Mukhaizna 是阿曼南部的一个重油田。它是一个多层油藏,自 2007 年以来一直采用蒸汽驱生产。主要砂岩油藏是在每个目标区域使用水平生产井开发的,并配有垂直注入器。尽管大多数模式已经热成熟,但少数地区仍在等待蒸汽驱响应。为了成熟这些领域,使用现有模式和井配置评估、定制和实施了蒸汽辅助重力泄油(SAGD)试点。

SAGD Trial in Omani Heavy Oil Field Overcomes Suboptimal Conditions

This paper describes the potential, challenges, and opportunities of using a modified steam-assisted gravity drainage configuration in the Mukhaizna heavy oil field in suboptimal operating conditions.

Mukhaizna is a heavy oil field in southern Oman. It is a multistacked reservoir that has been producing under steamflood since 2007. The main sandstone reservoirs were developed using horizontal producers in each target zone supported by vertical injectors. Although most of the patterns are thermally mature, a few areas still are awaiting steamflood response. To mature these areas, a steam-assisted gravity drainage (SAGD) pilot was evaluated, customized, and implemented using existing patterns and well configurations.

Mukhaizna Field

The Mukhaizna heavy oil field contains viscous, low-gravity (14–18 °API) crude oil in the shallow Permian-age sands of the Gharif formation.
