... to in his paper. In addition to ensuring safe SAGD operations, geomechanics understanding will be necessary to investigate the potential breaking of interbedded mudstone and IHS (Inclined Heterolithic Stratification), a commonly found geological feature that often are baffle to the upward growth of a SAGD...

... Abstract With SAGD operations, it is often inevitable to have shut-in time and turnaround periods because of facility, operation, and supply issues. During these shut-in periods, the gravity drainage of cooling bitumen and steam condensate continuously raises the liquid level over...

..., a multiphase flow phenomenon arises. When there is multiphase flow, flow patterns should be considered. It is known that, there is a difficulty to predict hydraulic behavior of gas-liquid mixtures due to this flow pattern dependence. During a drilling operation, one of the parameters that should be well...

... to recover the oil. In this work, the focus is on steam-based gravity drainage processes. It has been demonstrated that operating strategy can be altered to improve SAGD performance but it is not clear how well configuration can be changed to improve recovery, energy intensity, thermal efficiency, water use...

.... Three pairs of SAGD operation began in April of 1997 after three months of circulation. Many interesting characteristics were identified in the injection and production history. During the first year of operation, pressure and oil production rates decreased when steam injection rates were reduced. After...

... not attained a commercial operational status but the experience from the field tests is still very valuable, either for other areas of application or even for those situations in which successful procedures may be developed. Most of the field pilots were in the 1970s and 1980s when even the understanding...

... Abstract Computer simulation technology has been widely applied in many drilling engineering areas to simulate drilling engineering problems, optimization, and to train engineers with real drilling operations and/or to handle rare applications and accidents. One of the increasingly applied...

... reservoir, is presented. The genetic algorithm produced an operable process, which could be described as a new combination of pre-existing concepts. The process offers material improvements in thermal bitumen supply costs, as well as recovery factor. Major reductions in the physical steam/oil ratio (SOR...

... with bottom water, top gas or with formations with fine grain sands. Several SAGD projects are in operation in different types of reservoirs in the Cold Lake and Lloydminster areas; some with thick bottom water zones. A performance review is conducted based on the available data for various CSS and SAGD...

... requires continuous data input to maintain valid integrity assessments. This dynamic process of data collection and integration enables continuous analysis and potentially leads to a more proactive integrity management system. The biggest problem for most operating companies in creating a dynamic...

... Abstract Approximately 12 barrels of water are used for the production of each barrel of bitumen in surface mined oil sands operations. Typically, about 70% of this water is recycled, leaving a net trade of about 4 barrels of water per barrel of bitumen production. This water is tied up...

The paper illustrates with field results the benefits of implementing the multiphase metering in PEMEX E&P. MPFM meters have proved to be a reliable system...

... Abstract With the high demand for oil and gas, operators are becoming increasingly interested in unconventional sources of hydrocarbon. One of the major sources in the world is heavy oil, which has been defined by the API as oil that has API gravity of less than 22.3 ° API (extra heavy oil...
