摘要: System and methods of controlling fluid flow during reservoir stimulation treatments are provided. A flow distribution of treatment fluid injected into formation entry points along a wellbore path is monitored during a current stage of a multistage stimulation treatment. Upon determining that the monitored flow distribution meets a threshold, a remainder of the current stage is partitioned into a plurality of treatment cycles and at least one diversion phase for diverting the fluid to be injected away from one or more formation entry points between consecutive treatment cycles. A portion of the fluid to be injected into the formation entry points is allocated to each of the treatment cycles of the partitioned stage. The treatment cycles are performed for the remainder of the current stage using the treatment fluid allocated to each treatment cycle, wherein the flow distribution is adjusted so as not to meet the threshold.

摘要: The present disclosure describes methods and systems for detecting a tracer in a hydrocarbon reservoir. One method includes injecting a tracer at a first location in a reservoir, wherein the tracer mixes with subsurface fluid in the reservoir; collecting fluid samples at a second location in the reservoir; mixing a magnetic surface-enhanced Raman scattering (SERS) particle with the fluid samples; applying a magnetic field to the mixed fluid samples; and analyzing the fluid samples to detect a presence of the tracer in the fluid samples.

摘要: A leak detection method tests a tubing collar of wellbore tubing. The leak detection method can include the steps of introducing tracer gas under pressure to a tubing collar, introducing water to the tubing collar, detecting the tracer gas from a sample obtained outside the tubing collar, controlling a water system, a gas system, and the gas analysis system, flowing the tracer gas under pressure to the tubing collar and then the water to the tubing collar sequentially and allow the sample to flow to a gas analyzer, initially pressurizing the tubing collar with the tracer gas to a first pressure, pressurized the tracer gas to a second pressure, obtaining the sample from outside the tubing collar, and analyzing the sample for the tracer gas by the gas analyzer, and providing an alert that indicates a leak is present in the tubing collar.

摘要: A logging tool may include a stabilization source configured to emit gamma rays, a gamma ray detector configured to collect gamma rays from the stabilization source and a formation and an analysis module. The analysis module may be configured to determine a photopeak of the stabilization source in a gamma ray spectrum including counts of the gamma rays collected by the gamma ray detector and perform resolution calculations using the photopeak to determine a resolution of the gamma ray detector.

摘要: The invention concerns a tracer material for tracing fluid flows from a hydrocarbon reservoir. The tracer material comprises a plurality of separate agglomerates. The agglomerates comprise clusters of particles. The particles carry a tracer composition. A retaining material at least partially overlies the tracer composition. The retaining material retards the release of the tracer material so that the tracer is released at a more constant rate over a longer period than in the absence of the retaining material.

摘要: A gas analyzer system that can detect atmospheric air gasses in drilling mud is used to calculate an actual lag time in a well. The calculated lag time and a theoretical lag time may be compared to estimate a caving percentage in an open hole section of the well.

摘要: A location of a fracture can be determined in a wellbore. Micro-electro-mechanical (“MEM”) devices of different sizes and shapes can be included in a sweep and injected into a wellbore. A MEM reader can be positioned within a downhole tool for detecting MEM devices in the wellbore after a sweep returns to the surface of the wellbore. The MEM reader can be disposed in the wellbore for measuring the position of the MEM devices remaining in the wellbore. A location, size, and shape of a fracture in the wellbore can be determined based on the position of the MEM devices in the wellbore.

摘要: The present invention relates an Integral analysis method of inter-well tracer tests, which integrates and performs continuous feedback to each of the major stage (design, operation and interpretation) allowing quantitative interpretation of these tests. It is presented as a tool to investigate the behavior of injection fluids for recovery of hydrocarbons, as well as for the dynamic characterization of reservoirs. The main advantage of this invention is that it allows a greater certainty in the tracer response and a marked improvement in the sensitivity and quantitative analysis of the test results, since the curves fit both with mathematical models and numerical models. Another outstanding attraction of this invention is the reduction in the costs of testing such applications.
