... conditions. This paper discusses the need for horizontal steam injection wells, steam distribution control, and the current "state-of-the-art" horizontal steam injection completions or, more accurately, the lack of steam profile controls currently available. Also discussed are the three areas critical...

... originally to address environmental concerns associated with permafrost regions on Alaska’s North Slope, has evolved and been adapted for use in heavy oil fields around the world to reduce heat losses in steam injection wells, improve economics, and improve efficiency of heavy oil recovery. This paper...

... Abstract Steam injection is a successful operation to increase heavy-oil production, but the casing failure rates in steam injection wells are very high. Severe thermal-loading to the casing is resulted from steam injection operations and is attributed to the high casing failure rates...

... and optical compensation. Field tests of our multiparameter sensor product in steam injection wells over more than one year have demonstrated system performance specifications and excellent robustness. The optical fiber sensor system operates based on a variation of the modal domain concept discussed...

... Abstract Offset steam injection wells within a certain radius are typically shut in within a certain time period before drilling an in-field (increased density or replacement) well. The basis of this practice is that the reservoir pressure will eventually decrease to a minimum value, allowing...

... ABSTRACT A mathematical model was developed to evaluate wellbore heat losses and two-phase pressure drop in concentric-pipe steam injection wells. The model is based upon the equations for conservation of mass, momentum, and energy within each pipe, heat loss in the wellbore, and heat...

... under a variety of possible completion designs for steam injection wells in the S1-B zone of the Cat Canyon Field located near Santa Maria, California. These results show that under certain completion conditions, heat losses could be as high as 22 percent. Introduction In 1974, Getty Oil Company...
