Horizontal Drilling

Weatherby Energy makes use of many different techniques and methods in drilling to help maximize the chance of an investor return. To better understand what Weatherby Energy offers and some of the techniques available in the drilling industry, it is helpful to have a background in different practices used. One example of such a practice is horizontal drilling. Learning more about this technique can help you to better understand how Weatherby Energy can help you make your investment a success.

What is Horizontal Drilling?

Oil is not actually found in pools under the ground but is rather found in the holes in the rock, much like the holes in a sponge. Drillers need to get to the areas where there is the most abundance of oil. In the early years of oil production, drillers would simply scoot over a few hundred feet and drill again to collect more oil. This got to be a very expensive operation, until horizontal drilling became a more common practice.

Horizontal drilling is also referred to as horizontal directional drilling and is a term for drilling that is not vertical but at a slant. With directional drilling you save time and money, as a few holes are needed instead of many. This allows for Weatherby Energy to cover more potential ground when drilling for oil without a larger investment.

Horizontal drilling is used in situations where vertical drilling is too difficult or too expensive. It can be useful for drilling under certain preexisting structures, such as large buildings and roads, or natural barriers, like a lake or particularly hard rock formation. It can help determine the reasons for a well’s drop-off in performance. It is more efficient because the reservoir of oil is being penetrated at an angle so more oil will be available.

Benefits of Horizontal Drilling

There are many benefits that arise when Weatherby Energy uses horizontal drilling. First, environmentally, directional drilling is good because less holes means less disturbance of the ecosystem.

The main benefit of directional drilling, however, is the cost. Even though a single operation is more expensive than vertical drilling, you have to do less of them. The angle of drilling allows you to reach more areas to collect oil. For example, if you drill underneath a fault that is beneath a reservoir, you will pass through several areas where oil is plentiful. Also, if the oil is located in horizontal layers of rock, you will make contact with more of the surface area of the strata and therefore produce more oil. You also will not have the expense of moving the entire drilling rig on the surface as you can drill several holes from one central location. This can decrease expenses on land operations and offshore ones as well. The bottom line is horizontal drilling is more expensive that vertical drilling but more cost efficient, as much as 20 times more.

One other practical use of directional drilling is drilling a relief well to control the pressure from a blowout. Going at the wellbore at an angle will allow drillers to locate the trouble spot. Then they will inject a fluid to decrease the pressure that caused the blowout.

Horizontal drilling is widely accepted as the preferred method to recover oil and gas from reservoirs that are mainly horizontal in their strata and is a method used by Weatherby Energy in appropriate situations when best for investors. Many improvements have been made to this technology and the pipe that is used is flexible enough to wander about and get to oil that is in various locations. Some of the directional drilling starts as far away as six miles from the targeted location.
