Reservoir connectivity has a considerable effect on reservoir characterization, plans for field developments and production forecasts. Reducing the uncertainties about the lateral and vertical extension of different pay zones is the main step in developing and managing the reservoirs. Nearly all the proposed methodologies for the verification of reservoir connectivity are limited to the study of the communication of different compartments in one field. In the presented paper, first a comprehensive procedure is proposed to study the reservoir connectivity between nearby fields. The steps in this procedure are not necessarily hierarchy, but all the considerations in each step are studied to cover all the uncertainties that affect the reservoir communication. This procedure mainly comprises the study of reservoir extension, pressure communication in the hydrocarbon column, fluid similarity, top seal efficiency and faults sealing. Then, to apply this procedure for proving the communication between nearby fields, a case study of Ilam Formation in southwest of Iran is presented. The results confirm the lateral connectivity of the three pre-explored distinctive oil fields in Ilam Formation. The established connectivity leads to an increase in the pre-estimated oil-in-place volumes. This incorporated case study demonstrates how different data including geophysics, structural and petroleum geology, production and reservoir engineering are integrated to prove the communication of Ilam reservoir between these fields. This manifested technique is a powerful road map for other cases worldwide and is extremely recommended to be performed before developing those fields that are suspicious to lateral connectivity.

相邻油田之间储层连通性研究的综合程序

储层连通性对储层表征，油田开发计划和产量预测有很大影响。减少不同产层横向和垂直延伸的不确定性是开发和管理油藏的主要步骤。几乎所有提出的用于验证储层连通性的方法都仅限于研究同一领域中不同舱室的连通性。在本文中，首先提出了一个综合程序来研究附近油田之间的储层连通性。该程序中的步骤不一定是分层的，但是对每个步骤中的所有考虑因素都进行了研究，以涵盖影响储层连通性的所有不确定性。该程序主要包括研究储层扩展，烃柱中的压力连通，流体相似性，顶部密封效率和断层密封。然后，为了应用该程序来证明邻近区域之间的通信，以伊朗西南部的Ilam组为例进行了研究。结果证实了Ilam组三个已勘探的独特油田的横向连通性。既定的连通性导致预先估计的现场采油量增加。该案例研究表明，如何整合包括地球物理学，结构和石油地质学，生产和油藏工程在内的不同数据，以证明这些地区之间的Ilam油藏通信。
