曼加拉 (Mangala) 是印度一个大型低盐度优质河流油田，其储罐石油初始储量 (STOIIP) 超过 10 亿桶含蜡和中等粘稠原油。水基化学提高采收率 (EOR) 已被认为是提高水驱采收率的最合适技术。整篇论文的目的是描述 Mangala 的碱性/表面活性剂/聚合物 (ASP) 配方开发，在撰写本文时涉及 30 多次岩心驱替，配方设计随着时间的推移而变化。
自2004年发现以来，Mangala油田一直被视为优秀的化学EOR候选地。主要油藏单元分为下Fatehgarh地层和上Fatehgarh地层。这些单元从上到下细分为FM1至FM5 5个水库单元。
Mangala含有蜡质低硫原油，其重力范围为油/水接触面附近的20°API至油柱中的28°API。
Mangala is a large low-salinity, high-quality fluvial oil field in India with stock-tank oil initially in place (STOIIP) of more than 1 billion bbl of waxy and moderately viscous crude. Aqueous-based chemical enhanced oil recovery (EOR) has been identified as the most suitable technique to improve recovery over waterflooding. The objective of the complete paper is to describe alkaline/surfactant/polymer (ASP) formulation development for Mangala, which involved more than 30 corefloods at the time of writing, with formulation design changing over time.
The Mangala field has been regarded as an excellent chemical EOR candidate since its discovery in 2004. The main reservoir unit is divided into the Lower and Upper Fatehgarh formations. These units are subdivided into five reservoir units, FM1 to FM5 from top to bottom.
Mangala contains waxy sweet crude oil with gravity ranging from 20 °API near the oil/water contact to 28 °API in the oil column.
