VERTICAL-HORIZONTAL WELLS FOR DEPLETION AND SWEEP

Proceedings of SPE Annual Technical Conference and Exhibition, 1998
Abstract This paper discusses a completion scheme currently being applied in a thick, large, elongated carbonate anticline Middle-East oil reservoir. The new well completion calls for a combination of an open hole horizontal section penetrating the top 10 feet of the reservoir and a cased or un-disturbed vertical ...

Analysis of Interference Tests with Horizontal Wells

SPE Annual Technical Conference and Exhibition, 2003
Abstract 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.

Unconfined Linear Flow to a Horizontal Well

Groundwater, 2005
Abstract The validity of a previously proposed but untested modification to equations for flow to a horizontal well is assessed using a specially developed finite‐difference model. This modification extends confined flow equations to allow the head in the well and the saturated depth at the well to be estimated in unconfined ...

Survey Of Horizontal Gas Well Activity

SPE Gas Technology Symposium, 1996
Abstract This paper presents the results of a survey on horizontal gas well activity throughout the world. The survey was conducted for the Gas Research Institute (GRI) in 1993 and focused on cataloguing the number of horizontal gas well completions and the type of formations in which they were completed.

Combination Production of Vertical And Horizontal Wells

Proceedings of SPE Asia Pacific Oil and Gas Conference, 1995
ABSTRACT In the last few years horizontal wells are becoming increasly important. This paper presents a hydrodynamic method for solving the flow problem of areal water–flooding systems of combinations of vertical and hprizontal wells( 5–spot well pattern and 7–spot well pattern). The potential function, production rate, breakthrough time,

ModelTests for a Horizontal Well

Groundwater, 1970
Abstract This 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.

Perforating the Horizontal Well

Journal of Petroleum Technology, 1989
Perforating 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

Productivity of Horizontal Wells Completed With Screens

SPE Reservoir Evaluation & Engineering, 2002
SummaryAn integrated flow model is developed to simulate the flow into horizontal wells with screens. The model is composed of a multisegment horizontal-well model and a near-wellbore model. The multisegment horizontal-well model predicts the pressure losses in a bounded reservoir.

3‐D seismic and horizontal wells

SEG Technical Program Expanded Abstracts 1991, 1991
The Rainbow evaporite basin, centered on latitude 58°N and longitude 119°W, is situated approximately 900 km from Calgary in the remote northwest corner of Alberta, Canada. It is approximately 30 × 30 km in areal extent with a relatively uneventful surface topography which is covered by muskeg and stunted coniferous forest.
