GEP Haynesville has completed four strong Haynesville Shale wells from two separate pads in northern Sabine Parish, La. The Bayou San Miguel Field discoveries are in Section 26-9n-12w. The highest producing well, #2-Alt Olympia Minerals 26-23HC, flowed 40.29 MMcf of gas and 763 bbl of water daily from acid- and fracture-treated perforations at 13,005-21,293 ft. It was drilled to 21,507 ft (12,761 ft true vertical) and tested on a 33/64-inch choke with a flowing casing pressure of 8,481 psi. The horizontal lateral bottomed within 2 miles to the north in Section 23. The offsetting #1-Alt Minerals 26-23HC produced 39.845 MMcf of gas daily from perforations at 12,894-20,875 ft. It was drilled to 21,088 ft (12,763 ft true vertical) with a lateral extending about 1.5 miles to the north. Within 2 miles to the north-northwest in Section 23-9n-12w, #1-Alt Olympia Minerals 23-26HC flowed 31.182 MMcf/d of gas from perforations at 12,910-22,482 ft and was drilled to the south to 22,450 ft (12,766 ft true vertical) and bottomed in Section 26. It was tested on a 32/64-inch choke, and the flowing casing pressure was 8,566 psi. The  #2-Alt Olympia Minerals 23-26HC flowed 37.599 MMcf/d of gas from perforations at 12,961-22,252 ft. It was drilled to the south to 22,450 ft (12,766 true vertical) and bottomed in Section 26. Tested on a 32/64-inch choke, the flowing casing pressure was 8,566 psi. GEP is based in The Woodlands, Texas.

2 Angola

Eni drilled and tested #3-Agogo, the second appraisal well of the Agogo discovery in offshore Angola Block 15/06. Results from the test increased the estimated size of it by approximately 40% to 1 Bbbl of oil with further upside to be tested in the northern sector of the field. The test also indicated a production capacity of more than 15 Mbbl/d of oil. The appraisal well was drilled to 4,321 m, and it is about 4.5 km northwest of #1-Agogo. Water depth in the area is 1.7 km. The #3-Agogo encountered 120 m of net pay in Miocene and Oligocene sandstones. Testing also showed that #3-Agogo is in communication with #2-Agogo reservoirs and the further extension of the Agogo discovery to the north. Block 15/06 partners are Rome-based operator Eni (36.84%), Sonangol (36.84%) and SSI Fifteen Ltd. (26.32%).

3 Saudi Arabia

Saudi Aramco received regulatory approval to develop the Al-Jafurah unconventional gas field in the Eastern Province. Al-Jafurah lies between Ghawar Field and Qatar in the ad Dahna desert. There are three conventional source rock intervals - Tuwaiq Mountain, Hanifa and Jubaila - within the basin’s Jurassic petroleum system. The volume of gas resources in the field is estimated at 200 Tcf of rich raw gas, which will provide the petrochemical and metallic industries. The Dhahran-based company expects field production to start in 2024. By 2036, it is estimated that approximately 2.2 Bcf/d of gas could be produced, with approximately 425 MMcf/d of associated ethane, which is about 40% of the company’s current production. Aramco also expects the field to produce approximately 550 Mbbl/d of liquids and condensate.
