... Abstract This paper describes planning, implementation, and results of chemical gas tracers used in a gas injection pilot study in a heterogeneous multilayer reservoir, onshore Kuwait. The use of tracer for waterflooding is a common practice to understand and improve field performances...

... of gas injection phase. The pre-flush waterflood was carried out sequentially into four target layers, injecting a range of pore volumes in each layer and gathering wealth of pilot data including Inter-Well Tracer Test (IWTT), PLT/ILT, time-lapse saturation logging, coring, and VIT to assess the impact...

... Abstract Over the last few decades, tracers have provided crucial insights on fluid flow behavior assessing reservoir connectivity. For years, they had been viewed as mostly passive molecules that go with the flow of the injected fluid and uncover pathways between injectors and producers...

... geophysical measurements, water and gas tracers, geochemical, compositional and soil gas analyses, and 4D seismic and surface gravity measurements. Results from monitoring and surveillance technologies provide a better understanding of the reservoir dynamics within the subject area. The results can be used...

... Abstract Objectives/Scope A novel barcoded advanced tracers system has been developed and field-validated in a hydrocarbon reservoir. With a detection scheme that supports automation, this cost-effective tracers system is designed to enable potentially ubiquitous long-term full-field...

... chemical tracer test (SWCTT). During such push-and-pull tests, oil/water partitioning ester partially hydrolyses to a non-partitioning water tracer. A time-lag in back-production time between the injected ester and the alcohol generated in-situ yields remaining oil saturation (ROS) through a simple...

... experiments and simulation study was transferred to the field last year when Single Well Chemical Tracer Tests with water and ASP recipe were conducted in three SAMA wells with successive improvement either in test procedure or in chemical formulation of the ASP. The result of the last test with ASP paid...

... Abstract To obtain improved oil recovery (IOR) it is crucial to have a best possible description of the reservoir and the reservoir dynamics. In addition to production data, information can be obtained from 4D seismic as well as tracer monitoring. Interwell tracer testing (IWTT) has been...

... Abstract The Upper Devonian carbonate reservoir characterization of the Pamyatno-Sasovskoe Oilfield, Volgograd Region, Russia, is based on geological data, geophysical log, hydrodynamic and tracer investigations. The reservoir model based on geostatistical techniques with grid blocks has been...
