1 XMAS TREES AND WELL HEADS, OPERATION AND TESTING INSTRUCTOR: ANTONIO ABREU 9 12 JULY 2018 Jakarta Why Choose this Training Course? Xmas Trees and Well Heads are critical parts of any Oil & Gas Well. They control the pressures in the Casings and Production Tubing, regulate the production rates and are a vey important barriers in case of leaks This training course will highlight: All components of a Well Head and of a Xmas Tree and installation sequence Investigation, mitigation and cure of SAP Pressures Casing and Tubing Seals (monitoring and leak repairs) Different Causes of SAP Pressures. Hazards originated by faulty wellheads (and their mitigation). What are the Goals? The main goals of this course is to revisit the importance of Well Heads and Xmas Trees and analyze all the problems that may affect well head and Xmas Trees integrity and well integrity as a whole. To understand how critical are good Cementations to avoid future well Heads and well Integrity Problems. To understand SAP Pressures, their origin and their impact on Safety and Well Life Cycle is also a major focus of this course. By the end of this training course, participants will learn to: Develop the knowledge relationship between surface (Well Heads) and downhole. Investigate leaks and identify cause of leak Determine Tubing pressures (based on depth of perfs, density of fluid and BHFP). Investigate SAP pressures based on well pressure monitoring using 2 and 3 pen recorders. Explain influence of corrosion models on MAASP pressures and on Well Life Cycle.

2 How will this Training Course be Presented? Course will be presented using properly designed slides, some with animation and several videos on relevant issues. A printed manual containing all the slides and/or electronic from in PDF will be delivered to each attendant. Teaching methods include also calculations on related issues. Who is this Training Course for?. This training course is suitable to a wide range of professionals but will greatly benefit: Field Services Foremen Operations Foremen Petroleum Engineers Production Engineers Drilling Engineers Completion Engineers Oil Field Technical Staff Course Agenda Day One: Introduction : Well Heads and Xmas Trees Operational Safety Reservoirs, wells and well heads Problems caused by poor cement jobs Well construction and primary cement jobs Construction of a well from Casings to Well Head.
