Bore Construction and Completion Optimisation (Bore Design)

After the bore is drilled the next stage is completion and clean up to maximise the output of the bore to its full potential. This clean-up process is critical in making sure that the project is getting value for money.

Surtech Systems can help you make the most of the logs and supply the necessary information to guide:

  • Screen placement and design to access the aquifer of interest
  • Calculate volumes for gravel packing and grouting of casing
  • What are expected returns and the correct pump and completion design

Our team can ensure you have the information you need to make informed decisions now and in the future. Logs and data are supplied in an easy to use and integrate with your workflows.

Client Challenge

The client was installing a series of bores into a well know aquifer as part of a managed aquifer recharge scheme. The high volume bores were critical to the scheme, and the client needed a better understanding of the formation so that the well completion design was optimal for the formation, and would perform as expected. Previously bores of this nature would take a long time to clean up without any metric to determine whether the bore was ready for production. The client wanted a suite of logs to help them answer this question and many more.

Our Solution

Surtech Systems ran a suite of logs to help the client answer the many questions the client had from volume of gravel pack and grout needed, through hole volume calculations to expected bore performance. High end tools like the Borehole Magnetic resonance tool was used to obtain a hydraulic conductivity log. The data from the BMR log was then used as a benchmark for expected bore performance, after completion and the clean-up phase of the bore. Having this benchmark allowed the client to make an informed decision on when the clean-up process was completed, and when the bore was ready to go online. This validation process, combined with other techniques implemented within the drilling program, saw a large reduction in total clean-up time for each bore.
