Paper presented at the SPE Canada Unconventional Resources Conference, September 28–October 2, 2020
Paper Number: SPE-199980-MS
...-Darcys. This paper proposes an alternative pulse-decay technique that offers accurate permeability measurements within a considerably short time frame. A radial-flow pulse decay method with a new experimental design is developed, which employs two gas reservoirs of the same volume and two pressure...

... in these complex plays is inevitable. In shale oil reservoirs, EOR is relatively novel compared with in conventional oil reservoirs. The most investigated technique among EOR methods to be applied in shale oil reservoirs is injecting miscible gases which mainly include CO 2 , N 2 and enriched natural gases...

... material balance equation (MBE) to forecast the performance of shale oil reservoirs under natural depletion and huff-and-puff gas injection scenarios. For undersaturated reservoirs, recovery is calculated from the proposed MBE explicitly using a multiporosity effective oil compressibility. For saturated...

Paper Number: SPE-189804-MS
... Abstract In recent years, gas huff-n-puff has proven to be a potential EOR method in unconventional reservoirs. The main mechanism is that the injected gas will penetrate the reservoir matrix and diffuse into the oil phase to extract oil. Gas penetration into the reservoir and oil phase...

Paper presented at the SPE Canada Unconventional Resources Conference, March 13–14, 2018
Paper Number: SPE-189791-MS
... Abstract This paper develops innovative methods for analysis of some important exploration and production problems in shale petroleum reservoirs such as the determination of burial maturity and maturation trajectories, and determination of sweet spots with the use of Modified Pickett plots...

Paper Number: SPE-189784-MS
... Abstract Oil recovery worldwide from conventional reservoirs vary significantly from case to case, but it is sometimes presented at an approximate average of 30-35 % of the original oil in place (OOIP), including primary and secondary recovery. This study shows that proper implementation...

..., and mineralogy of actual tight reservoir rocks. To generate the desired dual-permeability system, fractures are simulated by creating sand-filled branched pathways in the large synthetic core. During a coreflood test, fluids are injected through the peripheral high-permeability belt into the tight matrix...

Paper Number: SPE-189802-MS
... Abstract Confidently establishing single well and/or aggregated production profiles, particularly estimated ultimate recovery (EUR), is both an important and challenging process in unconventional reservoirs. Numerous papers have proposed forecasting techniques, but four fundamental approaches...

Paper Number: SPE-189814-MS
... Abstract The primary goal of this work is to demonstrate that the fractal geometry can be used to accurately model the rate and pressure performance behavior of highly heterogeneous reservoirs such as shale oil/gas reservoirs. There are multi-scale heterogeneities that can hinder modelling...

... the data was easiest to interpret, the incremental production has doubled since the huff-n-puff project started. This paper also proposes methodologies for implementing second generation pilots for unconventional reservoirs. It is important to define clear objectives that characterize the value...

... Abstract Tight reservoirs with low and ultralow permeability must be successfully stimulated to produce at economic oil or gas rates. For this reason, costs of drilling and completing wells are very high in tight reservoirs. In order to reduce these costs, operators have often tried...
