Horizontal Well Workover Experience
SPE Latin America Petroleum Engineering Conference, 1990ABSTRACT In recent years, horizontal operations involving drilling and well completion techniques in the oil and gas industry have increased considerably, and the main reasons for this are economic feasibility and good production results.

Productivity of Multifractured Horizontal Wells
Proceedings of European Petroleum Conference, 1994Abstract Accurate methods are presented to determine the productivity of multifractured horizontal wells with transverse or longitudinal fractures. Charts combined with a simple expression give the relationship between the effective wellbore radius and fracture conductivity, fracture size, wellbore radius, number of fractures and ...

Horizontal Well Performance Simulation
SPE Latin America Petroleum Engineering Conference, 1990ABSTRACT A single well, single phase, r-θ-z simulator was used to analyze a well test conducted in a horizontal well. Apart from the usual features of general numeric simulators, the simulator used for this work accounted for the effects of wellstorage, variable skin on different portions of the wellbore, turbulent flow, cross-flow ...

Multirate Test in Horizontal Wells
Proceedings of SPE Asia Pacific Oil and Gas Conference and Exhibition, 2002Abstract During a pressure drawdown test, it is quite difficult to hold a constant rate long enough to achieve the test requirements, especially for horizontal wells. Any change in rate, if not taken into account, can lead to erroneous results. Furthermore, pressure drawdown tests are not suitable in sand producing wells.

The Effect of Well Trajectory on Horizontal Well Performance
Proceedings of International Oil & Gas Conference and Exhibition in China, 2006Abstract Horizontal wells provide extended contact with the reservoir, and have unique advantages over vertical wells in many applications. As nominally horizontal wells get longer and follow more complicated trajectories, wellbore hydrodynamics becomes an important issue on well performance.

Proceedings of International Conference on Horizontal Well Technology, 1996
Abstract From 1991 to the end of July 1996, 105 horizontal wells with a total of 175 lateral legs have been drilled in the Weyburn Unit, Southeast Saskatchewan. They produce from a complex, naturally fractured carbonate reservoir that has been under waterflood for over 30 years. PanCanadian, as operator, has drilled

Interference Testing of Horizontal Wells
Proceedings of SPE Annual Technical Conference and Exhibition, 1991ABSTRACTSolution to the problem of interference testing of horizontal wells is a major step forward in understanding the fluid flow behavior of horizontal wells and, therefore, to the efficient implementation of the horizontal well technology.

The Analysis of Horizontal Extension Capability in Horizontal Wells
Advanced Materials Research, 2014It is critical to understand whether the available drilling assembly could meet the requirements of drilling design during the design and drilling of horizontal wells. This paper pointed out several limitations on horizontal extension capability of horizontal wells and provided judging criteria of the limit of horizontal extension based upon the ...

Analysis of Interference Tests with Horizontal Wells
SPE Annual Technical Conference and Exhibition, 2003Abstract One of the common assumptions used in horizontal-well interference test analysis is to ignore fluid flow in an out of the horizontal observation well and represent it by an observation point. In some cases, the active well is also approximated by a vertical line source.

Cost/Benefits of Horizontal Wells
Proceedings of SPE Western Regional/AAPG Pacific Section Joint Meeting, 2003Abstract This is a summary of state of the art horizontal well technology and a review of the economic benefits of horizontal wells. The paper describes various reservoir applications of horizontal wells from primary recovery to EOR applications. The paper includes field examples of different applications.
