Finding the Right Location for Oil and Natural Gas Drilling

Finding the Right Location for Oil and Natural Gas Drilling : Using several different geological methods, Alfaro Oil and Gas is able to discover what locations contain the highest amount of shale rock underground. After an oil company has selected the right location for drilling ...

When considering the perfect well location selection, it is important that the geographical and topographical land attributes of the land is evaluated in order to determine if the site location is the best place to extract the highest amount of shale oil or natural gas possible, notes Alfaro Oil and Gas. There are some cases where you will be able to drill multiple wells in one singular well pad. This is very convenient to both the drilling company and the environment because of the ability to draw out resources using one single pad.

After an evaluation has been completed, it is time to place the well pad as well as the access roads so that the operational requirements may be balanced so that all of the necessities required to begin the drilling process will be met. Using several different geological methods, Alfaro Oil and Gas is able to discover what locations contain the highest amount of shale rock underground. This helps to guarantee that you get the most out of your well location as you possibly can. You should invest your money wisely and be sure that you locate your well pad in a rich shale rock area.

Once the location has been chosen and the well pad or pads have been set, the drilling process is ready to begin. First, there is a small surface rig that uses air to drill the shallowest part of the well. The surface casting is set and cemented off in order to seal the shallow completely. It is then time for the larger rig to be set up so that drilling can begin in the lateral section of the well. The horizontal method of drilling may be used in order to get to rocks that are located in hard to reach places.

After an oil company has selected the right location for drilling with the assistance of a geologist or geophysicist, signed all necessary paperwork for a lease, title or right of way access, it is time to begin the oil drilling preparation process, explains Brian Alfaro of Alfaro Oil and Gas. The crew begins by clearing off the land and making sure that it has been leveled and all accessible roads have been built. Since water is a priority when it comes to drilling, it is very important that there is a source of fresh water nearby the location. If there is no natural water source in the area, a water well will need to be drilled.

After the water situation has been solved, the crew will then dig a reserve pit that is used to dispose of any rock cuttings or drilling mud that may occur during the process. The reserve is lined in plastic so that the environment will remain protected in case the oil site is in an ecologically sensitive location like a marsh. If this is the case, the mud and cuttings will need to be disposed of at an offsite location to prevent any type of further harm.

After the land has been prepared, the crew digs several holes in order to make way for the rig as well as the main hole. A rectangular pit that is known as a cellar will be formed around the location of the drilling hole to provide a convenient work area to store drilling accessories and any other necessities that may be required.
