INJECTION WELL AND METHOD FOR DRILLING AND COMPLETION

摘要

Disclosed is a method and apparatus for completing an injection well, wherein the horizontally-extending portion of the well is drilled in a wave pattern. Injection and hydrocarbon recovery sections or alternatively spaced along the horizontally-extending portion and are isolated from each other by packers in the wellbore. The injection and hydrocarbon recovery sections are positioned at the opposed peaks of the wave pattern.

主权项

1. A method of completing an injection well to produce fluid hydrocarbons from a subterranean hydrocarbon bearing formation, comprising the steps of:
drilling a well with a horizontally-extending portion that extends in a wave form pattern that has spaced-apart opposed peaks; installing a tubing string in the horizontally-extending portion with the tubing string extending from the well surface; injecting fluids into the wellbore at one set of peaks of the wellbore waveform; installing packers around the tubing string to seal off the annular space between tubing string the wellbore; and flowing hydrocarbons into the tubing string at the opposite set of peaks of the wellbore waveform.
