Abstract Abandonment is considered to be the last stage in the oil gas field cycle. Oil and gas industries around the world are bounded by the necessity of creating an abandonment program which is technically sound, complied to the stringent HSE requirement and to be cost-effective. Abandonment strategies were always planned as early as during the field development plan. When there are no remaining opportunities left or no commercially viable hydrocarbon is present, the field need to be abandoned to save operating and maintenance cost. The cost associated on abandonment can often be paid to the host government periodically and can be cost recoverable once the field is ready to be abandoned. In Malaysia, some of the oil producing fields are now in the late life of production thus abandonment strategies are being studied comprehensively. The interest of this paper is to share the case study of one of a field that is in its late life of production and has wells and facilities that planned to be abandon soon. The abandonment in this field is challenging because it involves two countries, as this field is in the hydrocarbon structure that straddling two countries. Series of techno-commercial discussion were held between operators of these two countries to gain an integrated understanding of the opportunity, defining a successful outcome of the opportunity and creating an aligned plan to achieve successful abandonment campaign. Thus, this paper will discuss on technical aspects of creating a caprock model, the execution strategies of abandoning the wells and facilities and economic analysis to study whether a joint campaign between the operators from two countries yields significantly lower costs or otherwise.

Oil Field Development

A quantitative analysis of economic risk associated with large investments in offshore oil and gas field development and production is presented. The analysis is intended as a supporting tool in decision-making faced with uncertainty and risk, to study the effect of alternative decisions in an easy manner. The descriptors for the project assessment, such as the Internal Rate of Return (IRR) and Net Present Value (NPV) are applied. The study demonstrates first the impacts of early pilot production (EPP) prior to a main oil field development on the field economy of an oil field development and production installation. Furthermore, the result of cases which reflect relevant situations connected with cost overruns are presented, as well as derivation of rational decision criteria for termination/continuation of a project subjected to cost overruns. Finally, an oil field development project scheduling is demonstrated.

Hybrid Concept

“Vertical type” spool configuration is commonly adopted as riser base spool for deepwater field development. With increasing water depths and risers subject to harsher environments, the excessive lower riser assembly motions and slugging induced fatigue damage have emerged as the governing design criteria for deepwater riser base spool design. Conventional vertical spool has inherent shortcomings to handle such design conditions. A new “hybrid” concept is therefore proposed, which extends beyond the “traditional” spool concept by integrating both vertical and horizontal spools into a 3D configuration. It inherits the vertical spool’s strength on handling large spatial expansion and utilise the pipe-soil interaction to dampen the potential resonance caused by slug flow. Several prototypes have been examined and the hybrid spool expansion-mechanism is discussed together with an optimisation procedure proposed. An advanced FEA technique using both Abaqus/Flexcom has been employed as part of the hybrid spool development, which consists of rigorous 3D dynamic analysis, bespoke non-linear soil interaction model and utilising the global riser dynamic behaviour. An in-house spool automation tool is developed to optimise the iterative analyses required to obtain a satisfactory hybrid spool configuration. This paper described a successful case study in recent deepwater hybrid riser bundle (multibore hybrid riser) tower development project, where the need to accommodate large lower riser assembly motion and slugging fatigue damage are the two main design drivers. This presentation provides a creative insight into this innovative technology.
