Dans le monde de la production pétrolière et gazière, la **Complétion de Top-Set** s'impose comme une technique cruciale pour maximiser la récupération des hydrocarbures, en particulier dans les réservoirs non conventionnels. Cette méthode consiste à **poser et cimenter le tubage au-dessus de la zone productive, laissant la zone elle-même ouverte pour la production.** Cette approche unique offre une solution simplifiée et rentable pour exploiter le vaste potentiel des ressources non conventionnelles.
La Complétion de Top-Set trouve ses applications les plus réussies dans les réservoirs non conventionnels, en particulier ceux avec :
Cependant, il existe certaines limitations :
La Complétion de Top-Set offre une approche rationalisée et efficace pour exploiter le vaste potentiel des réservoirs non conventionnels. En minimisant le contact du tubage avec la zone productive, cette technique améliore la productivité, réduit les coûts et offre une flexibilité pour les interventions futures. Bien que certaines limitations existent, les avantages de cette méthode continuent de la faire un choix privilégié pour les opérateurs qui cherchent à déverrouiller les richesses cachées dans ces formations difficiles.
