U S A lax 01-214-952.9435 Abstract A course of exercises has been developed that trains the student in the different steps involved in discovering and evaluating the economic worth of an oil field. The objective is for the course to act as a link for several different aspects of petroleum engineering -seismic analysis, drilling and completion, logging, well testing, reservoir evaluation and economic analysis -that the student has been taught in detail in the specialist courses that he/she has attended during the course of hidher petroleum engineering education.To do this, a fictitious oil field has been invented, and its details incorporated into a simulator that allows drilling, logging and other operations to be carried out so tiat the student gradually learns about the properties of the field during the course of a series of "hands on" exercises. Once the investigation is complete, the student has enough information to make an economic evaluation of the field, and is in a position to determine the necessary economic criteriainvestment required, net present value, return on investment etc. -that will allow the "company" owning the lease to decide whether to go ahead with developing the field.

An Improved Drilling Simulator for Operations, Research and Training

“…Successful application requires the use of offset well data. The simulator has been developed not only for operation but for training as well [8,9]. Verification of good predictions was done through use of lab generated data [10], while Kelessidis et al, in a series of articles [11,12,13] have demonstrated that the simulator could be used with sufficient accuracy to simulate the drilling process, provided that proper monitoring is applied in offset wells and with good knowledge of rock strength data.…”

“…Then any well can be re-drilled to see if a better set of operating conditions can be specified. In the same way, a new well can be "drilled" and its drilling performance optimized [8][9]. The matching is satisfied through the drilling time curve, when one compares actual drilling time curve versus the simulated one ( Figure 1).…”
