... 15 , leads to a Hele-Shaw description of the displacement flow. This simplified model considers the 2D "gap-averaged" flow in axial and azimuthal directions; see Figure 1 . A major benefit of this model reduction is the fact that, in the simplest situation, the flow is governed by only the following...

Paper Number: SPE-115003-MS
.... Abstract While using conventional surface launch cementing plugs during cementing operations performed on large diameter surface pipe, significant costs are incurred during the pumping of cement and displacement fluids because of the large volumes involved in the job. Additionally, high differential...

... was injected to displace the gel. The water that carried the proppant, quickly formed viscous fingers through the gel. The gel was observed to form long thin layers which effectively hindered proppant settling and helped transport the proppant further into the slot. This resulted in the formation of proppant...

... because of the relatively low viscosity of the gas. This paper demonstrates how these differences affect the penetration of acid into the formation and the distribution of acid along the wellbore (acid placement). When acid displaces gas in the formation around the wellbore, the favorable mobility ratio...

Paper presented at the SPE Gas Technology Symposium, April 28–May 1, 1996
Paper Number: SPE-35599-MS
... Abstract Carbon dioxide has been used in oil reservoirs for multiple contact miscibility, with methane or nitrogen as the displacing fluid. Carbon dioxide has also been used as an additive for fracture fluids to promote flow back and even as a base fluid for fracturing. A miscible process has...

... Abstract The operation of an aquifer gas storage can be distinguished from the production of a classical gas field by two fondamental points: – the flow rates in an aquifer storage are much more important, with gas/water displacement sometimes becoming instable – the alternating movement...

... in this paper, so these need to be defined. The term, fracture refers to any break in rocks or soil cover that results from natural stress forces, and includes both faults (with either vertical or horizontal displacement) and joints (with very little or no displacement). The term, linears, is commonly used...
