ZJ2区块井筒综合治理效果的评价

ZJ2区为靖安油田侏罗系油藏的一个老区块,自1996年投产以来,随着开发的不断深入,综合含水不断上升,地层流体内由于存在CO_2、H_2S等腐蚀性介质;井筒状况日益复杂。2006年6月开始,对该区进行全面综合治理,采取倒加缓蚀剂、优化杆柱组合及整井更换等多种措施综合治理管杆的腐蚀、偏磨及疲劳等。经过近一年的治理,效果非常显著,井筒状况得到了明显改善。     

Connecting business models with service platform designs: Exploiting potential of scenario modeling

Heterogeneity of technical and business designs, complexity of business collaborations, diversity and fragmentation of business roles are just some of the consequences of service platform evolution that complicate their business analysis. Service-oriented business models are usually on a higher abstraction level than the underlying service platform designs. Business models require detailing prior to their financial analysis, in order to include a proper cost and revenue structure and a realistic risk picture in techno-economic analyses. Understanding well service platform business processes and scenarios is equally important for realistic modeling of service usage, delivery and provision. This work discusses a techno-business modeling approach for quantitative analysis of services and platforms (21, 20 and 19), which “reinterprets” the business models by service platforms’ technical and business entities, processes and scenarios. In such a way it describes the roles, responsibilities and incentives of collaborating business actors in service delivery and provision and uses them in business analyses and valuations. We explain the approach theoretically, illustrate its analytical potential and demonstrate its practical use on the proof-of-the-concept service platform.

Valuation of multi‐stage BOT projects involving dedicated asset investments: a sequential compound option approach

The valuation of multi‐stage build‐operate‐transfer projects is not a trivial task. It needs to deal with uncertain project values in future expansions and the possibility of expansions or abandonment in the presence of project risks. The valuation problem becomes more difficult when multi‐stage projects require upfront and intermediate dedicated asset investments for future expansions. Dedicated asset investments may or may not create project values, depending on whether future expansions could be justified and realized. A sequential compound option model is proposed to tackle these important valuation issues.
