Taking the TW block in Oriente basin, Ecuador as an example, the paper introduced cluster platform economic assessment after trap geological risk analysis, and realized cluster optimization. The evaluation process is as follows. 1) Trap geological risk analysis and resource assessment (traditional six factors assessment). 2) Platform economic assessment:design N platforms (different traps in different platforms), do economic assessment of each trap within the same platform, including investment (e.g. well drilling, platform construction, road and pipeline construction, perforation, surface recovery etc.) and income, and get rid of the trap with profit smaller than 0, and re-evaluate each trap till all the traps' profits are larger than 0. 3) Platform and trap optimization:optimize platform according to total profit of all the traps, then sequence the trap by profit controlled by the optimized platform. 4) New round platform and trap optimization:get rid of the optimized traps and go to step 2) and 3) till all the platform with profit larger than 0 has been selected. The new method has been used in platform and trap optimization in TW block which shows good result in practice.
