Petro-Canada is a retail and wholesale marketing brand of Suncor Energy. Until 2009, it was a crown corporation of Canada , headquartered at the Petro-Canada Centre in Calgary, Alberta. In August 2009, Petro-Canada merged with Suncor Energy, with Suncor shareholders receiving approximately 60 percent ownership of the combined company and Petro-Canada shareholders receiving approximately 40 percent. The company retained the Suncor Energy name for the merged corporation and its upstream operations. It continues to use the Petro-Canada brand nationwide, except in Newfoundland and Labrador, for downstream retail operations. Wikipedia.

A simulation study was conducted to examine the effects of changing the landing position of the short production-tubing string relative to the heel of a steam-assisted gravity-drainage (SAGD) production well. A homogeneous discretized wellbore model with the riser section was used in this study. Generally, a reservoir is modeled independently of the wellbore. However, this study models the reservoir and wellbore simultaneously in order to understand their interactions. SAGD performance is affected by many interrelated parameters; however, this paper is focused only on the effects of changing the short production-tubing string relative to the heel of the well. This paper outlines two independent case studies: 1. The first study involves shortening the short production-tubing string relative to the heel of the well. It was found that as the short tubing string was pulled back from the heel of the well, the bitumen-production rate decreased, and the amount of steam produced through the short production-tubing string increased. 2. The second case study outlines the impact of extending the short production-tubing string past the heel of the well on bitumen production and steam/oil ratio (SOR). From this case study, it was found that as the short production-tubing string was pushed past the heel of the well, the bitumen-production rate stayed the same, but the steam-injection rate decreased, which consequently decreased the SOR. It was also observed that a lower pressure differential between the injector and producer well was established when the short production-tubing string was extended. The results for this study will assist SAGD producers in re-evaluating the position of the short production-tubing string and find the most economical position for this string. This paper creates the foundation for further simulation efforts to incorporate a discretized model with the build section coupled to the reservoir. This will allow production engineers to optimize bitumen production by simultaneously simulating the reservoir and wellbore strings together. However, it must be kept in mind that the sensitivity study outlined in this paper only includes different placements of the short production-tubing string while keeping all other parameters constant. More work should be done in order to evaluate the interrelated effects of changing the location of the short production-tubing string with other wellbore and reservoir parameters.

Formulations with a much reduced MoS2 content while maintaining a product performance and with an alternative solid additive that would result in a product performance, both meeting or exceeding that of the current formulation based on a specified MoS2 content, were developed. The performance of products containing Solid Lubricants SL1 and SL1A was very close to the performance of the current product containing 3% by wt MoS2. The performance of products containing a synergistic mixture of Solid Lubricant SL2 and MoS2 in the ratio of 4:1 by wt was identical to the performance of the product containing 3% by wt MoS2. The performance of the product containing a synergistic mixture of Solid Lubricant SL2 and Solid Lubricant SL3 in the ratio of 4:0.3 by wt was also identical to the performance of the product containing 3% by wt MoS2. The MoS2 in a grease formulation can be lowered or eliminated while maintaining the same product performance to meet the OEM product operating service requirements. Source
