Duration

5 Days

Discipline

DRILLING

Introduction

The 5 day session on Stuck Pipe & Fishing in HPHT wells focuses upon the key mechanisms with which pipe becomes stuck and how the sticking mechanisms can be prevented through proper planning and operational procedures. It also covers the Driller’s First Actions, i.e. what the Driller should do as soon as he has become stuck in order to maximise the possibility of becoming free.

To maximise learning, delegates work through actual Stuck Pipe case histories, identifying the sticking mechanisms, prevention measures and what to do to get free. Presentation material is through the use of PowerPoint, case histories and video.

Typically, Fishing is the last chance for the Operator to recover the stuck BHA / fish from the hole. In many cases work pressure is considerable, since fishing is a high cost operation and because Governments often demand that nuclear sources for example are recovered. Thus, it is vital that Fishing is a success. And yet there is an estimated 85% failure rate.

The session on Fishing focuses upon how it can be a success first time. To maximise learning, delegates work through actual fishing case histories and follow proven procedures and methodologies. Presentation material is through the use of PowerPoint, case histories and videos may seem simple enough in theory, but not all employees have the necessary skills and competencies to successfully apply it in practice. One of the key components in driving change is employee training and development. Provide additional risk management training to the in-house risk management team and business units. Risk managers may conduct it personally or outsource to third party providers. In-depth risk management training should include (this example is based on the actual risk management Training course is intended to introduce the fundamentals of Risk Management being a systematic core built-in function in all types of organizations.This training course provides you with a general overview of all main aspects of Risk Management starting from the definition of the term and going through the building blocks of the total integrated Enterprise Risk Management model (ERM) together with its related Risk Governance arrangements.

This training course will enable participants to appreciate the need and urgency to re-visit their existing Risk Management framework with an aim to improve and align with the overall organization strategic plan.

Methodology

The training course will be highly participatory and the course leader will present, guide and facilitate learning, using a range of methods including formal presentation, discussions, sector-specific case studies and exercises. Above all, the course leader will make extensive use of real-life case examples in which he has been personally involved. You will also be encouraged to raise your own questions and to share in the development of the right answers using your own analysis and experiences. Tests of multiple-choice type will be made available on daily basis to examine the effectiveness of delivering the course.
