The discovery rate for the giant fields peaked in the late 60s and early 70s and declined remarkably in the last two decades. About thirty giant fields comprise half of the world oil reserves and most of them are categorized as mature field.The development of those fields entails new and economically viable techniques, and proper reservoir management strategies.Mature field development is a broad subject.It can, however, be divided into two main parts:Well development, andreservoir development.Depending on the field type, history, and prospects, the development plans could be done on either one or both.This paper covers reservoir engineering aspects of mature field development.Determination of the amount and location of the remaining oil is the key issue in this exercise.Techniques to improve the recovery factor such as tertiary recovery, infills, horizontals, and optimal placement of the new wells are the other elements of reservoir development.Definition and elements of mature field developmentOil fields after a certain production period are called mature field.A more specific definition of mature fields is the fields reached the peak of their production or producing fields in declining mode.A third definition could be the fields reached their economic limit after primary and secondary recovery efforts.Fig. 1 shows a typical production life of a field.Any points indicated by a question mark can be considered as the time when the maturity is reached.The tendency, however, is to define the decline period indicated by the arrow in Fig. 1, which is typically reached after having some secondary recovery efforts.Increasing water and gas production, decreasing pressure, and aging equipment are other indicators of maturity.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
