Collision Avoidance and Well Interceptions – “Hits and Misses”

6 – 8 November 2013

Denver, Colorado | The Brown Palace Hotel & Spa

About this Workshop


The discipline of wellbore positioning in the oil and gas industry was born as a way to manage corporate risk. While a portion of this risk is economic, the process risk of a wellbore collision and subsequent well-control event make wellbore positioning a safety-critical activity. Planning to ensure that unintended well collisions do not occur during drilling requires a sound management plan for wellbore positioning technologies and techniques.

The potential for well collisions, and the need for interceptions is rising due to:

  • Drilling more complex-shaped wells in increasingly dense fields, often with less experienced crews
  • Potentially catastrophic consequences from an uncontrolled well flow event that mandates competently intercepting a blowout well
  • Legislature that requires well abandonment often necessitates subsequent subsurface interception to complete the work

Well proximity control and well interceptions are also being used to develop new architecture for improved reservoir drainage such as system assisted gravity drainage (SAGD). In addition, understanding the full cycle of well-positioning activities with improved policies, planning, and data management reduces uncertainty of downhole locations, leading to improved reserve evaluations.

In this workshop, the knowledge and skills available in the industry to manage both well proximity and well interception will be communicated. Attendees will share and learn about current best practice related to planning, policies, data management, practical application, and technology. Sessions will include presentations, discussions, breakout groups with industry experts, and practical exercises, including the opportunity to “drill” a relief well on a simulator.

Workshop Guidelines

Workshops maximize the exchange of ideas among attendees and presenters through brief technical presentations followed by extended Q&A periods. Focused topics attract an informed audience eager to discuss issues critical to advancing both technology and best practices.

Many of the presentations are in the form of case studies, highlighting engineering achievements, and lessons learned. In order to stimulate frank discussion, no proceedings are published and members of the press are not invited to attend.


Proceedings from the workshop will not be published; therefore, formal papers and handouts are not requested of speakers or panel members. A URL containing released copies of the workshop presentations will be available to attendees following the workshop.


In remaining consistent with workshop objectives and SPE guidelines, commercialism in presentations will not be permitted.  Company logos should be used only to indicate the affiliation of the presenter(s).

Continuing Education Units (CEUs)

Attendees will receive 2.0 CEUs.

One CEU equals 10 contact hours of participation. CEUs will be awarded through SPE Professional Development for participation and completion of SPE workshop. A permanent record of a participant’s involvement and awarding of CEUs will be maintained by SPE.
