Abstract
Examples described herein provide for evaluating greenhouse gas emissions for a fluid for a hydrocarbon exploration and recovery operation. The method includes performing an emissions lifecycle analysis for the drilling and completion fluid. The method further includes determining a greenhouse gas emissions value for the drilling and completion fluid based at least in part on a result of the emissions lifecycle analysis. The method further includes modifying a portion of the hydrocarbon exploration and recovery operation based at least in part on the greenhouse gas emissions value.
