Drilling Operations_Look Inside: Often drilling programs have documented risks and mitigations against the identified risks. Although preventative actions against the identified risks may be expressed within the program, the emphasis is usually on the mitigation barriers against the risks hence it is not uncommon to see the term “risks and mitigations” in a drilling program. This book was born out of the desire to deliver the same risk management concept applied in chemical plants and refineries into drilling planning and operations. Barriers to risk events should include preventative barriers and mitigation barriers. Mitigation barriers are reactive- wells operations safety and cost can be improved by creating preventative barriers to reduce the chance of the risk event occurring and also with mitigation barriers to improve the recovery time if a risk event should occur.
Details of the Chapters:
This book provides useful insight to drilling operations improvements in the area of cost and risks. This book focuses on improving drilling operations by managing barriers (both preventative and mitigation) barriers to risk events. In Chapter 1, the basic principles of risk management are described from identification of risks to creating barriers (people, process/procedures and equipment) for identified risks as well as steps to help barrier creation. Chapter 2 describes the process of drilling optimization: reviewing non productive events from offset wells or other drilling campaign, categorizing non-productive time events into those that increase “drilling time” and those extend “flat time” and barriers to be put in place to optimize drilling operations. Chapters 3 to 13 focus on common non-productive time events for example loss circulation, well control etc. that lead to down-time in drilling operations and barriers to the risk events as well as monitoring/control barrier. Useful drilling calculations are highlighted in Chapter 14. Chapter 15 focuses on other continuous improvement opportunities.
