Abstract One of the critical tasks during the oil rim development is to control production wells to prevent water breakthroughs and gas outs. Key factors are control over drawdown and on-time choke restriction of the well in case of a gas out and an extreme gas factor increase.

Abstract This publication presents how an oil asset unlocked idle production after numerous production upsets and a gas hydrate blockage. It also uses economics to justify facilities enhancement projects for flow assurance. Field F is an offshore oil field with eight subsea wells tied back to a third party FPSO vessel. Field F was shut down for turnaround maintenance in 2015. After the field was brought back online, one of the production wells (F5) failed to flow. An evaluation of the reservoir, well, and facilities data suggested that there was a gas hydrate blockage in the subsea pipeline between the well head and the FPSO vessel. A subsea intervention vessel was then hired to execute a pipeline clean-out operation, which removed the gas hydrate, and restored F5 well oil production. To minimise oil production losses due to flow assurance issues, the asset team evaluated the viability of installing a test pipeline and a second methanol umbilical as facilities enhancement projects. The pipeline clean-out operation delivered 5400 barrels of oil per day production to the asset. The feasibility study suggested that installing a second methanol umbilical and a test pipeline are economically attractive. It is recommended that the new methanol umbilical is installed to guarantee oil flow from F5 and future infill production wells. The test pipeline can be used to clean up new wells, to induce low pressure wells, and for well testing, well sampling, water salinity evaluation, tracer evaluation, and production optimisation. This paper presents production upset diagnosis and remediation steps actioned in a producing oil field, and aids the justification of methanol umbilical capacity upgrade and test pipeline installations as facilities enhancement projects. It also indicates that gas hydrate blockage can be prevented by providing adequate methanol umbilical capacity for timely dosing of oil production wells.

Aiming at the southern areas of Bohai glutenite reservoir natural capacity is low, without obvious interlayer, filter lost badly, cause conventional hydraulic facturing in short of effect on increasing production, the paper conducted the research and application of technology on Y104-6 well. According to the reservoir geological characteristics and well conditions, the paper studied on fracturing scale determination, the perforating section, and the optimization of fracturing material selection, and application. Completed the injection into well fluid amount 1491.9 m3, proppant 188 m3, displacement of pump 7.5 m3/min. After treatment, average fluid flowing production achieved 18.6 t/d, average daily oil production 6.8 t, stimulate effect and the economic benefit is remarkable. This well fracturing technology, make the successful application of the southern areas of Bohai glutenite reservoir a significant breakthrough, recoverable reserves get promoted for big thick section glutenite reservoir development and vertical fracturing of the organization and implementation has provided valuable experience.
