Drilling for Offshore Oil and Gas - Africa and Middle East

Datamonitor, August 2010, Pages: 159

The report analyses the regional offshore drilling market in the Africa and Middle East region providing historic drilling and spending trends in the period 2005 to 2009 and forecast trends over the period 2010 to 2014. The report discusses key drilling events in each country of the region including a synthesis of shallow versus deep water spending and exploratory versus development spending.

Scope

- Insight on the drilling services market and its evolution in the current market environment from both an operational and expenditure perspective.

- Forecasts of the number of wells to be drilled and the likely level of expenditure required to fulfil predicted levels of activity

- An overview of drilling equipment and processes and a description of how the associated technologies are costed and allocated to various well types.

- Analysis of individual offshore areas and their role in the future growth of the drilling sector and rig market.

Highlights of this title

Global offshore drilling activity will be fully recovered by 2011. It will stabilise in 2010, will return to growth in 2011 and will grow rapidly in the subsequent two years.

A rounded total of 1,430 wells were drilled offshore the Middle East from 2005 to 2009, with 98% in the Gulf, almost all of which were development wells. Around 2,000 exploratory and development wells are forecast over the next five years.

"Over the last five years it is estimated that nearly 2,500 shallow water wells were drilled in the region. Meanwhile around 1,150 deep
water wells were drilled. Over the next five years it is forecast that around 3,170 shallow water wells will be drilled accompanied by around 1,310 deep water wells."

Key reasons to purchase this title

- Develop a drilling investment strategy targeted around Exploration and Production hotspots.

- Evaluate likely technology driven growth opportunities created by the medium term evolution of the drilling sector.

- Analyse how drilling spending patterns will vary between different technology sectors and geographies over a five-year forecast period.
