Surveying Responsibilities

Surveying Responsibilities: 1. Drilling manager: – anti-collision strategy is in place; – blow-out contingency plan is available to ensure that as soon as there is a potential or actual blow-out at any time during the life of a well, the planning of a relief well and the decision on its surface location can be made … Surveying Responsibilities

Surveying definitions

Definitions of various surveying terms: Survey A series of measurements made to determine the borehole trajectory. A survey comprises position (North, East and True Vertical Depth) and/or direction (along-hole depth, inclination and azimuth) from which position is calculated. Survey tool accuracy The potential of a survey tool to determine the actual borehole position. The borehole … Surveying definitions

Survey policy

The survey accuracy requirements are dictated by the following: 1. Targets The geological target should be as large as possible to minimize costs (directional drilling and surveying), considering the expected survey uncertainties. 2. Collision avoidance The survey accuracy is defined by the separation factor (SF): the ratio between the 3D centre to centre well distance … Survey policy
