ModelTests for a Horizontal Well
Groundwater, 1970AbstractThis paper deals with the ground‐water flow into a drilled well, consisting of a vertical shaft and radially spaced horizontal intake pipes.It is based on model tests, devised and executed by the author in the Hydraulic Laboratory of the Haile Selassie I University in Addis Ababa, Ethiopia.The author tested the assumption of linearly ...

Thermal Well Testing For a Horizontal Well
Annual Technical Meeting, 1992Abstract Horizontal wells are becoming popular for primary and enhanced oil recovery operations because of unique advantages of horizontal wells in comparison to those for vertical wells. Monitoring the progress of a steam injection process requires a knowledge of the steamswept volume, as this provides a measure of

Geophysics and the horizontal well
The Leading Edge, 1989Peter Gretener, Professor of Geophysics at the University of Calgary, teaches (along with Tom Davis of the Colorado School of Mines) SEG’s Continuing Education course Reservoir Heterogeneity: Causes, Detection, and Remedial Action (previously titled Seismic and Geological Analysis of Fractured Reservoirs). Gretener obtained his doctorate from the Swiss

Fracturing Pressures for Horizontal Wells
Proceedings of SPE Annual Technical Conference and Exhibition, 1992ABSTRACT A fully horizontal well, drilled at an angle from the fracture plane, will experience a potentially substantial increase in the fracturing pressure. The magnitude of this pressure depends on the angle (as the angle increases so does the pressure) and, very importantly, on the value of the intermediate of the three far-field ...

Evaluation of Horizontal Well Production
Proceedings of SPE International Petroleum Conference and Exhibition in Mexico, 2000Abstract When drained volumes want to be increased or to reduce investments with additional drilling wells, we can use horizontal wells as a good alternative for optimum exploitation of the oilfields. This is supported because the horizontal wells productivity becomes higher than in a vertical, due to that they communicate a large area ...

Gravel Placement in Horizontal Wells
SPE Formation Damage Control Symposium, 1996Abstract Long, horizontal gravel packs are viable completions that have been placed successfully in over 20 wells. Extensive field-scale testing has significantly aided the development of field procedures and operating guidelines. Software has also been developed to assist with horizontal gravel-pack design.

Perforating the Horizontal Well
Journal of Petroleum Technology, 1989Perforating a horizontal well may seem no different from Perforating a horizontal well may seem no different from perforating a vertical well. Horizontal well attributes, which perforating a vertical well. Horizontal well attributes, which are extremely attractive for fluid recovery and reservoir management. are controlled or enhanced only partially by

Production Transformation in Horizontal Wells
International Petroleum Technology Conference, 2013Abstract: Pan Orient Energy (POE) recognized that horizontal wells maximise fractures' intercept, thus improving drainage area for oil recovery. However, production data indicated horizontal wells on standalone basis, cannot guarantee the optimum performance required. The negative impact of downhole inflow imbalance

Mud and Cement for Horizontal Wells
Proceedings of SPE Annual Technical Conference and Exhibition, 1986ABSTRACT High-angle and horizontal well bores raise many questions concerning the characteristics of mud and cement. This paper is a summary of our knowledge and work on these two subjects. For all research carried out, large or full-scale laboratory test plants were used.

Gravel Packing of Horizontal Wells
Proceedings of SPE Annual Technical Conference and Exhibition, 1987ABSTRACT One hundred percent gravel packing of horizontal wells has been demonstrated in the laboratory using bidirectional (two lift), water slurrified gravel packing. The first lift provides 70–90+% fill. A second, subsequent, reverse direction lift provides both 100% fill and consolidation.
