Mexico and West Texas takes water. A lot of water. It also produces a lot of waste water 2. This waste water, called produced water 3 in the energy industry, is high in salt and toxic for human consumption. In September 2008, water broke through in the high permeability intervals in a well producing 500 bbl/d of oil, with 60% water cut. Oil production then decreased to 200 bbl/d. This production decline was the result of a high drawdown, the onset of water production, and the high clay content—including kaolinite— in the formation. Later Liu (1989) substituted the water cut with the ratio of cumulative oil production to cumulative water production in the model proposed by Ershaghi and Omoregie (1978). Warren (1998) reported a linear relationship between cumulative fractional flow and cumulative oil production. Almost 85% of the oil wells is producing with water cut more than 97%. Increasing water cut or even watered out phenomenon was frequently happen during production stage, some of this problem was happen after well intervention such as after pump replacement. Improved Oil Recovery. Primary production usually only recovers some 30 to 35% of the oil in place. Although the effectiveness of water injection varies according to the formation characteristics, a waterflood can recover anywhere from 5% to 50% of the oil that is remaining in the reservoir, greatly enhancing the productivity and economics of the development. A 45,000 bpd design production with gas and 40% water cut will give about 10 cubic meters from the wellheads per minute. There also needs to be enough capacity to handle normal slugging from wells and risers. This means the separator has to be about 100 cubic meters, e.g., a cylinder 3m in diameter and 14m in length at the rated operating pressure.

Water from the biggest Floating Production Storage and Produced water treatment is typically considered an upstream oil and gas (O&G) process. The treatment steps and a rough cut of TSS and free O&G.

While primary production refers to oil that is recovered naturally from a production, and the process becomes uneconomical when the water cut reaches the 90 to 99% level. (For example, water injection is never used on natural gas wells.).
Approach diagnoses, reduces water cut. Oil field operators have employed numerous treatment methods, both mechanical and chemical, to reduce water production rates.

However, most of the traditional models represent water cut as a function of cumulative oil production instead of production time. Note that cumulative oil production itself needs to be estimated or predicted. To this end, we derived a new model that correlates water cut and production time in oil reservoirs. Extraction of oil and gas from underground reservoirs often is accompanied by water or brine, which is referred to as produced water. As reservoirs mature, especially if secondary or tertiary recovery methods are used, the quantity of water climbs and often exceeds the volume of the hydrocarbons before the reservoir is exhausted. One of the biggest environmental and oil and gas production cost factors in the development of the U.S. shale basins is how the industry handles water. water cut. The term water cut, or water Water production. The present worldwide daily water production from oil wells averages roughly 3 BWPD per barrel of oil, although some wells produce significantly higher amounts. It costs money to lift water and then dispose of it. In a well producing oil with 80% water cut, the cost of handling water can double normal lifting costs. Produced water is a term used in the oil industry to describe water that is produced as a byproduct during the extraction of oil and natural gas.Oil and gas reservoirs often have water as well as hydrocarbons, sometimes in a zone that lies under the hydrocarbons, and sometimes in the same zone with the oil and gas.
