This paper will discuss a new technology that installs perforated casing and sand control in a single trip. The system incorporates telescoping perforations containing sand control media into ordinary API casing, run into the hole on standard liner hanger equipment. Applications for this technology include both producers and injectors, particularly those needing zonal isolation.

The key aspects of this technology, particularly the sand control media, sealing wax/polymer, and flow-actuated landing collar, will be discussed in great detail. Critical laboratory testing will also be reviewed, as well as installation procedures and cost analysis.

Application

The information presented in this paper is applicable to production and injection wells in sand producing formations.

Results, observations and conclusions

  • A new completion technology has been developed that eliminates the need for perforating and for pumping sand control media.

  • A one-trip sand control completion method that has zonal isolation capability has been developed.

Significance of subject matter

New one-trip sand control completion technology offers a large potential for significant capital expenditure savings.
