Introduction

Computer-based modeling is used in the oil industry for a wide variety of problems. Exploration efforts require that an area be thoroughly understood before picking a prospect location. The integration of information both in the spatial realm and the time realm is critical in identifying the most probable location of generation, diffusion, migration, and trapping of hydrocarbons. It is not an easy task to create a quantitative analysis of an entire region with limited data. It can be difficult also if there is a large amount of information to envision the integration of all the data.

The 123D Simulation and Visualization Technology is an interdisciplinary response to the demand for innovative approaches which will substantially increase hydrocarbon predictability and improve exploration prospect development for both prospecting and drilling. It's a knowledge tool intended to lower regional exploration prospect risk and to quantify the reserves of individual drilling prospects.

The industry used 1D and 2D basin modeling for several decades, but the need for 3D modeling was recognized in the mid 90's (Meshri, 1996). Today all the majors are using 3D basin modeling including multi-component flow simulation of oil, gas, and brine.

The modeling of subsurface pressure and temperature can also supplement other quantitative techniques used in oil exploration. The application of basin modeling, which is integrated with problems involving diagenesis is described by Meshri (1990). Fluid inclusion studies and prediction of paleo oil-water contacts are also subjects, which form a symbiont relationship with hydrocarbon systems modeling.
