  • Cased Hole Log Evaluation
  • Well Cost/Time Estimates
  • Concept screening and full field development

Recent optimisation work:

  • On a recent coring job with a major international drilling company Aztech Coring Optimisation services assisted with improvements, 3 x 36m cores were cut with each having 100% recovery in a field that has never been able to fill a core barrel.
  • Aztech coring optimisation was asked to conduct an after action review (AAR) between a major drilling company and coring service provider. This independent AAR resulted in uncovering major operational errors including poor pre job planning faults from both parties that contributed to coring failures. The Aztech AAR findings have changed the way both parties now approach coring operations and pre job planning. Quote from the drilling company is that “we wont core again without Aztech being involved in our coring operations” this is from very beginning of pre job planning, pre job load out of equipment, monitoring the coring real time at the rig site and a follow up AAR.
  • Regularly brought in to compile cost comparisons between coring service providers and conduct a rig time line of coring operations to give the drilling companies an accurate cost estimate of the entire coring operation.
  • Written technical tendering documents for major operators in Australasia. This has saved the drilling company substantial time and cost savings that will be seen for the duration of the tender and ongoing operations.
