EconomicsPSCs are negotiated separately. Royalties to the KRG are different with each contract.
VST has negotiated a 15% royalty, NKO for the same development only 10%, therefore NKO is the better investment.
Unfortunately, LFD has negotiated a 40% royalty. Along with their 40% working interest, the numbers are difficult to crunch. Any prospect generally is reduced by about 80%. Pumpers don't tell you that.
