... expansion. The model is unique because it assumes the steam injection rate is constant and it permits modeling of the late phase of SAGD when adjacent well pair interference occurs. This leads to a reduction in heat loss to the overburden and a decline in oil production rate. This study examines...

... from larger heat losses through cap-rock and poorer oil mobility under reservoir conditions. A new EOR method, ES-SAGP, is introduced to develop this kind of reservoir. That is to say, non-condensate gas and vaporizable solvent is injected with steam into steam chamber during SAGD. The scaled 3D...

... Abstract Deepwater production well design and equipment installation presents a host of challenges for operators. One of the major problems is the uncontrolled heat transfer to outer annuli and heat loss from the production tubing which can be detrimental to the integrity of outer annuli...

... heater. The heater is used to prevent heat loss in the injection line. A temperature controller on the band heater is used to adjust the temperature of the injected fluid, effectively allowing the user to manipulate it all the way to the entry point of the cell. For steam-petroleum distillate...

Since the first application of water-based insulating packer fluids in the Gulf of Mexico, GOM, over 50 wells have been completed with one form or another of water-based insulating fluid...

... Abstract Flow assurance is one of the major considerations when designing a deepwater completion where undesired heat loss through the deepwater riser accelerates the formation of gas hydrates and the deposition of paraffin and asphaltene. In addition, any planned or unplanned shutdown...

..., this physical model masks the underlying complexity of the two-dimensional axisymmetric heat transfer field. Recent theoretical insights have demonstrated that VIT behaves as a fin around the weld and coupling regions, where up to 90% of the overall heat loss can occur. As a result, VIT does not have a single...

... Abstract Undesired heat loss from the production tubing, or uncontrolled heat transfer to outer annuli contributes to the formation of gas hydrates and causes the deposition of paraffin and asphaltene materials to reduce the production rate. The successful application of thermal insulating...
