Sažetak
The calculation of hydrocarbon reservoir volume using solid is numerical integration problem. It is solved by numerical integration of function f(x), i.e. integrand, continuous in interval a<=x<=b. It includes approximation of f(x) with polynomial functions, like trapezoidal of Simpson formulas. Smaller calculation error can be reached by using Simpson rule based onto Lagrange polynomial. These two rules are regularly used for reservoir volume calculation, where trap anticline is approximated by frustum right circular cone. The error can be decreased with lowering equidistance between integrated areas.
