Scr and rqd
WebThe rock quality designation (RQD) is a modified core recovery measurement (Deere and Deere, 1989). For each interval, the total length of all core pieces longer than 10 cm (4 in) as measured along the core centerline, should be determined and recorded as shown in Figure 2.

Accordingly, RQD enables core logging as well as evaluation of the degree of jointing along the core drill hole, the so-called “core run”, whereby RQD gives an average measurement of the degree of jointing along the total core run length
WebApr 1, 2024 · On the other hand, rock quality designation (RQD) has been considered as a valuable parameter for defining the one-dimensional (1D) jointing degree in addition to core recoveries such as total core recovery (TCR) and solid core recovery (SCR). WebApr 9, 2024 · Steel catenary risers (SCRs) are an efficient solution to transfer hydrocarbons from deep-water seabeds to floating facilities. SCR design requires an assessment of the fatigue life in the touchdown zone, where the riser interacts with the seabed, which relies on reliable estimates of the SCR–seabed stiffness over the design life.
