Compositional Variation in SAGD
SPE Annual Technical Conference and Exhibition, 2015Abstract In last two decades, the steam assisted gravity drainage (SAGD) has been successfully implemented for increasing the oil recovery from bitumen reservoirs (Butler et al. 1981, Butler and Stephens 1981). This paper describes a detailed study of compositional variation in a SAGD process.

Compositional Mechanisms in SAGD and ES-SAGD With Consideration of Water Solubility in Oil
SPE Canada Heavy Oil Technical Conference, 2016Abstract Experimental data have shown that the solubility of water in the oleic (L) phase (xwL) can be significant at elevated temperatures. However, xwL was not properly considered in prior studies of SAGD and ES-SAGD. The main objective of this research is to present a detailed study of compositional mechanisms in SAGD and ES-SAGD ...

Review of Reservoir Parameters to Optimize SAGD and Fast-SAGD Operating Conditions
Journal of Canadian Petroleum Technology, 2004Abstract Although high recovery efficiency is expected from the SAGD process, high steam production costs and the substantial volumes of water required have made us focus on more effective recovery methods. One such method is the Fast-SAGD process which utilizes one or more offset horizontal wells parallel to the ...

Introduction During the recent AEUB Chard Leismer Gas Over Bitumen Hearing, there was a considerable amount of technical evidence presented on a wide variety of SAGD technology. One aspect that was different from the last such hearing (Surmont) was the introduction of geomechanics related to the SAGD process.

Petroleum Science and Technology, 2014
Steam assisted gravity drainage (SAGD) is a promising technique for production of heavy oil reservoirs. Various new methods have been developed based on SAGD and one of them is SAGD-ISSLW. In this study, a comparison between SAGD and SAGD-ISSLW was investigated, and then effects of operational parameters and reservoir variables on SAGD-ISSLW ...

SPE International Conference on Horizontal Well Technology, 1998
Abstract The steam assisted gravity drainage (SAGD) process has emerged as an effective technology for the recovery of oil from oil sands deposits that are deeply buried for surface mining. In general, the process involves drilling paired horizontal wells, one well above the other and separated by a distance, near the bottom of the oil ...

Improving the Performance of SAGD
SPE International Thermal Operations and Heavy Oil Symposium, 2005Abstract In the recent years several SAGD projects have been initiated for the recovery of heavy oil and bitumen. Every operator is coming across new learning almost every day, although most of this information is proprietary. This paper presents a general discussion, supported by simulation and analytical results, on the different ...

SPE Journal, 1999
Summary Experiments on initial stages of the steam-assisted gravity drainage (SAGD) process were carried out, using two-dimensional (2D) scaled reservoir models, to investigate production process and performance. Expansion of the initial steam chamber, its shape and area, and its temperature distributions were visualized with video and ...

Mobil's SAGD Experience at Celtic, Saskatchewan
Journal of Canadian Petroleum Technology, 1999Abstract Following the 1996 success of two Single Well-Steam Assisted Gravity Drainage (SW-SAGD), wells in the Celtic Field, Saskatchewan, Mobil Oil Canada piloted a Dual Well-Steam Assisted Gravity Drainage (DW-SAGD), well pair in 1997. The well pair was located in the Sparky-General Petroleum, "channel" sands with
