An integrated identification of hydrocarbon phases in offshore condensate gas reservoirs

During the early evaluation period of offshore oil gas fields,it is difficult to accurately identify complex hydrocarbon fluid phases in condensate gas reservoirs,due to lack of knowledge about the regional fluid property and distribution as well as nosystematic and incomplete testing and pressure measuring restricted by offshore difficult environments and high operation costs.Such testing results or a single data of conventional well logging will easily lead to wrong judgements or ambiguous interpretions,which may make correct evaluation and reserves calculation of special reservoirs difficult and have a great impact on designing development plans for the reservoirs.The researches and actual working have shown that a technical thinking of integrated identification,based on conventional data,can effectively solve the problem to identify hydrocarbon phases in an offshore condensate gas reservoir.
