Dear Colleagues,

The ISCWSA ebook has recently been updated, the ISCWSA ebook training videos can be accessed using this link.



Please also check here for the first release of the new "Well Intercept and Ranging" ebook.


The Society of Petroleum Engineers, Wellbore Positioning Technical Section are proud to announce the SPE Live Webinar Event which was held in June 2017.

We will post details here on the upcoming ISCWSA webinars.


Past Webinar Event Title: Well Collision Avoidance
Presented by: Steve Sawaryn, Drilling Engineering Consultant



The SPE Wellbore Positioning Technical Section (WBPTS) has been working towards a standard well collision avoidance rule for a number of years. Work started by establishing a common nomenclature and management practices. The subject involves all aspects of the Technical Section’s remit, which has expanded over the years to address the evolving drilling practices and technologies.
In the last 40 years, the frequency of unintended well collisions has decreased steadily as a result of improved directional surveying instruments, the introduction of computer based tools and databases and rigorous application of all the associated management practices involved in the planning and drilling of the wells. Despite this trend, today the greater use of pad drilling, decreased surface spacing and the introduction of more complex well trajectories has decreased the inter-well spacing at all points in the well. Unless the situation is managed, this closer proximity between wells can lead to a greater risk of well collision. An added complexity is that what is reportable is not clear, and not all collisions are reported. This situation makes analysis difficult, but useful inferences can be made. The necessary management practices, based on the WPTS work, were outlined in the paper SPE 184730 together with a summary of 19 anonymous health, safety and environment (HSE) and non-HSE well collisions which illustrate why continued vigilance in this subject matter is essential. There are strong economic as well as HSE reasons for doing so.
The webinar will review the management practices and lessons to be learned from the collision events. The discussions will also touch on the proposed collision avoidance rule which is scheduled to be presented in greater detail in the paper SPE 187073 at the forthcoming SPE 2017 Annual Technical Conference and Exhibition in San-Antonio, Texas.
