Construction of contingency estimation method for overseas oil and gas acquisition evaluation based on risk quantification

“…1) The contingency cost of oil and gas field surface engineering is generally estimated by the rate method based on a ratio of surface engineering construction investment. In the evaluation stage of overseas oil and gas acquisition projects, the contingency rate can be expressed by risk factors in terms of connotation [4] . The estimate of contingency can be expressed in Formula 1.…”

“…CRYSTAL BALL software was used for the simulation analysis. Calculation of unforeseeable fees for equipment materials is as follows: Pr = 0.1339Pr 1 + 0.1260Pr 2 + 0.2047Pr 3 + 0.3701Pr 4 + 0.1654Pr 5 (4) The results are shown in Fig. 1 and Fig.…”
