“…The Jafurah Basin, delineated east of the giant Ghawar oil field, harnesses one of the largest unconventional gas fields in Saudi Arabia, with an elliptical outline measuring 170 km long and 100 km wide (Figure 1). The wet gas window in the Eagle Ford shale play-the second largest shale gas in the United States-is considered a close analog for the Jafurah Field [11]. All unconventional carbonate wells require multi-stage fracturing as part of the completion strategy.…”

This study provides a workflow and preliminary estimations of the estimated ultimate recovery (EUR) volumes for natural gas and condensate liquids in the Tuwaiq Mountain Formation, the principal target in the Jafurah Field development project in Saudi Arabia. The strategic need for the field development is reviewed and the field characteristics are outlined based on public data sources complemented with data from analogous reservoirs. The target zone in the Jafurah Basin is a carbonaceous shale, being developed with up to 10,000-ft-long multistage-fractured laterals with 30 ft perforation cluster spacing and an assumed typical 1250 ft well spacing. The field will come on stream in 2024, when the gas-gathering pipeline system, natural gas processing plant, and underground gas storage facilities will all be in place. The range of uncertainties in the key reservoir parameters is taken into account to estimate preliminary EUR volumes (P90, P50, and P10) for both gas and condensates. Based on the present and prior EUR estimations, it can be concluded that the Jafurah Basin comprises one of the largest unconventional field development projects outside of North America.

“…Scholars have conducted much research on how to improve gas drainage during mining and developed plenty of drainage methods such as gas drainage through surface wells, 9,10 gas drainage through drilling, 11 gas drainage by roadways, 12 fracturing technology, 13 and gas drainage in goafs. 14 The traditional single gas drainage method cannot achieve good effects due to the multiple and complex gas emission sources 15 in highly-gassy coal seam mining. In recent years, 'high (low)-level' roadway collaborative gas drainage technology has been proposed in the Yangquan mining area in China.…”

Coalbed methane (CBM), which is extremely rich in deep coal reserves in China, is not only the material cause of gas explosion and coal-gas outburst disasters but also a clean and environmentally friendly energy source. Gas drainage must be carried out during deep coal mining to avoid gas accidents while obtaining clean energy. The low-level roadway is an effective gas drainage measure for coal seams with high coal-gas outburst risk and low-permeability, and it can simultaneously realize the functions of gas drainage before and during mining. Roadway tunneling has a strong influence on the stress and permeability properties of the adjusted coal seams, and further determines the gas drainage efficiency and the layout of the air-return roadway. Taking the Pingshu Coal Mine as an example, this paper analyzes the influence of the vertical distance between the low-level roadway and the underlying coal seam, and the influence of the width and height of the low-level roadway on the stress relief and deformation characteristics. The results indicate that the low-level roadway tunneling results in a nonuniform stress disturbance of coal seam #15. And a reasonable layout and size parameters of the air-return roadway in coal seam #15 were proposed based on which gas drainage practices were carried out with good effects in panel #15211. The research can effectively guide the elimination of coal and gas outburst in return air roadway, and achieve the purpose of safe and rapid tunneling coal roadway under the environment of highly-gassy coal seam.
