Abstract
This paper examines the application of MPD in the Haynesville Shale basin for geothermal well construction, particularly focusing on Enhanced Geothermal Systems and Advanced Geothermal Systems. These geothermal targets present unique drilling challenges, which the study addresses through the use of MPD techniques to minimize non-productive time and reduce overall drilling and completion costs. A case study approach is employed, drawing on offset data from oil and gas operations as a baseline to assess the comparative benefits of SBP MPD. The methodology involves modeling drilling performance and well construction costs, followed by a comparative analysis against a well design without MPD.
Findings indicate that SBP MPD substantially enhances drilling performance by managing wellbore stability, kicks, and temperature-induced ballooning, thereby reducing NPT. It also provides cost-effective safeguards in production zones, mitigating risks such as formation losses, well control issues. Moreover, integrating MPD during the planning phase optimizes well design and improves overall HSE outcomes by reducing the likelihood of differential sticking and lost circulation. Collectively, these results highlight SBP MPD as a valuable approach to enhancing both operational efficiency and economic viability in geothermal drilling within the Haynesville Shale basin.
