... generation plant and distributed to all wells, regardless of their vintage. To de-risk the addition of solvent at the steam header, Cenovus implemented an early rise rate phase SAP pilot at Christina Lake A0201 well pair. The objective of this field pilot was to investigate the effects of butane injection...

The geology of the Lower Grand Rapids formation, sand control selection, and operational practices will be discussed using both laboratory and field data. Petrographic data of oil sand core before and after...

... dilation mechanisms to achieve these preferred results. Using a short-period of small-volume and high-pressure fluid injection, the dilation start-up facilitates the development of a dilated zone that vertically connects the SAGD well pair and is laterally uniform along the length of the well. This zone...

... barriers are categorized by their location relative to the SAGD well pair (vertical and lateral), and by their geometry (thickness and lateral extent). SAGD production was simulated with the reservoir model for a training set of shale barrier configurations. The training set was chosen to try to span...

... Abstract Objectives/Scope Expertise has brought consistency and cost control to drilling and completing steam assisted gravity drainage (SAGD) well pairs. Data shows that the well pad facilities have not achieved the same degree of consistency in scope. Broad differences in specifications...

.... Historically, there are two primary means to achieve startup of a SAGD well pair and are commonly referred to as circulation and bullheading. The circulation process was employed at the Grand Rapids SAGD Pilot on Well Pair 1 and Well Pair 2 in 2010 and 2012 respectively. The circulation process is complex...

... Abstract Circulation of steam during the start-up of a well pair is required for the SAGD process where there is limited fluid mobility, as it helps establish communication for flow between the injector and producer well. The majority of the modeling encountered to date for the circulation...
