The Benefits of Using Surface Drillngtooling

Surface drilling, also known as open-pit or open-cast drilling, is a method used in mining, quarrying, construction, and geotechnical engineering to extract minerals, rocks, or other materials from the earth's surface. The process involves drilling holes into the ground to access and extract valuable resources or to gather geological data for engineering purposes. Here's an overview of how surface drilling works:

1. Site Preparation: Before drilling begins, the site is prepared by clearing vegetation, removing topsoil, and leveling the ground to create a suitable working area for drilling equipment and personnel.

2. Selection of Drill Rig: Surface drilling operations utilize various types of drill rigs, depending on factors such as the depth of the hole, the hardness of the rock, and the required drilling method. Common types of drill rigs include rotary, percussion, and rotary-percussion rigs.

3. Drilling Process:

Drill Setup: The drill rig is positioned at the designated drilling location, often on a stable platform or drilling pad. The rig's mast is raised to a vertical position, and stabilizing legs or anchors are deployed to secure the rig in place.

Hole Preparation: The drilling process begins with hole preparation, where the drill bit is lowered into the ground to create a pilot hole. The pilot hole serves as a guide for subsequent drilling operations and helps maintain drilling accuracy.

Drilling Operation: Once the pilot hole is established, the drill rig continues drilling to the desired depth using rotary, percussion, or rotary-percussion drilling methods. During drilling, the drill bit rotates and applies downward force to penetrate the rock or soil formation.

Cuttings Removal: As the drill bit advances, it generates rock cuttings or soil fragments that need to be removed from the borehole to facilitate drilling progress. Cuttings are typically flushed to the surface using drilling fluid (mud) circulated through the drill string or by air or water jets.

Sampling and Logging: At regular intervals, drilling may be paused to retrieve core samples or conduct geophysical logging to gather information about the subsurface geology, mineral composition, and structural characteristics.

Monitoring and Control: Throughout the drilling process, various parameters such as drilling depth, penetration rate, torque, and fluid circulation are monitored and controlled to optimize drilling performance and ensure safety.

4. Completion and Wellbore Stabilization: Once the desired depth is reached, the drill string is removed from the borehole, and casing may be installed to stabilize the wellbore and prevent collapse. Cement may be pumped into the annular space between the casing and the borehole wall to provide additional support and seal off groundwater zones.

5. Post-Drilling Activities: After drilling is completed, the site may undergo reclamation and rehabilitation efforts to restore natural habitats and minimize environmental impacts. Depending on the project requirements, additional activities such as blasting, blasting, or mineral extraction may follow surface drilling operations.

Overall, surface drilling plays a vital role in resource extraction, geological exploration, and infrastructure development, providing access to valuable resources and essential data for various industries. Efficient and safe drilling practices are essential to maximize productivity while minimizing environmental and safety risks.

Many operators use full-size rigs for surface spaced drilling. They sometimes find it easier or more convenient than getting a fit-for-purpose solution because they already work with a service provider and have all the equipment at the well site. However, this decision ended up costing them - in terms of expense, personnel and environmental exposure.

As we've seen in the oil and gas industry, one of the key indicators of performance is environmental sustainability. Whereas profitability and revenue used to be the way to measure an organization's success, stakeholders are now also considering an organization's environmental impact to assess its success.

Customers, employees, investors and the media are looking at the choices oil and gas organizations are making regarding their environmental impact - and they want to know what actions companies are taking to reduce their environmental footprint.

One of the ways we support our customers who want to make a positive impact on the environment is through our top hole drilling rigs. Full-size rigs are designed to build wells with a total depth of more than 20,000 feet. They are large machines designed for large jobs, so they have a significant environmental impact. When you use an open-hole rig instead of a full-size rig for top-hole drilling, you can increase operational efficiency and reduce your environmental impact.

Surface drilling rigs use less fuel

For surface borehole construction, you need a surface drilling rig. These rigs are highly engineered and designed for drilling surface sections and running surface casing.

Because of their small size, surface rigs require less fuel to run. 

They burn up to 50% less diesel fuel and therefore produce fewer emissions. In contrast, larger full-size rigs require more fuel and burn more fuel, thus releasing more emissions into the environment.

By reserving full-size rigs for their intended use, operators can drill more wells with fewer full-size rigs. This reduces transportation emissions from transporting additional full-size rigs in the field, while also reducing overall operating costs.

Surface drilling rigs require fewer personnel

Full-size drilling rigs typically require 16 personnel to operate successfully. In contrast, an open pit rig requires only nine.

When it comes to environmental impact, the number of people on the well site matters. 

More personnel require more trucking, which can release emissions along their route. In addition, more field personnel means more waste generated per shift. By reducing the number of field personnel, oil and gas operators can also reduce transportation emissions and waste generation.

In addition to the environmental benefits of fewer field personnel, there are considerable safety benefits. Fewer people means less risk of injury and accidents. In fact, JCDRILL is a leader in worker safety, with a goal of zero safety incidents, equipment damage and environmental impact every day. We provide safety tools and training for all personnel - both on and off site - so we can maintain a strong safety culture with our team.
