The management of oil fields that present high gas content is challenging, mainly in cases where this represents a bottleneck for oil production due to gas platform constraints. One way to deal with this problem is with the use of ICVs (Interval Control Valves), which enables the production to be controlled by zones in the wells.

In this work, we propose a methodology using reactive control rules for producers and ICVs, with GOR as monitoring variable, to improve the economic performance of the field. We compare the management of the field in three ways: (a) well management by shutting down producers when they reach an uneconomic GOR limit, (b) the use of ICVs on-off type and (c) application of multi-position type ICVs. We extend the application of algorithm IDLHC (Iterative Discrete Latin Hypercube) for the optimization process in this context. This study is made in a synthetic simulation case (Lira1_2022) with characteristics of a Brazilian pre-salt carbonate field with karstic features, high CO₂ content and using WAG (Water-Alternate-Gas) injection as recovery mechanism.

The results demonstrated that the use of ICVs has a great potential to increase the performance of the field, both in economic and production indicators, when compared to well shut-in management. Both ICV on-off and multi-position types achieved similar results, with a slight advantage to the multi-position type ICVs. The improvement in the field's performance was mainly caused by the interference among zones and wells, in which the closure of less productive wells, or zones, reflected in improvements in other more productive wells.

具有高含气量的油田的管理具有挑战性，主要是在由于天然气平台的限制而使石油生产成为瓶颈的情况下。解决此问题的一种方法是使用ICV（间隔控制阀），它可以通过井中的区域来控制生产。

在这项工作中，我们提出了一种使用生产者和ICV的反应性控制规则的方法，以GOR作为监控变量，以提高油田的经济绩效。我们通过三种方式比较该领域的管理：（a）通过在生产商达到不经济的GOR限制时关闭生产商来进行井管理；（b）使用ICV开关型和（c）应用多位置型ICV 。在这种情况下，我们将算法IDLHC（迭代离散拉丁超立方体）的应用扩展到了优化过程。这项研究是在一个模拟模拟案例（Lira1_2022）中进行的，该案例具有巴西岩盐特征的岩溶前期碳酸盐岩田，具有较高的CO ₂含量，并使用WAG（水-交替气）注入作为采收机理。

结果表明，与封闭式管理相比，使用ICV具有很大的潜力，可提高经济和生产指标方面的绩效。ICV开关式和多位置型都取得了相似的结果，但与多位置型ICV相比，略有优势。油田性能的提高主要是由于区域和油井之间的干扰所致，其中产量较低的油井或地区的关闭反映在其他产量较高的油井的改善中。
