Directional well Applications

 Directional drilling has become a very important tool in the development of oil and gas deposits. Current expenditures for hydrocarbon production have dictated the necessity of controlled directional drilling to a much larger extent than previously. 

Probably the most important aspect of controlled directional drilling is that it enables producers all over the world to develop subsurface deposits that could never be reached economically in any other manner. 

In this module a number of topics will be covered that must be understood by the directional driller. The various types of wells and applications of directional wells will be touched upon along with well profiles and  planning



Application of horizontal drilling


 Application of horizontal drilling

The reservoirs that maybe considered as possible candidates for horizontal drilling are 

1-Reservoirs that may have potential water/gas-coning problems

2-Tight reservoirs (permeability << 1 millidarcies [md])

3-Natural vertically fractured reservoirs.

4-Economically inaccessible reservoirs.

5-Heavy oil reservoirs.

6-Channel and reef sand reservoirs.

7-Coal bed methane reservoirs.

8-Thin reservoirs.

9-Layered reservoirs with high dip angle.

10-Partially depleted reservoirs.

The Blowout Preventer


A blowout preventer is a large, specially designed valve that is mounted on top of the well during the drilling and completion stages of operation. The operator can close this valve to stop the flow of oil or gas in case of emergency.


The Blowout Preventer, or BOP, is safety equipment designed to prevent uncontrolled flow of formation fluids during drilling and completion operations. During drilling, mud is pumped down the drill string to lubricate and cool the bit, and provide equalizing pressure in the well. If the well’s hydro-static pressure falls below the formation’s pressure, a kick can occur, allowing gas, oil, and salt water fluids to enter the well bore.


During a kick, these pressurized, combustible, hydro-carbons can be pushed up the well bore to the surface, where they may potentially blow out the well and ignite. The BOP has the capability to control this flow by sealing off the well bore in several ways.


The Blowout Preventer is comprised of four main components, stacked one upon another. They are the annular preventer, blind ram, blind shear ram, and the pipe ram. There can be many different configurations, sizes and pressure ratings, dependent on well design, formation pressures, and areas of use. The BOP is attached to the steel casing that is cemented around the well bore. The drill string is suspended through the center of the well bore. This is the rotating pipe to which the drill bit is attached.


The first BOP component is the pipe ram.





During a kick, this ram is activated and creates a seal between the well bore and the outside of the drill string. The next component is the blind shear ram. If a kick occurs, it may become necessary to sacrifice the drill string to stop the flow of material inside of the well bore. The blind shear ram performs this function by cutting, or shearing the drill string, and sealing the well bore. The blind ram is used to seal the well bore when there is no drill string in the well. The annular preventer is a device that can seal around any object in the well bore, or upon itself. It is designed to create a seal, with or without the drill string present.
