Today's challenges of high-cost drilling, deep water and increasingly subtle traps demand that we get the interpretation correct. The need for accurate prediction of rock and fluid properties has led more than 40 oil companies worldwide, including all the super majors, to adopt RokDoc as an essential part of their exploration and development workflows. RokDoc provides graphical rock physics and rapid forward modelling for today's quantitative interpreter. User-friendly, versatile and rapid, RokDocallows users to explore, model and assess the impact of rock properties on the seismic response. By bringing rock physics into the mainstream workflows of interpreters, geologists and geophysicists, RokDoc places powerful predictive models for exploration and production into the hands of every user.
