Well control: drill-through equipment course.

Overview

The Drill-through equipment course (DTE) offers the best introduction to well control equipment available for people newly joining the drilling industry and starting out on floating drilling rigs with subsea stacks.

This five-day International Association of Drilling Contractors (IADC) accredited course will assist new rig and office staff working with drilling operations in understanding drill-through equipment installed on rigs utilizing subsea stacks, both from a theoretical as well as a practical perspective. Basic engineering, design, operation and maintenance principles are reviewed and illustrated. Hydraulically-piloted control systems are thoroughly explained, and the basics of multiplex control systems are discussed.

Over the past decade, this information has proven to be invaluable to new crew members on the rig as well as to DSVs (drilling supervisors) transferring to floating rigs. Office managers will also greatly benefit from this course as they will increase their basic understanding of the well control equipment used by their staff.

You will learn

Attendees will learn about the logic of the equipment and systems which are used to provide well control safety on floating drilling rigs. All major manufacturers are discussed. The focus is on practical information that can be put to immediate use, directly benefiting your drilling operation with lower downtime and increased reliability.

Based on the knowledge gained from over 4,000 rig surveys, this seminar looks at each piece of equipment and discusses:

  1. The standard process of drilling a well

  2. How drill-through equipment works - using cross sections and animations to illustrate

  3. The various items of drill-through equipment provided by the major OEMs (original equipment manufacturers)

  4. Proper maintenance routines - what to look for, why equipment is designed in a specific manner, what doesn't work or did not work in the past, and how we improve our equipment and maintenance procedures

  5. Unexpected failures and lessons learned

Specific equipment failure case studies are discussed with solutions provided. 

The DTE is led by experienced trainers, all of whom are former subsea supervisors as well as drill-through equipment surveyors. All trainers have undergone didactical training to enhance their teaching skills. Classroom delivery includes a comprehensive syllabus, supported by modern PowerPoint presentations, computer animations and videos. During this 5-day course ample time is allowed for discussion, both with the instructor as well as amongst candidates themselves.

Your future development

Upon successful completion of the DTE course, candidates receive a certificate of completion which is accredited by the IADC. This certificate is valid for five years.

The DTE is part of our multi-level educational curriculum. Candidates who have successfully completed this training course and would like to extend their knowledge might also be interested in attending additional well control equipment course. We offer the intermediate level Well Control Equipment Course (WCEC) or the advanced level Deepwater Challenges Course (DWC). In order to be able to attend the DWC, candidates must have successfully completed the WCEC or at minimum the DTE.

Suitable for

Those who will be involved with floating drilling operations and equipment as a user, manager or member of a regulatory body. This seminar has been called the best introduction to well control equipment available for people working on floating drilling rigs with subsea stacks.

Prerequisite courses

Field and/or equipment experience would be helpful, but is not necessary. The DTE course is not developed for experienced floating rig personnel. Experienced rig workers and DSVs can attend our intermediate level Well Control Equipment Course for Floaters (WCEC), for which basic well control equipment knowledge is required.
