Significant permeability improvements were reported in previous papers over a wide range of conditions. In this paper, the result of the first field application is evaluated with a fluid based...

...Leah Miller Guindon Summary The details of the planning, design, and evaluation processes in the application of a new work flow called the Unconventional Reservoir Optimized Completion work flow are discussed. This seismic-to-stimulation work flow demonstrates how a dominant-well-centric process...

.... Using downhole chokes in liquid-unloading applications maintains high flowing sandface pressure conditions. This creates improved reservoir performance and improved well operations, and also saves costs by mitigating surface hydrate formation and fracture sand flowback. 23 3 2015 23 3 2015...

...James J. Sheng; Bernd Leonhardt; Nasser Azri Polymer flooding is the most commonly applied chemical enhanced-oil-recovery technique. This paper provides an update on the status of polymer-flooding technology, focusing more on field applications than on theoretical and laboratory research. It covers...

... important to assess post-CHOPS applications. To this end, we implemented a fractal pattern of different kinds by use of a diffusion-limited aggregation (DLA) algorithm as wormhole domain with a partial dual-porosity approach and a step-by-step simulation technique, taking advantage of a simple mathematical...

... disadvantages of hematite include abrasiveness and higher sag tendency (Howard 1995). The most commonly used acid-soluble weighting material and bridging agent is CaCO3. The specific gravity of CaCO3 is 2.71, which limits its application when high-density fluids are needed to drill deep wells. A high density...

... used in those studies were scattered search, simulated annealing, and genetic algorithm (GA). However, applications of hybrid GA were rarely found. In this paper, we focused on optimization of solvent-assisted SAGD using various GA implementations. In our models, hexane was selected to be coinjected...

Acoustic-wave- testing systems have been applied in the oil and gas industry in dif- ferent applications. For example, exploration seismology is regu- larly used to determine the condition...

... sands at the process level are insuffi- ciently covered in the existing literature, while the majority of CCS papers focus on power generation and not on oil-sands applications. The study covers the leading carbon-capture technologies: pre- combustion, post-combustion, oxyfuel combustion, and chemical...

.... In industrial applications, high-pressure jetting technologies have been used in many industries since the early 1960s (Summers 1995). Many of these applications are dictated by need, such as removing paint from aircraft external surfaces or cutting intricate metal plates. Within the oil industry, hydrajetting...
