This paper is a review of the techniques that have caused a large improvement in drilling and completion performance on the Goodwyn A Platform North-West Shelf, Australia. The collective effort of Well Construction professionals using these techniques has resulted in the drilling of a 6263m (20,550’) TD well with a horizontal step out of 5200m (17,060’), at a tangent angle of 67° in 39 days from spud to well handover. This was 31% under P50 AFE time estimate.

The paper will describe a method to produce systematic, steady and sustainable improvements to Well Construction operations. The methods described are a way of harnessing the collective brainpower of Well Construction professionals and focus that energy towards rigorous analysis of problems or areas of potential improvement, then systematically working through and implementing solutions.

The Technical Limit methodology and Performance Improvement Groups (PIGs) are best suited for complex, high cost drilling projects, typically ERD developments, high cost MODU exploration or subsea operations.

In addition, other tools such as Hazard Management, Learning System and Planning Processes which contributed to success are explained.
