This paper intends to present different models for optimal management of the extraction process in an oil drilling and extraction unit. In the beginning, the article deals with models related to under-balanced drilling to demonstrate that applying such methods is instrumental in increasing productivity by reducing the oil well formation damage, as well as helping to improve well performance. The article then analyses both hydrogeological wells productive capacity and estimation of oil deposit reserves through the production decline method. While characterizing the rate of decrease in production of an oil deposit, the declining oil production term is introduced, defined as both the actual decline and the nominal decline. To estimate the production of crude oil from deposits, analytical models have been developed corresponding to different geometric configurations. Some models consider oil as an incompressible fluid, while others (more complex) take account of its compressibility; this is corroborated with the modeling of stationary (independent of time) and nonstationary motions. In the end, the paper discusses that a model for optimal management of the extraction process implies determining an extraction policy that dynamically matches the extraction possibilities to beneficiaries' needs while maximizing/minimizing a performance objective function.
