Introduction
As part of the revisit of my previous evaluation of publicized modelled calculations of Guyana Government Take ratios, I had observed last week that, just over two years ago [August 2020] the Inter-American Development Bank, IADB, and also much more recently, in August of this year, 2022, Rystad Energy, published modelled calculations of Guyana Government Take along with projections of Guyana Government revenue flows and related operational and investment matters, over a decade and more going forward to 2025-7 and beyond into the 2030s. These results are quite revealing, given that the modelling is based on widely publicized targets set by ExxonMobil and its partners going forward for the Stabroek Block to 2025-2027, and indeed beyond that.
