MANAGING OUR FOOTPRINT In 2016, Hess Corporation joined Kosmos and Chevron as a partner in Block 42. The agreement with Hess is consistent with Kosmos’ business strategy of retaining operatorship through exploration and collaborating with industry-leading partners who bring technical and regional expertise, as well as strong financial capabilities. Hess joins our existing partner, Chevron, in Suriname. Kosmos conducted our third seismic campaign offshore Suriname in late 2016, acquiring over 6,500 square kilometers of additional seismic data over Blocks 42 and 45. Because the area offshore Suriname has very strong sea currents, we spent additional time and resources developing an understanding of the region’s physical characteristics and their potential impact on operational safety before conducting the seismic survey. If not properly monitored and incorporated into survey plans, ocean currents can disrupt seismic operations in a number of negative ways, such as equipment damage due to extreme force on streamer cables and winches, 42 Kosmos holds exploration licenses offshore Suriname for Blocks 42 and 45. Suriname represents a top-ranked opportunity in Kosmos’ exploration portfolio and we continue to mature significant prospects offshore for drilling. Additionally, over the past four years, we have built relationships with stakeholders, listened to community members, developed local employees, and implemented various social and environmental projects.
