For an oil field in the south of Texas, USA, where a vertical well is drilled to a maximum depth of 10,000 ft, the average specific gravity and pore pressure gradient are given as 2.3 and 0.38 psi/ft, respectively. Using Avasthi equations for vertical and horizontal stresses, and assuming the Biot's constant and poisons ratio as 1 and 0.28, respectively, calculate the vertical and horizontal in situ stresses for surrounding rock formation at the bottom of the vertical well.
