Selecting a drilling contractor for your well development may seem straightforward, but the reality is more complex. Engaging with the right contractor is crucial, especially if complications arise during the drilling process. In this article, we outline five essential questions to ask when evaluating drilling contractors.
1. What is your experience with this specific type of well?
Wells come in various types—mining, water, monitoring, and injection wells—and each has unique requirements regarding equipment, design, and regulation compliance. Not every contractor has the same level of expertise with all well types. Ensure that your contractor has sufficient experience with the specific type of well you require and can provide examples of related projects they have successfully completed.
For instance, a contractor who effectively combined air and mud rotary drilling with safety engineering controls helped a mining company save thousands by rehabilitating damaged production wells.
2. Do you have the appropriate drilling equipment?
Different projects require different types of drilling equipment. Some contractors may attempt to execute your project using equipment that may not be ideal. It's important to partner with a contractor that possesses a diverse array of drilling technologies, ensuring that they can select the best tools for your job.

3. How do you manage projects on limited access sites?
Some sites, such as those on steep terrain or within urban environments, may pose significant access challenges. When hiring a contractor, inquire about their strategy for drilling, maintaining, or rehabilitating wells in restricted access locations. The right contractor will have suitable equipment and the necessary experience for such conditions.
Moreover, they should be able to provide references for previous challenging projects they have successfully completed.
4. What is your process for unanticipated well conditions?
Upon arriving at the project site, contractors may discover that a well is in worse condition than anticipated. It is important to discuss contingency plans with potential contractors, such as alternative methods for rehabilitation or the ability to provide cost estimates for comparison with drilling a new well. A capable contractor will work collaboratively with you to ensure the best possible outcome.
5. Will you perform production testing?
Understanding the performance of your well—both during development and throughout its lifespan—is vital. Regular testing can reveal early signs of decline, providing an opportunity for rehabilitation rather than having to replace the well. After rehabilitation, testing also helps gauge the improvements gained from your investment.
What about production guarantees?
While it may be tempting to ask contractors for guarantees of production, this question can be misleading. Genuine contractors understand the inherent uncertainties in well development and rehabilitation. Rather than promises, they should offer educated estimates based on their expertise.
