Abstract
The paper describes a method of computer-aided generation of project horizontal wells realized by the in-house Epsilon program package.
For each development target, the horizontal wells are placed downwards, once the “drilling carpet” has been generated. Conventionally, as a horizontal wellbore trajectory, a segment connecting a couple of points representing positions of the previously generated project vertical wells is taken. The horizontal wells’ generation method includes the following stages:
- generation of the project horizontal wells considering the trajectory acceptability,
- checking of well candidates to ensure they meet geological criteria,
- analysis of economic performance and comparison with the only-vertical-wells drilling scenario,
- checking of advisability of placement of horizontal wells in zones where vertical wells alone do not make economic sense.
Based on a field’s proxy models, the Epsilon generates a “drilling carpet”, that is, a stage-wise placement of project wells by an irregular maximum-density drilling pattern that satisfies the geological, operational, and economical restrictions.
The aim of the study was to develop methods and algorithms to place automatically horizontal wells in all Company’s assets that to-date include 240 productive formations of 85 fields.
