Chevron announced that its 50% owned affiliate Tengizchevroil has safely commenced operations at its Wellhead Pressure Management Project, or WPMP, at the Tengiz oil field in Kazakhstan. TCO achieved this milestone by converting its first metering station at Tengiz to low pressure and activating the associated Pressure Boost Facility, or PBF. This marks important progress for TCO's overall expansion project at Tengiz. The WPMP is designed to maintain the existing processing plants' full capacity by lowering the flowing pressure at the wellheads and then boosting the pressure to the existing plants.
