We concentrate on the traditional model of capture from the Oort Cloud. We improve the method of calculation of captured comet populations by combining large numbers of accurate orbit calculations with Monte Carlo methods. As a first step in the development of a Monte Carlo code we calculate accurate probabilities for changes of orbit in a single planet-comet encounter. These will be later used to study the orbital evolution of the Oort Cloud comets when multiple encounters take place.
