... Abstract With the advent of horizontal wells a distinct change is tacitly taking place in our approach to the improved recovery of heavy oil: from displacing mobilized oil in a flood pattern from injector to producers over long distances of the order of hundreds of meters to short-distance oil...

... reduced. Results proved successful and 40 horizontal wells were drilled over the next two years. In July 2005, Trident and partner Nexen announced Corbett was the first commercial Mannville project in Alberta. In 2006, the multilateral well design was introduced to reduce drilling and artificial lift...

... and successfully tested on a field case study. The new model exhibits the expected anisotropy of damage. Introduction Anisotropic formation damage has been studied by many researchers, especially for horizontal wells. However, in all previous work it has been assumed that the damage intensity in different...

... to the performance of nearby Classic SAGD pairs. 1 Classic SAGD is defined in this paper as two horizontal wells of the same length separated by a relatively short vertical distance (typically 5 7 meters), with the injector on the top and the producer on the bottom. Horizontal wells could also be placed...

... Abstract Four major factors affecting horizontal well gravel pack were studied using a 3-D simulator developed for horizontal well gravel packing. The factors were settling effect, gravel concentration, injection rate, and carrier fluid viscosity. The gravel pack process was simulated...

... results in upward movement of the overburden, and thus heaving of the free ground surface. This paper proposes an analytical method to estimate the surface heave induced by the steam injection. The method was used to investigate the surface heave profiles under horizontal well injection. It was found...

... Abstract The method and semi-analytical model are proposed to determine near wellbore formation heterogeneity profile distribution along horizontal wells of SAGD projects. To determine quantitative permeability distribution, temperature recovery is used, provided by systems of distributed...

... on the performance of infill wells in mature light oil carbonate reservoirs. First, we reviewed the performance of two Mississippian pools in SE Saskatchewan (Williston Basin). Here, the horizontal wells performed noticeably better than the contemporary vertical infill wells. In Alberta however, in the three...

... Abstract Horizontal wells are nowadays more often exercised in developing oil and gas fields because of their potential benefit of increasing the drainage area. Complex reservoir structures often impose the use of numerical simulation when interpreting the transient pressure behaviour...

... Abstract A 3-D numerical simulator for horizontal well gravel packing is developed. The model was developed based on the fundamental laws of physics by solving for an overall conservation of forces during the placement of the gravel in the horizontal well bore. The equations of continuity...

... Abstract The accuracy of the production forecast of fractured horizontal well not only affects the result of the optimum design and economic evaluation, but also affects the success and effectiveness of the fractured horizontal well. Therefore, it is quite essential to present new models fit...

..., corresponding horizontal wells produced 14 000 to 20 000 m3, especially in heavy oil waterflood projects. However, in several carbonate L- M oil pools the vertical wells performed as good or better than the corresponding horizontal. In an earlier study2, we had observed that whereas performance of individual...

... Abstract Interference tests provide valuable information about reservoir characteristics such as aerial average transmissibility, storativity, and degree of communication between wells. Due to the larger radius of influence and larger contact area of a horizontal well with the formation than...

... Abstract Many simulation studies were conducted about the importance of perforated welllength on horizontal well performance. All of these studies suffered from their dependence upon theoretical models, which lack plausibility due to the lack of accurate experimental and/or field data...

In this area, although the most porous limestone and coarse-grained, dolomitized lithologies have been successfully produced using vertical wells, most production from the tighter, largely undolomitized rocks has been achieved only since the advent of horizontal drilling. Here, some 56 horizontal wells have...
