“…A number of authors have discussed correlations between the petrographical and mechanical properties of common rocks such as granite, sandstone, limestone, shale, etc. (see, for example , Bell 1978;Sachpazis 1990;Ghafoori et al 1993;Ulusay et al 1994;Shakoor and Brown 1996;Topal and Doyuran 1997;Bell and Lindsay 1999;Tugrul and Zarif 1999). The present study reports data on core samples collected from 19 wells in the Krishna-Godavari (K-G) and Cauvery basins, both onshore and offshore.…”

The petrophysical and mechanical properties of reservoir rocks from two major basins on the east coast of India were studied using samples cored from 19 wells in the Krishna-Godavari and Cauvery basins. Several of these drill holes are located in the producing oil®elds in these basins. The purpose of the study was to investigate the relationships between the properties of the rocks including dry density, effective porosity, uniaxial compressive strength, tensile strength and Young's modulus. Their relationships are further elucidated using regression analyses. The results indicated that the petrophysical and geomechanical properties vary widely for the different sedimentary rocks and basement samples related to their depth and geological age. It is emphasized that the work should be further extended to assess its full potential in reservoir studies of the oil®elds in these basins.

“…The effect of water content on the strength of soft rocks and shales has been outlined by a number of researchers (Ghafoori et al, 1993;Greene and Schaffer, 1997;Lashkaripour, 2002). Accordingly, the test results of Edwards Limestone exhibit trends similar to those shown in Figure 5-6.…”

“…The third method adopted in this study is averaging values based on water content because water content is generally known as a significant factor affecting the strength of shales (Ghafoori et al, 1993;Greene and Schaffer, 1997;Lashkaripour, 2002). The test results were re-arranged into six groups based on water content, and the averaged values were plotted in Figure 6-19.…”

“…From all the UCS test samples, it can be said that the percentage decrease in Qu value at 30 minutes of drying is 23%, 60 minutes of drying is 41%, and 90 minutes of drying is 59%. This can be attributed to research conducted [9], that the compressive strength (Qu) of clay shale decreased by 55.02% during the first cycle of the drying wetting process. After going through the second cycle, the Qu value has decreased by 70.41%.…”

Clay shale has unstable properties even though it is on a slope having a gentle slope. This raises many geotechnical problems. This study aims to determine the effect of clay shale drying on compressive strength and durability reduction by using samples taken from Kandangan Village, Polisiri Village, Bawen Sub District, Semarang Regency and Central Java. The drying process simulates when the open cut excavation process is exposed to sunlight, such as road excavations and bored pile excavations. The method used is testing the physical property, property of rocks and mechanical property with drying at intervals of 0 minute, 30minutes, 60minutes, and 90minutes. Initial condition of sample had 23 percent -31 percent of vulnerable water content. The influence of drying can reduce the value of water content; clay shale is really easy in creating the weathering; and all samples of shale clay have very low durability properties. Of all the UCS test samples, it can be said that the longer the drying, the greater the percentage of qu value loss. For testing Modulus Elasticity can be said that the longer the drying, the greater the percentage of loss of E50 value and Etan value. The relationship between UCS and Modulus Elasticity (E50 and Etan) values with the duration of the drying is the longer the drying the greater the lost value of UCS and Modulus Elasticity.
