HomeNOC Measurement Guidelines: Middle East

Introduction

A state-owned National Operating Company (NOC) established in 1974 in one of the Middle East oil rich states, responsible for all phases of the oil and gas industry engaged with KELTON to produce measurement guidelines.

The NOC’s strategy of conducting hydrocarbon exploration and new projects is through Exploration and Production Sharing Agreements (EPSA) and Development and Production Sharing Agreements (DPSA) concluded with major oil and gas companies such as ExxonMobil, Shell, Total, Occidental, Maersk and others investing in the country.

Timeline

  • April 2011—The NOC publish a tender looking for a consultancy firm to prepare hydrocarbon measurement guidelines.
  • August 2011—KELTON receive a letter of award from the NOC to begin the preparation of guidelines.
  • April 2012—Contract variation is issued to KELTON to include Multiphase Metering and Sulphur as this was not in the original scope.
  • February 2013—Final issue of the guidelines and contract close.

Relationship

The NOC and KELTON worked together to prepare the guidelines with considerable feedback and comments from the NOC and joint venture operating companies to be incorporated into the document. The guidelines were issued and are now the benchmark for flow measurement. It is likely that in the near future a revision of the guidelines will be carried out and this will be based on feedback from all stakeholders.

Testimonial

"After competitive tendering, we were delighted to leverage on the KELTON experience to prepare a set of measurement guidelines to ensure our world class practice in measurement compliance and integrity." - Head of Products Measurement
