Daftar Isi:
- Commodity demand and the production costs strongly affect the oil price. For the industry, market price is considered as uncontrollable, while production cost is controllable. PT. Diamond Energy Indonesia (PT.DEI), one of the largest oil producers in Indonesia, operates "Humaira" oil field with more than 2,000 oil/gas production wells also strives to improve its competitiveness. The subject of this study is the existence of oil wells having high wellhead elevation which occurred to approximately 6.7% from the population. This situation existed as result of surface erosion of the well site due to rainfall, but mainly due to the addition of wellhead component (retrofit) as low cost fixing to the failure of the existing wellhead design’s sealing capability. This extra elevation, however, creates difficulty for the workover rig because of limited clearance below the working platform for the installation of the required blowout preventer (BOP) stack specification. Several alternative solutions were brainstormed by involving the highly experienced in-house personnel via focused group discussions. Kepner-Tregoe decision analysis was selected to seek the most optimum alternative solution for a safe operation that meets compliance, cost effectiveness and practicality as the business objective. The expected business implication of this study is a tangible saving based P50 Cost of Poor-Quality scenario of $742,220.00.
