Chartered Engineer Ivor R. Ellul attended the University of Malta for his bachelor of science in mechanical engineering. He studied at Imperial College, London, for his master of science and doctor of philosophy degrees in petroleum engineering. As the managing director of CiSK Ventures, Ltd., Ivor Ellul offers consulting services to the oil and gas industry. The oil and gas industry consists of companies divided into upstream, midstream, and downstream sectors. In the upstream category are corporations that discover and extract hydrocarbons. They're otherwise known as exploration and production companies. Comparatively, the midstream sector connects the upstream and midstream enterprises and involves storage and transportation activities. Then there is the downstream sector, which is an essential facet of the oil and gas industry. It's responsible for post-production operations in the industry, such as refining, distributing, and selling natural gas and oil-based products like lubricants and waxes. Organizations in the downstream sectors typically have the closest access to consumers. This sector is a key provider to numerous industries like, for example, the medical industry, delivering the ingredients for the manufacture of medical and pharmaceutical equipment. In particular, the downstream industry generates plastics, which are essential materials for manufacturing and packaging purposes. Agriculture is another field that benefits from the energy industry’s downstream sector. Natural gas is a fundamental requirement for fertilizer production generated by the downstream industry. Additionally, the oil industry helps develop pesticides, while farm equipment typically operates using diesel and gasoline fuel produced by the downstream sector.
