Mott MacDonald raises the bar, adds to project portfolio

The company is executing various projects for Occidental Oman and Mukhaizna, Oman Gas Company, Oman Oil and Daleel Petroleum amongst others, VINOD SHAH, managing director, Mott MacDonald Oman, tells K S SREEKUMAR

GLOBAL management, engineering and development consultancy Mott MacDonald feels its business in Oman is in good shape while it maintains steady growth year on year.

“Competition within the industry has increased recently following the mass entry of new players. With a very steady order book, there are also a number of projects pending award which would add to our current project portfolio,” says Vinod Shah, managing director, Mott MacDonald Oman, in an interview with OGN.

The outlook for the economy looks good, he says adding that the Oman government has indicated an increase in the oil and gas budget and has plans to investment in the industry over the next five years through a combination of government and private spending.

Mott MacDonald, which has been present in Oman for over four decades, predominantly works for national and international companies in the oil and gas, water and power sectors.

“However, we also work for various ministries and EPC contractors as well and have been appointed to many large and medium sized projects,” says Shah.

The company is executing various projects for Petroleum Development Oman (PDO), Occidental Oman and Mukhaizna, Oman Gas Company, Oman Oil and Daleel Petroleum amongst others.

At present, Mott is also associated with Khudairi Group, North Oil Company (NOC) in Iraq for developing a complete Greenfield Gas Compressor Station at Ajeel Oil Field and also providing engineering, procurement and construction services for a 32- inch bypass stream in Sohar GSS.

“We are technical adviser for the IWP extension at Sur; providing survey, design and drawing works for 33 kV at Royal Camps in Ghubrah; upgrade of crude export facilities at Daleel petroleum station and Construction Supervision for temporary power generation to Oman’s main interconnected system,” he says.

Excerpts from the interview:

How successful has your steam injection programme in Qarn Alam been? What is the nature of the job? How has it helped Petroleum Development Oman (PDO) in its EOR efforts?

The Qarn Alam Steam plant is a joint effort between PDO, EPC contractor (Dodsal Engineering and Construction LLC), Mott MacDonald and various suppliers working in a ring fenced environment and under one roof.

Mott MacDonald has been successfully using Business Information Modelling (BIM) on this project – use a single, shared 3D model, cultivating collaborative working relationships. This ensured focused approach on achieving best value while minimising structural clashes and allowing for a faster project delivery.

This approach encouraged all parties to share suggestions and observations at an earlier stage which helped in achieving a smooth commissioning process.

The steam increases the temperature of the oil trapped underground, reducing its viscosity and dramatically increasing output from horizontal wells. This project won the Engineering Achievement Award at the 2011 Oil and Gas Middle East Awards.

• Original field recovery rate: 3 per cent

• Expected recovery rate with EOR: 20-35 per cent

• Net oil production increase: 60,000 bpd

What are the new technologies that you have introduced in Oman for oil recovery?

Our experience on new technologies started with EOR experience on the Mukhaizna Facilities Development Project with Dodsal Pte Ltd. This project was developed by Occidental in Mukhaizna, South-Central area of Oman.

Right on the success of Mukhaizna project we were awarded the Qarn Alam Steam Injection Project (On Plot) with Dodsal Engineering and Construction LLC, which further strengthened our association with PDO.

The Qarn Alam field is a fractured carbonate reservoir with the oil highly viscous and very little of recovery is feasible by conventional oil extraction technologies. But with EOR techniques such as “Thermally Assisted Gas Oil Gravity Drainage” technique (TAGOGD) being deployed here it is possible to enhance the recoveries. Steam is injected directly into the fractures through a battery of steam injection wells, to heat the reservoir and lower the viscosity of the oil and make it flow easily into the reservoirs. Later our EOR Polymer Flooding experience was developed further on the Marmul Polymer Flooding Project, world’s largest and first full scale polymer project at Marmul in south Oman. On this project, we were responsible for the detailed design for EPC Contractor SNF Floerger.

How many projects are you executing for Petroleum Development Oman (PDO)? Which are they? Kindly provide the details?

You have been named owner’s engineer for the $350 million Ghubrah Independent Water Project (IWP) in Muscat? What is the nature of your work?

We are reviewing the contractor design of the new 42 MIGD seawater desalination plant. We will also supervise construction and the testing of the plant during the subsequent phases.

Our appointment adds to our involvement in major desalination plants not only in Oman but also across the Middle East. We were the technical advisor to the Government for the Sur IWP, which was the first in the country and set the precedence for future projects. We are currently advising Oman Power and Water Procurement Company on expansions to both Barka I and Sur IWP, as well as to Majis for the new 20 MIGD SWRO plant being constructed in Sohar.

We also carry out major design work for the Public Authority for Electricity and Water and much of the water supply system in Muscat has been designed by Mott MacDonald.

We’ve completed important studies including the Water Supply Master Plan back in 2004 and the Water Balance for Oman, completed earlier this year. At the same time, we are designing a new sewerage scheme for Suwayq and carrying out study and design work for Salalah Sanitary Drainage Services Company in Salalah.
