Case Study: Well Construction Performance Shaves More Than Eight Days Off of Plan in Rumaila Field

Solution optimizes drilling time while lowering costs

CHALLENGE – Halliburton was challenged to design, drill, and deliver wells in the Rumaila field – and to do this safely, efficiently, on time, and within the allocated budget. The geology in the field presented significant obstacles, including losses within naturally vuggy or fractured formations, challenges of drilling through highly reactive shale sequences with borehole instability issues, and depleted formations at critical points within the well geometry. These conditions, which tend to slow drilling with associated problems and historically increase the total well time, required proper engineering to overcome these challenges.

SOLUTION – To reduce drilling time and well costs, the Halliburton Project Management team developed plans and procedures, implemented from lessons learned on previous campaigns, that would deal efficiently with anticipated downhole issues. Halliburton Consulting and Project Management (CPM) created a synergy between all groups involved in the well construction, including Halliburton product service lines (PSLs) and third parties, in order to deliver the well objectives by applying practical solutions.
