...Odeh Ali Abstract About 50 mi south-southwest of the Hassi Messaoud field, a group of three fields, El Agreb, El Agreb Northeast, and El Gassi, is located in separate structural highs on the faulted El Agreb–El Gassi anticline which is on the same major pre-Hercynian anticlinorium as is Hassi...

... the source beds, but the black, commonly carbonaceous Silurian-Devonian shale which subcrops a few miles southwest may be presumed to be the source, as it is for Hassi Messaoud and the El Agreb and El Gassi fields. Magloire noted that Carboniferous strata wedge in to the north, lying unconformably...

... in the Hassi Messaoud and Rhourde El Baguel fields, whereas the Early Ordovician Hamra quartzite provides reservoirs in the Brides, Gassi El Adem, and Nezla fields. The Silurian, which consists of graptolitic shales grading upward to shales and sandstones, is overlain by coarse sandstones of Devonian...

... in 1968 to improve production. SN REPAL tested oil in the Lower Triassic in the Nezla North 2 well (central Sahara) not far from the large Gassi Touil field. At Gassi El Adem 1, SONATRACH tested gas at a rate of 50,000 Mcf/d from the Ordovician Hamra sandstones (central Sahara). In the Fort Polignac...

... into the Paleozoic section. In the area around the Rhourde el Baguel structure, all of the post-Ordovician section, including the Silurian and Devonian source rocks, was eroded. Further west, well penetrations in the Hassi Messaoud and El Gassi fields show that the Hercynian unconformity cut all the way down...

... million metric tons in 1960 to 8.18 in 1961. After a long delay, the El Agreb-El Gassi (S.N.P.A.) and Ohanet (C.E.P.) fields were put into production during the year. As to natural gas, the giant Hassi R’Mel field was put on production after the completion of the pipeline to Oran and Algiers...

Most production was at Hassi R’Mel (2,446,293,000 m 3 ) and the rest was from the Alrar East and North in Amenas gas fields. By J...
