The oil (gas) field development consists of two subprocesses, drilling and pro- <br /> <br /> <br /> <br /> <br /> duction where is treated as sequential in nature. Drilling is perfomed from <br /> <br /> <br /> <br /> <br /> platform in which one can drill only one well at a time, while production has <br /> <br /> <br /> <br /> <br /> a production level of uncertainty. In this final project we will construct a <br /> <br /> <br /> <br /> <br /> mathematical model for oil and gas field develompent process with two ap- <br /> <br /> <br /> <br /> <br /> proaches, deterministic and stochastic. For the deterministic case, drilling <br /> <br /> <br /> <br /> <br /> time for each well is considered to be equal, analogous for the produstion time. <br /> <br /> <br /> <br /> <br /> For stochastic case, time for drilling and production process follows a particu- <br /> <br /> <br /> <br /> <br /> lar distribution pattern. Using Renewal Theory, the completion of a well and <br /> <br /> <br /> <br /> <br /> failure to produce economical amount of oil or gas are analogous to the fail- <br /> <br /> <br /> <br /> <br /> ure of a componenty. The stochastic model is simulated for two distribution, <br /> <br /> <br /> <br /> <br /> exponential and gamma distributions. From this model we find a number of <br /> <br /> <br /> <br /> <br /> active wells at any time that is used to estimate the production rate in a field.
