Saudi Aramco to develop tight gas northwest fields
The national oil company (NOC) Saudi Aramco is on the verge to develop the tight gas fields identified in the northwest of the Kingdom to supply the gas-fired power plant required for the giant Maaden Phosphate City project currently under construction.
Since Saudi Aramco is re-injecting a part of the associated gas for enhanced oil recovery (EOR) to boost the crude oil production out of the maturing fields, any opportunity to develop non-associated gas should be explored.
This strategy applies to the unconventional gas for which Saudi Arabia is listed among the top five countries with 645 trillion cubic feet (tcf) estimated recoverable reserves of shale and tight gas behind China, USA, Argentina and Mexico.
In proportion, Saudi Arabia holds reserves more than twice unconventional gas than conventional gas.
For the last five years, Saudi Aramco put a major effort to evaluate this unconventional resources knowing that water availability shall be the limiting factor.
– Northwest of Saudi Arabia near by Turaif and along the border with Jordan
– South Ghawar as a side formation of the eponymous world largest crude oil field in the Eastern Province
– Rub Al-Khali in the south of the Empty Quarter
Since Maaden is investing $7 billion capital expenditure in the Phosphate City project, the Northwest tight gas fields are ideally located to power supply all the facilities to be installed at Waad Al-Shamal.
Saudi Aramco to feed SEC Waad Al-Shamal powergen
The Saudi Electricity Company (SEC) is planning a 1000 MW gas-fired combined cycle power plant (CCPP) supported by a 50MW solar power plant.
Each module will have a treatment capacity of 50 million cf/d of natural gas.
– 10 flowlines
– Control room
– Metering station
– Gas gathering center
Considering that the Saudi Electricity Company Waad Al-Shamal power plant and the Saudi Aramco Turaif tight gas field development projects should be awarded on early 2015, the Waad Al-Shamal gas central processing facility should start commercial operations by 2017.
