The Adar oilfield, also known as the Adar Yale, Adar Yeil or Adaril field, is an oilfield situated in the Melut in South Sudan estimated to contain about 276 million barrels (43,900,000 m 3) of oil. The Chevron Corporation discovered the Adar Yale field in 1981, shortly before the start of the Second Sudanese Civil War (1983–2005). Soon after Chevron had suspended operations in .

The increased utilization of scanning electron microscopy (SEM) and associated elemental detection systems (, energy dispersive analysis of Xrays) has greatly expanded our knowledge of dispersed clay morphology and mode of occurrence in sandstone reservoir rocks.

In order to analyze the dynamic fracture responses of surrounding rocks in underground space to cyclic impact loads, a series of dynamic compressive tests were conducted using hollow cylindrical and intact sandstone specimens under confining pressures corresponding to 5, 10, and 12 MPa, and the hollow cylindrical sandstone were subject to radial gradient stresses. In .

Nubian Formation (NF) is a term which designates the weak rock formation in central, western, northern Sudan as well as neighbouring countries such as Libya, Egypt and Chad. These formations include sandstone, mudstone, siltstone, conglomerates and pebbles. As shown in Fig. (1), the Nubian Formation in Sudan covers about 28% of the total area ...

It occurs as the stone is heated and cooled or is wetted and dried. Lichens and other growths can also damage your sandstone, as they produce chemicals that break down the stone. It can also cause more cracks and holes to appear. Whilst it may seem impossible to prevent the effects of this sort of weathering from occurring, simply by sealing ...
