It is therefore important to evaluate the probability of such an event in the well planning phase, and at critical stages during the drilling phase.  A commonly used approach is to analyze the collision probability between two points, one in each wellbore, that are determined from geometric criteria only. This procedure may ignore point pairs with higher collision probabilities, and thereby lead to over-optimistic conclusions. Typically, the results from such methods will be accurate only for simple wellbore geometries such as straight sections and for position uncertainties that are highly symmetrical with respect to the wellbores. More advanced methods that overcome such limitations are impractical for general application because of high conceptual or computational complexity. This paper proposes novel analytic methods that potentially may overcome these problems. Formulae are derived for two important situations: the direct hit and the unintentional crossing scenarios. In both cases, the spatial region of interest is divided into carefully designed segments, such that the collision probability can be accurately evaluated for each segment. The total collision probability is then found by summing the results over all segments. The main advantage of this approach is that it gives accurate results for arbitrary well geometries and uncertainty ellipsoid orientations. The algorithms can easily be integrated in existing software for wellbore anti-collision analysis. The paper shows examples of results, which all are in good agreement with control calculations. Compared to existing methods, the proposed methods are therefore believed to represent a significant improvement to quantitative collision probability analysis, for both the wellbore planning and the drilling phases.\n",null,"00:15:00"]

These shortcomings of standard surveying have been discussed extensively in literature, most notably in Stockhausen (2003).  A method is presented here for compensating for wellbore position errors using additional information from continuous measurements or from slide sheets. The wellbore position is optimized by adding a correction (similar to a SAG correction) to the inclination at each stationary survey station. The adjustment can be applied in realtime to keep the wellbore TVD on plan. The accuracy of this method was verified by comparing corrected 95 ft stationary surveys with continuous memory data from the MWD tool.",null,"00:30:00"]
