WebbThe equation above captures reservoir boundary conditions in which the total vertical stress remains constant (overburden above the reservoir does not change) and there is no change of lateral strain , a condition also termed as “uniaxial strain” deformation.Such condition is appropriate in long and thin reservoirs with a compliant caprock (Figure 3.19). http://www-naweb.iaea.org/napc/physics/FEC/FEC2012/papers/806_PDP820.pdf

WebbStress is the average force per unit area that a particle of a body exerts on an adjacent particle, across an imaginary surface that separates them. The formula for uniaxial normal stress is: where σ is the stress, F is the force and A is the surface area. In SI units, force is measured in newtons and area in square metres.
