Numerical Simulation of Horizontal Wells

Middle East Oil Show, 1991
ABSTRACT An analytical equation for calculating horizontal well pressure in a simulation model is derived. This equation is very essential for history-matching and predicting the performance of horizontal wells. The derived equation is needed to compute the effective radius which relates the wellbore pressure to the ...

Formation Evaluation of a Horizontal Well

Proceedings of Middle East Oil Show, 1991
ABSTRACT In Upper Zakum Field, the interest in horizontal drilling has continued. A second horizontal well was drilled during the second half of 1989. This necessitated running logging tools for well control and to evaluate the reservoir characteristics. The logging tool selected for this well is that of Sperry-Sun.

Advanced Horizontal Well Model

North Africa Technical Conference and Exhibition, 2010
Abstract 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, 1991
Summary 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.

Potential for Horizontal-Well Technology in the U.S. [PDF]

Journal of Petroleum Technology, 2000
Summary Application of horizontal wells has increased tremendously and had significant and positive results in the U.S. over the past decade. The pace of horizontal drilling for oil has remained high since 1990 (approximately 600 to 1,000 wells/yr).

WELL TRACTORS FOR HIGHLY DEVIATED AND HORIZONTAL WELLS

Proceedings of European Petroleum Conference, 1994
ABSTRACT This paper introduces the oil industry to a new type of downhole tools - the Well Tractors with modular power source designed for running in open hole and inside the completions of horizontal and highly deviated wells. The Well Tractors are used for cleaning, setting and pulling of plugs, operating sliding sleeves,

Optimization of Horizontal Well Placement

Proceedings of SPE Western Regional Meeting, 1996
Abstract In this study the coning time of water and gas as well as the optimization of a horizontal well placement with respect to the gas-oil and water-oil interfaces are examined. A three-dimensional, three-phase, black-oil commercial simulator is used to simulate the simultaneous movement of the gas-oil and water-

Field Performance of a Horizontal Well

Proceedings of Middle East Oil Show, 1991
ABSTRACT This paper presents a field example of a short-radius horizontal drainhole which was completed by sidetracking an existing vertical well. The main reservoir characteristics are unconsolidated sand, high permeability and increasing production water cut due to strongly active bottom water.

Flow In a Constricted Horizontal Well

Annual Technical Meeting, 1997
Abstract Horizontal wells have been used successfully in Canada to recover oil from marginal heavy oil reservoirs in Saskatchewan and Alberta. These reservoirs are often poorly consolidated; recovery operations in these reservoirs are, therefore, usually susceptible to sand production.
