摘要： A novel method is presented to automatically design a multi-well development plan given a set of previously interpreted subsurface targets. This method identifies the optimal plan by minimizing the total cost as a function of existing and required new platforms, the number of wells, and the drilling cost of each of the wells. The cost of each well is a function of the well path and the overall complexity of the well

摘要： A hybrid evolutionary algorithm (“HEA”) technique is described for automatically calculating well and drainage locations in a field. The technique includes planning a set of wells on a static reservoir model using an automated well planner tool that designs realistic wells that satisfy drilling and construction constraints. A subset of these locations is then selected based on dynamic flow simulation using a cost function that maximizes recovery or economic benefit. In particular, a large population of candidate targets, drain holes and trajectories is initially created using fast calculation analysis tools of cost and value, and as the workflow proceeds, the population size is reduced in each successive operation, thereby facilitating use of increasingly sophisticated calculation analysis tools for economic valuation of the reservoir while reducing overall time required to obtain the result. In the final operation, only a small number of full reservoir simulations are required for the most promising FDPs.
摘要翻译：描述了一种混合进化算法（“HEA”）技术，用于自动计算场和排水位置。该技术包括使用自动化井计划工具在静态储层模型上规划一组井，以设计满足钻井和施工约束的现实井。然后基于使用最大化恢复或经济效益的成本函数的动态流模拟来选择这些位置的子集。特别是，使用成本和价值的快速计算分析工具最初创建了大量候选目标，排水孔和轨迹，随着工作流程的进行，每个连续操作中的人口规模减小，从而便于使用越来越复杂的计算水库经济评估的分析工具，同时减少获得结果所需的总体时间。在最后的操作中，最有希望的FDP需要少量的全油藏模拟。
