The problem of undesired water production is one of the most serious issues confronting the oil industry. Fractures, solution channels, near water zones, high permeability zones, fractures connecting water aquifers, and heterogeneous oil-water contact all increase the likelihood of early water breakthrough in a well. Once the problem of undesired water production in a well begins, it grows and becomes extremely difficult to regulate. Because of its low viscosity and high mobility, water can bypass oil, reducing the amount of hydrocarbon formation. This undesired water output grows over time and can consume the entire wellbore section, accounting for more than 90% of total production. Several mechanical and chemical water shut-off jobs are available. Several water shut-off jobs, both mechanical and chemical, are employed to reduce undesired water production, but implementing these techniques at the precise point of water breakthrough downhole is extremely challenging. Furthermore, these procedures have a lower possibility of success and are not trustworthy in stopping water output for an extended length of time.

Optimizing oil well production is very necessary nowadays.As oil prices are moving high, very few new oil reservoir discoveries and environmental norms leads us to think for optimizing production from wells. optimizing a well production based on previous workover history, production history and future operational and maintenance aspects is very important.oil well having crude containing paraffin and asphaltene may cause various production related problems. scale deposition is one among them which is very serious and care must be taken to prevent it.scaling of tubing is a very serious issue which oil and gas industry is facing today. scaling may lead to serious disaster which is loss of money and life of a well. This book discusses about a new technology to overcome this loss and enhance oil production thus, minimizing the operation and maintenance cost. Plunger assisted intermittent gas lift technology will minimize scale and paraffin deposition and also enhance oil production from a well. With help of this technology low gas injection rate is required which will increase the profitability from an oil well
