This joint industry project (JIP) will establish a set of Best Practices for SAGD well construction covering the field activities that can impact casing and liner/screen integrity.  The objective is to assess the impact and effectiveness of the many different activities, procedures and equipment involved during SAGD well construction in an effort to help ensure that completed well installations actually meet the design intent.  First, a comprehensive assessment of the current practices and thinking of a number of operators and service companies involved in SAGD well construction will

Status: Commenced November 2002 - The objective of this JIP is to investigate the technical and economic feasibility of several alternative SAGD well configurations and completion designs. This will be done on a comparative basis against selected performance attributes and economic benchmarks that will be established for conventional SAGD well developments.
 

Status: Commenced in 2002 - This JIP involves evaluation of the potential impact of thaw caused by drilling and production operations on the design and operation of production wells installed through permafrost.

The work scope of the project includes a seminar on the design and implementation of producing wells in arctic permafrost regions to address potential thaw subsidence impacts, a review of existing records to characterize the permafrost interval in the development areas, and engineering evaluation of well design alternatives.

Status: Phase I - launched Q1, 2005 - The reliability of a sand control completion is influenced by factors such as reservoir conditions, well configuration and operating practices. To date, little information has been available on how these and other factors influence the service life.

Status: Completed - In March 1999, C-FER launched an investigation into the causes of casing and slotted liner failures in heavy oil operations. Operators reported failures in primary, cyclic steam and Steam Assisted Gravity Drainage (SAGD) wells. A series of multi-sensor caliper logs were run in a number of deformed wellbores to characterize the deformations.
