Formation dip geo-steering method |
摘要 |
A method of drilling a subterranean well from a surface location. The method comprises estimating a target formation depth, estimating a target formation dip angle and calculating a target line that creates a top and bottom of the target formation that forms a first projection window. The method further includes drilling within the first projection window, transmitting information from the subterranean well and projecting a target deviation window. The method can further comprise ceasing the drilling of the well and performing a well survey so that well survey information is generated. The method can then include estimating a formation dip angle with the well survey information and rig surface equipment monitoring data, calculating a target line that creates a revised top and bottom of the target formation that forms a second projection window, and drilling within the second projection window. |

1. A method of drilling a subterranean well from a surface location comprising:
a. estimating a target formation depth; b. estimating a target formation dip angle; c. calculating a target line that creates a top and bottom of the target formation that forms a first projection window; d. drilling within the first projection window; e. transmitting information from the subterranean well; f. projecting a target deviation ceasing the drilling of the well; and g. performing a well survey so that well survey information is generated. |
