Abstract

Batuwangi is field that positioned ini the Sumatera at southeastern part. Batuwangi is in the development stage. The ENN-1 is one of well at Batuwangi field, placed at the geographical coordinates 5˚25'21.24063 South Latitude and 106˚18'55.73957 East Longitude. ENN-1 is drilled as a directional well spud on December 9, 2014 and completed on February 6, 2015. ENN-1 well has a TD (total depth) of 3804 ftMD and 3247 SSTVD, as an oil producer. In this paper, it will be studied the planning of casing utilized in the ENN-1 well, to see whether the desain of casing is already the most technically choice or not, to do calibration evaluation the grade casing used in ENN- 1 Well. To perform evaluation, the Maximum Load method will be used, the case will be choosen against desain factors of burst, collapse, and tension load resistant of casing. Based on the evaluation of the study, it is found that casing grade in the ENN-1 Well is exceeds the technical requirement. That fact, need to be corrected since it will lead to cost inefficient, it will much more expensive, since the casing purchased is higher than technical requirement. Therefore, in this studied offer the casing grade proposal to be utilized in the ENN-1 well which meet with technical requirement as well as economically much more efficient than current design.

Abstract

This research is driven by global pressures on sustainability and the urgent need for clean energy transitions in the industrial sector, particularly in energy, during the Industry 4.0 era. Digital transformation and green marketing strategies are vital to improving operational efficiency, fostering environmentally friendly innovations, and building sustainable competitive advantage. This study aims to examine the influence of Green Marketing Orientation, Green Innovation, and Digital Marketing on Sustainable Competitive Advantage in energy sector companies in Indonesia within the decarbonization context. A quantitative approach was applied using a survey method and Structural Equation Modeling–Partial Least Squares (SEM-PLS) analysis on 50 managerial respondents from companies with environmental policies, decarbonization initiatives, and digital marketing platforms. Findings show that Green Marketing Orientation significantly and positively affects Green Innovation, Green Innovation significantly enhances Sustainable Competitive Advantage, and Digital Marketing has the strongest effect on competitive advantage, whereas the direct influence of Green Marketing on competitive advantage is not significant. The study concludes that integrating green strategy, innovation, and digital capabilities is essential to achieving sustainable competitive advantage, offering theoretical contributions to Resource-Based View and dynamic capabilities frameworks and practical implications for strategic corporate management in the decarbonization era.
