What is intelligent completions?
Intelligent completions incorporate permanent downhole sensors and surface-controlled downhole flow control valves, enabling you to monitor, evaluate, and actively manage production (or injection) in real time without any well interventions.
What advantages can intelligent completions offer?
Moreover, intelligent completions provide other important advantages such as production from several formations, zonal isolation, control of production rate from different intervals, and enhancement of artificial lift efficiency.
What is a smart well?
A smart well is a well which has equipment that can be controlled either automatically or by an operator at a remote location. Called smart wells, these downhole systems include the usual completion equipment but add valves, chokes, sensors, and actuators that are remotely monitored by both humans and software.
What are completion tools?
Completion equipment are those equipment which are used to bring an oil well to the completion state so that first test production and later on commercial production can be started from it.
What is Multilateral well completion?
Multilateral completion systems allow the drilling and completion of multiple lateral boreholes within a single mainbore. This allows for alternative well-construction strategies for vertical, inclined, horizontal, and extended-reach wells. Multilaterals can be constructed in both new and existing oil and gas wells.
What are the types of well completion?
Completions can be divided into three categories: open hole completions, liner completions, and perforated casing completions. In most wells, conventional single perforated casing completions are used; however, multiple, alternate, or slim hole completions may be used under certain conditions.
What is method of well completion?
Well completion incorporates the steps taken to transform a drilled well into a producing one. These steps include casing, cementing, perforating, gravel packing and installing a production tree. The first step in completing a well is to case the hole.
What is well completion design?
Well completion is defined as a single operation involving the installation of production casing and equipment in order to bring the well into production from one or more zones (Perrin, 1999).
What is a lateral well?
Lateral wells, commonly called drainholes, are high-angle holes drilled radially, usually horizontally, from the primary wellbore into the pay zone to increase contact with the reservoir.
Why multilateral wells are better than typical horizontal wells explain it?
Multilateral technology is very attractive for heavy oil applications. The incremental production over single horizontal wells is in general greater than 70%. This advantage is because multilaterals provide greater reservoir contact in low-productivity reservoirs.
What is the main purpose of well completion?
Well completion is a series of steps–depending upon the completion method–performed after the drilling and casing phase, that enable to well to produce hydrocarbons. The primary goals are to stimulate the well to maximize production, and running tubing to enhance the well’s lifespan and ease of maintenance.
What is meant by well completion?
hOW many types of completion are there?
What are the methods of well completion?
There are many factors that influence completion design:
- The well’s purpose.
- The environment.
- Drilling.
- The reservoir.
- Production.
- Completion techniques.
What is a deviated well?
A well with an inclination other than zero degrees from vertical.
What is horizontal well completion?
The horizontal well completion with stinger is usually used to control the bottom water cone. Although the pressure profile and the inflow profile along the horizontal wellbore can be divided into two parts by the stinger, these profiles have not really flattened.
What are stacked lateral wells?
Figure 2: Stacked laterals are in the same vertical plane; opposed, or gullwing, laterals are in the same zone but run in opposite directions; and fishbone, herringbone, or whalebone patterns are created by numerous laterals that extend outward from a single horizontal main bore to cover the zone.
What are horizontal wells?
What Is a Horizontal Well? A horizontal well is a type of directional drilling technique where an oil or gas well is dug at an angle of at least eighty degrees to a vertical wellbore. This technique has become increasingly common and productive in recent years.
What are well completion activities?
Well completion incorporates the steps taken to transform a drilled well into a producing one. These steps include casing, cementing, perforating, gravel packing and installing a production tree.
What are the types of completion?
What is a strat well?
“Stratigraphic test well” means any well or hole, except a seismograph shot hole, drilled for the purpose of gathering information in connection with the oil and gas industry with no intent to produce oil or gas from such well.
What is a sidetrack well?
In the context of horizontal wells, an additional wellbore drilled away from an original vertical or horizontal wellbore is a sidetrack. A sidetracking operation may be done intentionally or may occur accidentally.
What are the new techniques in well completion?
Some new technologies have been developed for horizontal well sand control completion in recent years, including “mud cake” cleaning technology, screen top cementing technology, casing-outside gravel packing sand control technology.
What are the different types of horizontal wells?
Types Of Horizontal Wells
- Long-Radius.
- Medium-Radius.
- Short-Radius.
- Tangent.
- Combination.
What is a horizontal Drainhole?
Horizontal Drainhole is the portion of a Horizontal Well drilled within the Field Interval that includes Take Points. Sample 1. Horizontal Drainhole means the portion of a well bore drilled laterally into a common source of supply for production or injection purposes.
