Formation oil high pressure property parameters are essential to the reserve estimation and development plan compilation of oil fields. Due to the high cost and safety concerns of offshore oilfields, only a small amount of PVT samples can be obtained from exploration wells and appraisal wells, in some cases, there will be no samples or samples cannot present the actual conditions like degas. To solve the difficulty of obtaining high pressure property parameters during the appraisal stage of offshore oilfields, this article raised a new analogy method: high pressure property relationship chart. The existing high pressure property data can be regressed to a regional chart, and the chart can be utilized to predict high pressure property parameters. This method can realized the idea that formation oil high pressure property parameters can be predicted by surface oil samples or MDT density. Exploration practices in Beibuwan Basin show that this method can predict high pressure property parameters of formation oil well.
