SPE Thailand Monthly Meeting - Jan 2020
Development of Organic Shales Outside North America by Hai Liu, Schlumberger
January 16, 2020  ·  The Landmark Hotel Bangkok

The success of organic shale development in North America has brought a great interest in organic shale exploitation internationally. The employed drilling and completion practices are based on the techniques that have been successful in organic shale developments in US, and hydraulic fracturing treatments are primarily dominated by slickwater owing to its low cost and benefit in maximizing the stimulated reservoir volume (SRV). However, the international shale plays are usually in high tectonic stress environment, complex geological structures, and frequently contain natural fractures, which are quite different from most of the plays in US with relatively simple structure and more relaxed stress environment. These complexities have resulted in additional challenges in both reservoir understanding and completions, and ultimately production performance. Proppant placement issues and casing deformation are commonly experienced in slickwater treatments in these tectonically active plays, and production results were below expectations in the early phase of the appraisal and development. Numerous studies have been performed and revealed the stress sensitivity in all the wells in which the fracture system starts to deteriorate when the effective stress reaches the critical value, resulting in many perforation clusters not contributing to production due to the loss of connectivity to the wellbore. This leads to an important conclusion that fracture conductivity is equally important as the SRV for high stress organic shale plays, and the treatment strategy shall be recalibrated from current slickwater treatments that do not provide sufficient fracture conductivity due to low proppant concentration as well as challenges of proppant placement. The presentation provides an overview of challenges in these organic shale plays with high tectonic stresses, and highlights a few important findings and practices that would address the problem and improve production performance.


Notice!

Since 2013, SPE Thailand has 100% subsidized Members attendance fees at our Monthly Meetings.   Owing to reduced sponsorship income (driven largely by lower E&P activities in recent years), we will be revising the monthly meeting fees for all categories commencing in September 2018. Note that the fees for Members will still be significantly subsidized, hence we would encourage all Non-Members to consider joining SPE.
