Horizontal-Well Pressure Analysis
SPE Formation Evaluation, 1987SummaryThis paper presents an analysis of the pressure-transient behavior of a horizontal well or a drainhole. The performances of horizontal wells and fully penetrating vertical fractures are compared. Dimensionless wellbore pressures are computed for two classic boundary conditions: infinite conductivity and uniform flux.

Pseudo-Horizontal Well: Alternative to Horizontal and Vertical Wells
Proceedings of International Conference on Horizontal Well Technology, 1996Abstract Horizontal wells are getting more and more widely used in oil and gas fields development due to plenty of its merits. However, there are examples when horizontal well drilling did not justify hopes. It is shown in this paper, that layered and anisotropic structure of the reservoir may lead to decrease of initial oil flow rates ...

Modeling Well Performance for Fractured Horizontal Gas Wells
Proceedings of International Oil and Gas Conference and Exhibition in China, 2010Abstract In tight gas reservoirs, horizontal wells have been used to increase reservoir contact and hydraulic fracturing has been applied to further extend the contact of the reservoir. Point source solution has been used to describe the flow behavior.

Pressure Transient Analysis for Horizontal Well and Multi-Branched Horizontal Wells
Proceedings of International Conference on Horizontal Well Technology, 1996Abstract Transient pressure for cases of a horizontal wellbore axis with any angle inclined to a fault or a constant pressure supply boundary in anisotropic formations were studied. This axis parallel to or perpendicular to a fault is only its a simple special case.

HORIZONTAL WELL SAND CLEANOUTS
Proceedings of SPE International Heavy Oil Symposium, 1995Abstract This paper discusses sand problems occurring in Horizontal Wells located in NE Alberta and NW Saskatchewan, Western Canada. These wells are completed in the heavy oil sands at 450–750 m TVD. Typical completions utilize 0.625 mm (0.025 in.) slots in liners 500m to 1200m long. The average length is approximately 900m.

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 ...

Horizontal Well IPR Calculations
SPE Annual Technical Conference and Exhibition, 1996Abstract This paper presents the calculation of near-wellbore skin and non-Darcy flow coefficient for horizontal wells based on whether the well is drilled in an underbalanced or overbalanced condition, whether the well is completed openhole, with a slotted liner, or cased, and on the number of shots per foot and ...

Advanced Horizontal Well Model
North Africa Technical Conference and Exhibition, 2010Abstract A new semi-analytical model developed allows making fast modeling of the heterogeneous reservoirs, drained by a single horizontal well with multiple transverse hydraulic fractures. It is assumed that: –the flow in the reservoir obeys Darcy law;–the fluid contains only one phase;–the reservoir permeability tensor is a function of

Well-Control Operations in Horizontal Wells
SPE Drilling Engineering, 1991Summary This paper analyzes well control for horizontal wells. It presents a computer model for predicting the pressure behavior in a horizontal well during gas-kick removal and analyzes the simulation results for several field conditions.
