Safaniya Oil Field

Posted on Posted in oil fields

Oil is the most valuable commodity in the entire world. Being one of the most essential commodities in modern times, oil exploration and extraction has become a trillion dollar industry globally. Oil or crude oil is extracted from oil wells. A large area that has numerous oil wells situated in close proximity is referred to as oil-field. An oil-field can expand and cover very large areas, even spanning several hundreds of kilometers. In order to fully exploit the area, multiple wells are established, scattered over the whole oil field.

Introduction

The Safaniya Oil Field is the world’s major offshore oilfield located north of in The Persian Gulf. Estimated reserves are in the 37 billion barrel range, and current output appears to be 1.2 MBOD. The field started production in 1951.

The Safaniya reservoir is the main produce reservoir in the Safaniya Field, the major offshore oil field in the world. It lies within the of Middle Cretaceous Albian age, and was deposited in a fluvial dominated deltaic environment. The Safaniya is also Saudi Arabia’s primary supplier of heavy oil at an average API gravity of 27.The southern part of the field is dominantly thick, massive sands, while the northern part is more heterogeneous, with all types of sub-deltaic environments; distributary channels, mouth bars, crevasse splays and interdistributary bay shale’s, prodelta  shale’s, and shallow marine shale’s and sands.

Objectives

The main and important objective of this work was to build a 3-D model of electrofacies based on the 11-layer geologic description of the Safaniya reservoir in the Safaniya area. It was believed that the 11-layer 3D electrofacies model would help to better understand the heterogeneity of the reservoir, assist in making reservoir management decisions and developing multi-layer reservoir simulation models.

Oil-Fields are regions with numerous oil wells. In these fields, petroleum or crude oil which deception beneath the ground is extracted. Crude form of oil is sent to the refinery and processed for further use. Usually, several kilometers of area is covered by these oil reserves.

About Safaniya Oil Field Location

Saudi Arabia’s publicly owned oil and Natural Gas Company owns and operates the elephant-sized oil field, which was discovered in 1951 and has been producing oil since 1957. The field produces up to 1.5 million barrels of heavy crude oil per day.

Production

The main producing reservoir is the Safaniya which is cretaceous sandstone in the Wasia formation. Most geologists believe that the Safaniya field and the neutral Zone field share the same aquifer that continues toward Kuwait’s . The Safaniya field has several separate geologic production potential at depths between 4,000 and 7,000 feet. It was brought into production in 1957 at about 25,000 barrels per day. By 1993, there were a whole of 624 wells in the field. When Saudi Arabia’s oil making fatigued in 1980–1981, Safaniya was producing over 1.5 million barrels per day. Today the field still produces 600,000 barrels per day and almost all of Safaniya’s oil still comes from the Safaniya formation reservoirs.
