Abstract: Systems and methods for automated fluid sampling for tracer testing are described. In one aspect, an automated fluid sampling system includes a pressurized line, such as a production well or an injection well connectively and a fluid separation vessel receiving sample fluids therefrom. The fluid separation vessel includes a plunger and is configured for gravity-mediated phase separation of the sample fluids into a plurality of aqueous, organic and/or gas phase fluid fractions and includes pluralities of inlet and outlet ports for mediating flow of sample fluids therethrough. At least one purging fluid source, such as a gas or liquid, is used for driving the plunger. Sample fluid collection vessels receive phase-separated sample fluids from the fluid separation vessel. Pluralities of fluid lines and solenoid valves operatively link the pressurized line, purging fluid sources, sample fluid collection vessels, and disposal vessel to one another, whereby a controller selectively manages the automated flow of fluids through the various fluid lines.

Abstract: Aspects of the invention relate to compositions and methods that are used for the remediation of near-wellbore damage in regions of formations near injection wells in communication with subterranean reservoirs. The damage is caused by previous injection of a polymer emulsion into the injection well. A specific aspect is a method of injecting into the subterranean reservoir a composition containing an olefin sulfonate, a sulfosuccinate, and a chemical selected from an alcohol alkoxylated sulfate, an alcohol alkoxylated carboxylate, or a combination thereof. The polymer emulsion is thereby dissolved, cleaned and/or flushed away from the region near the injection well.

Abstract: The present disclosure provides techniques for inline injection of water and chemicals for a dump flood. The techniques include collecting water from a source reservoir into a water collection zone of an adjacent water injection well, and injecting a chemical solution into the water injection well. The water and the chemical solution are then mixed downhole in a mixer, such as a static mixer. The mixed injection fluid is then directly injected into an adjacent target reservoir.

Abstract: Aspects of the invention relate to compositions and methods that are used for remediation of near-wellbore damage. A specific aspect is a composition comprising an olefin sulfonate, a sulfosuccinate, and a chemical selected from the group consisting of an alcohol alkoxylated sulfate, an alcohol alkoxylated carboxylate, or a combination thereof.

Abstract translation: 描述用于示踪剂测试的自动化流体采样的系统和方法。 一方面，自动化流体采样系统包括加压管线，例如生产井或连接井，以及从其接收样品流体的流体分离容器。 流体分离容器包括柱塞并且被配置用于将样品流体重力介导相分离成多个水相，有机和/或气相流体馏分，并且包括用于介导样品流体流过其中的多个入口和出口。 使用诸如气体或液体的至少一个清洗流体源来驱动柱塞。 样品流体收集容器从流体分离容器接收相分离的样品流体。 流体管线和电磁阀的多个可操作地连接加压管线，将流体源，样品流体收集容器和处置容器彼此清洗，由此控制器选择性地管理通过各种流体管线的流体的自动化流动。
