Gerard has over 45 years of experience in the Oil & Gas industry. During that time, he has worked exclusively in the well engineering domain. After being employed in 1974 by Shell, one of the major oil & gas producing operators, he worked as an apprentice on drilling rigs in the Netherlands. After a year he was sent for his first international assignment to the Sultanate of Oman. Out there he climbed up the career ladder from Assistant Driller, to Driller, to wellsite Petroleum Engineer and eventually on-site Drilling Supervisor, actively engaged in the drilling of development and exploration wells in almost every corner of this vast desert area. At that time, drilling techniques were fairly basic and safety was just a buzz word, but such a situation propels learning and the fruits of ‘doing-the-basics’ are still reaped today when standing in front of a class.
After some 7 years in the Middle East, a series of other international assignments followed in places like the UK, Indonesia, Turkey, Denmark, China, Malaysia, and Russia. Apart from on-site drilling supervisory jobs on various types of drilling rigs [such as helicopter rigs] and working environments [such as jungle and artic], Gerard was also assigned to research, to projects and to the company’s learning center. In research he was responsible for promoting directional drilling and surveying and advised on the first horizontal wells being drilled, in projects he had was responsible for a high pressure drilling campaign in Nigeria and in the learning center he looked after the development of new engineers joining the company after graduating from university. He was also involved in international well control certification and served as chairman for a period of 3 years. In the last years of his active career he worked again in China as a staff development manager, a position he nurtured, because he was able to pass on his knowledge to a vast number of new employees once again.
After retirement in 2015, Gerard delivered well engineering related courses in Australia, Indonesia, Brunei, Malaysia, China, South Korea, Thailand, India, Dubai, Qatar, Kuwait, The Netherlands, and the United States. The training he provides includes well control to obtain certification in drilling and well intervention, extended reach drilling, high pressure-high temperature drilling, stuck pipe prevention and a number of other ad-hoc courses. He thoroughly enjoys training and is keen to continue taking classes as an instructor for some time to come.
