A core, 2.13” in diameter and 30“ in length, has been recovered
Question
1. A core, 2.13” in diameter and 30“ in length, has been recovered from a 5,000ft deep sandstone. In order to run a point -load test, ten 3”long cores have been cut. The Following failure loads (in psi) were obtained: 3,420 ; 3,150 ; 2,950 ; 3,280 ; 2,825 ; 3,410 ; 2,780 ; 3,050; 2,950 ; and 3,310. Estimate the
Young’s modulus
2. A well is drilled in an oil zone, where the pressureIs above the bubble point. This shaly-sandstone formation has the following given conditions:
Rw = 0.05 Ω m, Rt = 5 Ω m, Rsh= 1 Ω m, Φe = 0.18 .Using given equations to estimate the oil saturation, assuming (1) Vsh is negligible, (2) Vsh = 0.25
