Tuwaiq

Jabal Tuwaiq (Arabic: جَبَل طُوَيْق, Tuwaiq Mountain) is a narrow escarpment that cuts through the plateau of Najd in central Arabia,[1] running approximately 800 km (500 miles)[2] from the southern border of Al-Qasim in the north, to the northern edge of the Rub' al Khali desert near Wadi ad-Dawasir in the south.

In the framework of the recent Saudi tendency to promote entertainment, a group of 100 young hikers joined Tuwaiq Mountains Challenge in February, 2019.

This study was a first step towards building a quantitative 3-D geologic model for use as an analog to the lower Arab-D reservoir.

High-precision laser scans were used as a template upon which stratigraphic interpretation were made allowing researchers to characterize sub-seismic, flow-unit scale reservoir properties of Jurassic bioherms in an effort to better understand optimum production techniques of this enormous reservoir.
