9. D&C Primary Focus Areas – 2007-2009

10. Business Unit Assessment Current Support Opportunities • Possibility of no new drilling activity until 2010 creates a threat of lack of support for non-rig activity, well remediation (T-4748), ordering of long-lead time materials, and bridging contracts to cover period. • Review current contracts during low-activity level for additional savings by eliminating unnecessary equipment and personnel / renegotiate rates. • Not all D&C contractors (who have a CVX IMA in place) have executed the Country-Specific Provisions for Kazakhstan. • Current WCS Sourcing Event evaluation matrix will consider IMA Amendments in place • Create blanket purchase agreements tied to IMAs for all equipment/material providers. • SM&I - Integration of suppliers into key processes • Establish additional Extended Enterprise agreements with D&C suppliers • Improve spend leakage (material orders going through Rig Contractor instead of TCO Warehouse) • Implementation of eProcurement and uploading contractor’s catalogs into Ariba • Establish effective Advance Supplier Relationship Teams at BU level with Strategic Suppliers • New contract in place with Nabors Drilling and Cameron. Both have rates tied to industry indices • New BPA in place with Sumitomo for CRA tubing with indexed pricing at time of P.O. placement • SLB, HAL, WTF, BHI, and BJ have a large support presence in the Caspian Region.
