Introduction to Artificial Lift

The global oil consumption market size has witnessed rapid growth in the last couple of decades owing to potential growth in the industrial and transportation sector. To meet such a high demand for hydrocarbon, many operators around the globe incessantly drilling to maximize their production. But in the existing wells, the reservoir pressure is not enough to produce fluids to the surface. Most of the wells in the world need some assistance to get the hydrocarbon to the surface. Various types of artificial lifts are employed according to properties of the well and availability of technology, which will subsequently growth of the global market in the coming years. Electric Submersible Pump ESP is a versatile technology and is broadly accepted in various parts of the world to enhance oil production.

What’s new in artificial lift?, Part 1

Artificial lift is a process used on oil wells to increase pressure within the reservoir and encourage oil to the surface. When the natural drive energy of the reservoir is not strong enough to push the oil to the surface, artificial lift is employed to recover more production. While some wells contain enough pressure for oil to rise to the surface without stimulation, most don't, requiring artificial lift. Even those wells that initially posses natural flow to the surface, that pressure depletes over time, and artificial lift is then required. Therefore, artificial lift is generally performed on all wells at some time during their production life. Although there are several methods to achieve artificial lift, the two main categories of artificial lift include pumping systems and gas lifts.

Artificial Lift Methods

Artificial lift refers to the use of artificial means to increase the flow of liquids, such as crude oil or water, from a production well. Generally this is achieved by the use of a mechanical device inside the well known as pump or velocity string or by decreasing the weight of the hydrostatic column by injecting gas into the liquid some distance down the well. A newer method called Continuous Belt Transportation CBT uses an oil absorbing belt to extract from marginal and idle wells. Artificial lift is needed in wells when there is insufficient pressure in the reservoir to lift the produced fluids to the surface, but often used in naturally flowing wells which do not technically need it to increase the flow rate above what would flow naturally. The produced fluid can be oil, water or a mix of oil and water, typically mixed with some amount of gas.

It seems that you're in Germany. We have a dedicated site for Germany. This book details the major artificial lift methods that can be applied to hydrocarbon reservoirs with declining pressure. These include: the sucker rod pump, gas lift, electrical submersible pump, progressive cavity pump, and plunger lift. The design and applications, as well as troubleshooting, are discussed for each method, and examples, exercises and design projects are provided in order to support the concepts discussed in each chapter.

Production rate is the combined impact of reservoir delivery and wellbore plus flowline multiphase flow pressure change. Six Primary Methods of Artificial Lift. Figure Examples of the primary methods of artificial lift. Gas lift is a natural flow process in that the reservoir pressure is the driving energy to push fluid to the wellbore, up to the wellhead, and into the surface facility. The wellbore, surface facility, and reservoir responses are the same for a natural flow well and for a gas lifted well. Purpose: To reduce the density of the flowing mixture of gas, oil, and water by increasing the gas-liquid ratio with gas injection into the tubing through a gas lift valve or orifice.

Artificial lift technologies are wide and varied. The term, artificial lift , applies to numerous tools, equipment, controls, instruments, computer hardware and software, technologies and techniques used to increase the flow of liquids usually crude oil, water or a mix of oil and water along with natural gas from a production well. The lift can be achieved mechanically through the use of a pump. Alternatively, lift can be achieved by decreasing the weight of the hydrostatic column in the well by injecting gas into the liquid at the desired depth. In this report, we discuss three categories of artificial lift systems: 1 pump-assisted systems; 2 fluid-assisted systems; and 3 flow enhancement techniques. Within these three categories, there are at least eleven types of lift technologies.

Drives for artificial lift

The challenges of producing and lifting unconventional oil and gas economically is no doubt the most daunting phase of unconventional oil and gas development. Slug flow, high free gas production, solid proppant, scale, paraffin , horizontal wellbore geometry, surface pad for multi-well in a cellar, and other unique unconventional wells problems are continuously testing the limit of our existing artificial lift systems. As it might be expected, this is invariably, affecting the economic viability of unconventional oil and gas production.

 Ну, доволен. Тот потерял дар речи. - Будь здоров, - сказал Беккер. Да этот парень - живая реклама противозачаточных средств.

Он потянулся к голосу. Или это его подвинули. Голос все звал его, а он безучастно смотрел на светящуюся картинку.

Сьюзан посмотрела на него и подумала о том, как жаль, что этот человек, талантливый и очень ценный для АНБ, не понимает важности дела, которым занимается агентство. - Грег, - сказала она, и голос ее зазвучал мягче, хотя далось ей это нелегко.  - Сегодня я не в духе.
