Periodic Well Test Process

FOCUS: Improve well test for accuracy and capacity


A major oil exploration and drilling company realized that improvements to their periodic well test process were required to increase test accuracy and overall test capacity.


A Lean Six Sigma improvement team was formed to analyze the process and implement appropriate changes. The team identified potential improvements to improve test accuracy and efficiency. Several lean approaches were utilized. As a result of their efforts:
– Test accuracy was increased by 25%.
– Decision processes for well work were significantly improved.
– The capacity for the number of tests per month was increased by 423


Significant annualized ROI benefits were realized, including $400,000 in better well work decisions and $100,000 in the value of extra test capacity.
