Why Horizonal Drilling Methods Are The Most Effective

By Cynthia Reynolds


For those extracting oil or gas from the ground, the capacity to bore holes into these reserves is vital. They are usually under ground, on different strata and much that was found near the surface has been extracted. The need today for taking out fuel from the ground means that wells are deeper.

Much of the underground fuel reserves can be extracted using vertical well formations. But when these are found lying on opposite lines, horizonal drilling techniques must be used. The formation for these looks like a giant and exaggerated J, and it is most useful for drilling for gas reserves found in horizontal formations.

Firstly, the production crew will drill straight down until they reach the kick off point. This is when the well reaches the upper limit of a horizontal formation. The kick off is where the curvature of the J starts, because a straight angle drill is impossible to achieve physically with current technology but it is the most effective method possible under limited and often difficult circumstances.

The curvature is followed for some time until it reaches the entry point. This is the level at which the optimum amount of reserves will be extractable. From this point on, the drilling will become more and more along the flat plane angle of the gas or oil field that is being accessed.

Experts have long been looking for an alternative to the very costly vertical system. This requires drillers to locate many points where reserves are extractable and lay down a well on each point. Since this is only for one field, the newer method enables explorers to single out one main drill point and a few secondary ones to access everything that this field offers.

The complexity of the horizontal method is one drawback, but this is not very hard to do, so it is still effective and efficient compared to the traditional system. The engineering experts analyze the drill samples constantly to identify the points. As the rocks brought up show fuel, it will be near time for the drill manager to order kick off.

This is the level when the basic drill bit is replaced by a special configuration of bits. They are formed to bore the curve, which is a progression of smaller angles that create it, and there are different points to every well. This method of driving at multiple angles ensures that the correct levels are reached, or when the conventional drill is put on again.

The horizontal system has been found to be more efficient and productive than the vertical system in recent years. The technology for the former method came to be effective during the 1990s, and one oil and gas shale field uses it exclusively. Today, a lot more companies study the possibility of its use, and it has become the preferred option.

You can study the specific topic using the relevant search item on an online browser. This makes for better views and much good info. This technology is becoming the wave of the future, for oil and gas, energy and petrochemical concerns, allowing drilling companies that much more leeway and savings from cost reductions for single rather than multiple boring projects.
