Horizontal Directional Drilling is the method used to increase production and hit targets that cannot be reached with a vertical drill. Most wells drilled for water, oil, natural gas, information, or other subsurface objectives are vertical wells drilled straight down into the earth. When horizontal directional drilling is combined with hydraulic fracturing, some rock units which were unproductive when drilled vertically can become fantastic producers of oil or natural gas. Horizontal Directional drilling has been used to reach targets beneath adjacent lands, reduce the footprint of gas field development, increase the length of the pay zone in a well, deliberately intersect fractures, construct relief wells, and install utility service beneath lands where excavation is impossible or extremely expensive. Perhaps the most important role that horizontal drilling has played is in the development of the natural gas shale plays.
Horizontal drilling activity took off in the 1980s. Presently, the oil and gas industry benefits from the multiple advantages of outfits like Americom’s horizontal directional drilling division as a reservoir development tool.
Horizontal wells are beneficial to reservoirs for multiple reasons:
- They may reduce water and gas coning and, as a result, reduce any remedial work necessary in the future.
- They have much more surface area in the pay zone, effectively increasing reservoir production rate several times over.
- They lower the pressure drop as well as the fluid velocity around the wellbore, therefore reducing sand production.
- They have a more efficient drainage pattern which increases the overall recovery of oil and gas reserves.
Condensing these advantages into a simple statement, horizontal drilling makes way for the efficient production of oil and natural gas. Hence, it reduces the overall time and cost it would normally take to achieve this.
Horizontal wells also have an edge over vertical wells for a number of reasons:
They can reduce the pumps from a treatment system, effectively warranting minimal cleanup of residual contamination and hot spots. As a result, they reduce site maintenance costs.
Unlike multiple vertical wells which require additional costs for trenched conveyance lines, a single horizontal well has an integrated conveyance line that you no longer need to connect with others.
Horizontal wells vary in length and depth. So, installation is possible in multiple locations (e.g. under buildings, landfills, ponds, pipelines, roads, runways, wetlands, and other surface obstructions). Additionally, Americom’s horizontal drilling streamlines the treatment system and conveyance lines. Hence, maintenance is easier and more cost-effective for the site operator or owner.
Given all these advantages, it is obvious why Americom’s horizontal drilling division is surely winning over the industry.
