The Trade-offs in Drilling the ‘Perfect’ Horizontal Well
Instructor: K.C. Oren, Horizontal Solutions Intl (HSI), Frisco, CO
The Instructor - Biography
KC Oren has BA’s in both Chemistry (1979) and Mathematics (1980) from Michigan State University. For the first third of his career, he worked in R&D and technical services for emerging drilling systems including MWD, LWD, mud motors (PDM) and steerable drilling systems, drill bits, with Eastman Whipstock, Smith International, TELECO and Halliburton.
The second third of his career was in software for drilling engineering and optimization, production reporting and economics, and geosciences. He held key positions as managing director, international business development, and in software development and product management.
Now in the final phase of Oren’s career he has the opportunity to draw on over 30 years of experience in both drilling and the geosciences to promote teamwork for achieving common goals for successful oil and gas exploration and production decisions for optimized results.
Who Should Attend
This introductory course is for anyone that wants to gain insight into both the geological and drilling aspects of horizontal well placement and control. Both geoscientists and engineers can benefit by attending this course to learn about and better understanding these two disciplines and the trade-offs of both as they impact the other for effective decision support in horizontal well objectives.
By the end of this course, participants will have an understanding of:
- Best practices for avoiding problems in drilling horizontal wells
- The various drivers by department/discipline and the trade-offs in achieving common goals and working together as an asset team
- Geo-navigation techniques using TSP (True Stratigraphic Position) modeling
- Four key principles in geo-navigation
- Leveraging all of your data for sound geosteering decision support
- Every horizontal well project requires varying degrees of drilling monitoring and support
- Horizontal well targeting techniques and recommended best practices
- Overcoming subsurface position uncertainty and how it impacts your geosteering decisions
- Horizontal drilling systems and high dog-leg severity BHAs
The personalities of engineers and geoscientists are often very different. And when it comes to corporate risk-reward assessment, company incentives for these individuals are often counter to the overall corporate end goals: higher IP and superior well performance among its peer group. For example, drilling team metrics and operations team’s objectives are often in competition to maintaining geological target objectives (staying in zone) and, as a consequence, not achieving maximum overall production results (highest possible EUR). Divergent drivers such as these common examples may create even greater dichotomies between individuals due to personality differences, incentives and personal motivation, and other competing corporate goals, and therefore often create conflict between otherwise closely aligned asset team members.
The course will explore the trade-offs of staying in the targeted zone (sweet spot) by carefully steering the well and monitoring every move along the way versus drilling ahead for maximum ROP (rate-of-penetration) and less NPT (non-productive time). We will introduce basic geo-navigation principals to be used for effective geosteering decision support.
An overall goal of the course is to provide a basis for better understanding what makes the drilling team itchy and uncomfortable versus the overall benefits of staying in zone … sometimes the extra deliberations or seemly costly modifications in a drilling plan do in fact pay big dividends … or do they? What both engineers and geologists need to know!
