Major Projects
In recent years, MacKenzie has evaluated a large number of properties in the Middle East, especially in the Kurdistan region of Iraq. Some of the Kurdistan properties evaluated have required careful analysis of the structure in order to define reservoir limits and structural closure. Some structures with 2–D seismic data, sparse well control, and inconclusive tests required extensive interpretation of the lateral, updip, and downdip limits of the accumulation. He also has extensive experience in the North Sea, North Africa, West Africa, and Europe including Austria and Romania.

Many of MacKenzie’s African evaluations include the onshore and offshore properties in Egypt, Nigeria, and the Republic of Congo. In recent years, the Congo properties evaluated were related to continental breakup in the Jurassic. MacKenzie has evaluated dozens of properties in Nigeria since 1994, ranging from heavy oil in the northern oil-producing area, the stacked reservoir structures near the coast, and some of the largest structures developed in offshore Nigeria to date. In Egypt, he has evaluated major properties associated with LNG production.

Many of the fields worked by MacKenzie in Europe have been in Italy and the North Sea. In Sicily, MacKenzie resolved lithologic, fluid, and structural issues in two producing fields. In the North Sea, MacKenzie has used 2–D mapping in Petrel to generate structure and isopach maps.
