  1. Gas Condensate Rate Equation A worked example to demonstrate the use of the gas condensate rate equation to estimate well productivity, taking account of condensate blockage. The data will be taken from a Sensor simulation model to allow comparison with simulation results.

  2. Statement of problem (1) A well in a lean gas condensate reservoir has with these properties kh = 1,000 md ft rw = 0.33 ft re = 3000 ft Mechanical skin = 0 Average reservoir pressure = 3965 psia Wellbore flowing BHP = 1545 psia Lean gas condensate (PVT properties on next slide), flowing OGR = 26 stb/MMscf ‘Rock’ rel perms, with Corey exponent of 3 (data on slide 4) Assume oil saturation = 1% outside near-well region These conditions correspond to this Sensor simulation case after 3 years (1095 days) 10 md, rock rel perms

  3. Statement of problem (2) • Estimate the maximum gas production rate for the well. • Estimate the condensate blockage skin

  4. Gas-Oil Relative permeability

  5. PVT properties Dew point pressure of fluid with OGR = 26 stb/Mmscf = 3734 psi
