The Ghawar Field is situated in the eastern part of Saudi Arabia, approximately 100 kilometers southwest of the city of Dhahran. It covers an area of over 2,700 square miles, making it one of the largest oil fields in the world. The field was discovered in 1948 by the Arabian American Oil Company (Aramco), and since then, it has been producing oil at an unprecedented scale. The Ghawar Field is estimated to hold over 70 billion barrels of oil reserves, which is roughly 7% of the world’s total oil reserves.
Geology of the Ghawar Field
The Ghawar Field is a complex geological structure that consists of multiple layers of rock formations. The field is located in the Arabian Basin, which is a region of extensive oil deposits. The primary reservoir rock in the Ghawar Field is the Arab-D reservoir, which is a layer of limestone and dolomite that dates back to the Jurassic period. The Arab-D reservoir is particularly significant because it has a high porosity and permeability, making it an ideal formation for oil production.
Structure of the Ghawar Field
The Ghawar Field is divided into five main reservoirs, each with its unique characteristics and production patterns. The reservoirs are separated by layers of rock that act as barriers, preventing the oil from migrating between the different reservoirs. The five reservoirs are:
The Arab-D reservoir, which is the primary reservoir in the Ghawar Field
The Arab-C reservoir, which is located above the Arab-D reservoir
The Arab-B reservoir, which is located below the Arab-D reservoir
The Arab-A reservoir, which is the shallowest reservoir in the Ghawar Field
The Hanifa reservoir, which is the deepest reservoir in the Ghawar Field
Production History of the Ghawar Field
The Ghawar Field has been in production since 1951, and over the years, it has produced billions of barrels of oil. The field reached its peak production in the 1980s, producing over 5 million barrels of oil per day. However, due to declining oil prices and increasing production costs, the field’s production has declined significantly since then. Today, the Ghawar Field produces around 3.8 million barrels of oil per day, which is still a significant portion of Saudi Arabia’s total oil production.
