20160047231 | GAS WELL INFLOW DETECTION METHOD - A method for detecting or mapping potential influx zones for gas from a geological formation to a gas well with a well head with a valve tree or a choke includes the following steps of:—marking the potential influx zones with tracer systems with corresponding unique tracers—filling the gas well form the surface, through the well head with liquid wherein the tracers have affinity to the liquid,—producing liquid form the well,—consecutively sampling samples from the produced liquid,—to analyze the samples to prove possible presence of one or more tracers or even measure the tracers concentrations. [for then proving possible influx of a back flow of liquid from the influx zones one assume implies the gas pressure and the inflow of a gas form the influx zones]. | 02-18-2016 |
20140343908 | METHOD AND SYSTEM FOR USING TRACER SHOTS FOR ESTIMATING INFLUX VOLUMES OF FLUIDS FROM DIFFERENT INFLUX ZONES TO A PRODUCTION FLOW IN A WELL - A method for estimating influx volumes of fluids to a production flow in a well with two or more influx locations along the well includes arranging tracer sources with unique tracer materials in fluid communication with two or more of the influx zones, each tracer material having a predefined short duration release dose to the fluids in the well, allowing the tracer sources to release the tracer material to the fluids at a given release instant, after the release instant, consecutively collecting samples of the production flow at the topside, analysing the samples for identifying types of tracer material and concentration of the identified tracer materials, based on the concentrations and their sampling sequence and the well geometry, sequence of the separate influx zones, calculating the influx volumes from transient flow models using the calculated influx volumes as parameters for controlling the production flow or for characterizing the reservoir. | 11-20-2014 |
20130268198 | METHOD FOR USING TRACER FLOWBACK FOR ESTIMATING INFLUX VOLUMES OF FLUIDS FROM DIFFERENT INFLUX ZONES - A method of estimating influx profile for well fluids (oil, gas, or water) to petroleum well with influx locations to a production flow, including:—arranging tracer sources with tracer materials in levels of the well, arranged downstream and exposed to the fluids in said influx zones,—each said tracer sources having even release rate to said well fluid,—inducing a transient in the production rate of the entire production flow by shutting in by a valve topside, changing the local exposure times of the tracer sources to the fluid, collecting samples, downstream at known sampling times,—analysing said samples for concentration and type of tracer material from said possible sources,—based on the concentrations and their sampling sequence and the well geometry, calculating influx volumes from flow models. | 10-10-2013 |
20130245948 | EXTRACTING DOWNHOLE FLOW PROFILES FROM TRACER FLOWBACK TRANSIENTS - A production pipe arrangement for a producing petroleum well with at least one of the well fluids (oil, gas, or water) with influx fluids two or more influx zones or influx locations to a production flow in a central production pipe in said well, with tracer sources with distinct tracer materials in known levels of the well, one or more separate delay chambers arranged as a completion component in said pipe, the delay chambers provided with said one or more of the tracers sources arranged in an annular space formed between the completion pipe and a borehole wall, with at least one of said tracer sources arranged exposed to the fluids in at least one of said influx zones, the delay chambers having one or more apertures to the fluid flow in said central pipe. | 09-19-2013 |
20130112400 | WELLBORE FLUID TREATMENT AND METHOD - A wellbore screen including: an apertured base pipe; an intermediate filtering layer including a plurality of metal fibers wrapped helically around the apertured base pipe and a fluid tracing filament wrapped helically about the apertured base pipe, the fluid tracing filament including a filament structure and a tracer carried by the filament structure, the tracer being entrainable in produced fluids in a wellbore environment; and an outer apertured shell over the intermediate layer. A method for producing a wellbore screen, the method comprising: forming a filter tube by wrapping an intermediate layer, including a metal wool fiber strip and a fluid tracing filament, about an apertured base pipe in a helical arrangement under tension; positioning the filter tube within the long bore of an outer apertured sleeve; and securing the outer apertured sleeve and the filter tube together. | 05-09-2013 |
