...Thermal Stability Testing via Static Aging Abstract High-temperature production well design and equipment installation, particularly for deep petroleum reservoirs, geothermal wells, and steam injection applications, present a multitude of challenges for operators due to the elevated thermal...

...Impact of Solution Gas Others have reported that solution gas tends to breakout of the bitumen during the SAGD process. In both physical models and numerical simulations with live bitumen, the gas liberated by steam injection tends to collect in the upper peripheral area of the steam chamber...

... Abstract This work describes the development of a hydrodynamic and heat transfer mechanistic model for steam flow in a steam injection process. The problem of two-phase steam flow in pipelines and wellbores has been solved recently by using available empirical correlations from the petroleum...

... are shown in Figs. 6 through 9 and Fig. 11 . Field application case A field application case of steam injection with CO 2 and surfactant in a horizontal well in a heavy oil reservoir is studied. The P horizontal well is located at the Z block of Shengli oilfield, China. The reservoir depth...

Also the developed model represents an effective tool to predict the steam injectivity profile and to understand the interesting anomaly related to temperature-depth distribution. Moreover, the developed model will be used to optimize Steam flood process and steam pattern well...

... for a specified range of crude volume. Third, the implementation of in situ upgrading significantly reduces energy consumption since the same energy from the steam injection is used to produce and upgrade the oil. Finally, in situ upgrading is more environmentally friendly, yielding lower quantities of byproducts...

...). A huge amount of oil is contained in such reservoirs without any technological breakthrough for improving the recovery efficiently. Introduction Abstract In heavy-oil recovery, although steam injection has no alternative in many circumstances, it may not be an efficient process under certain...

We describe here a simulation study of one application related to modifying the variation of oil viscosity in the reservoir prior to steam injection. The methods make use of mobile water...

... designed to allow passage of hydraulic fluid internally. This well was completed in sands zones R4 and T with electro submersible pump (ESP) and is producing 2,500 BPD of 11.5 API, which is 50% more production than conventional single zone completion in this area. Hydraulic Set Steam Injection...

... investment that need accurate production and reservoir data and have difficult processing techniques. This data includes: Real time measurement: good reservoir and steam chamber monitoring and steam injection versus oil production surveys. Cost reduction: steam oil ratio (SOR) optimisation, due...

... Abstract Thermal methods for enhanced oil recovery account for the large share of the world's production. Steam flooding is one of the oldest commercial methods to enhance the heavy oil recovery. In due respects, experiments of steam injection into a sand pack were performed to study...

... Abstract As a result of hydrothermal stress induced by steam injection in reservoirs, heavy crudes undergo chemical transformations, called aquathermolysis, the extent of which depends at least on steam temperature, injection history and both crude and mineral matrix physicochemical properties...

... Abstract This research effort discusses the effects of a comprehensive range of fluid, rock-fluid and operational properties on the efficiency of steam injection in naturally fractured reservoirs with heavy oil. For this purpose, a fully implicit dual-porosity/dual-permeability simulator...

In this paper we describe the gravel-pack techniques applied to minimize the rapidly declining rate of production in horizontal alternate steam-injection wells. We explain the method used for screen and gravel-size selection and summarize the completion...
