Method and apparatus for temperature compensation of gamma tools in MWD environments. The higher the gamma-ray count rate, the larger the clay content and vice versa.

Count rates vary about a mean value, and counts must be averaged over time to obtain a reasonable estimate of the mean. Method and apparatus for an improved formation density indicator using pulsed neutron instruments. Potassium 40 decays directly to stable argon 40 with the emission of 1.

Formation evaluation gamma ray – Wikipedia

Systeme de diagraphie spectrale a rayonnement gamma et procede de traitement de spectres de rayonnement gamma. Low-noise method for performing downhole well logging using gamma ray spectroscopy to measure radioactive tracer penetration. The peak of thorium series can be found at 2.

Well-logging tool with azimuthal and spectral radiation detectors and related methods. The diargaphie topology in Norway makes for quite a beautiful and interesting set of data! Geovista have supplied a ary state of the art logging system equipped to provide borehole evaluation data for geo-technical analysis along the proposed line.

In addition, all radioactive phenomena are random in nature. The decay process is usually accompanied by emissions of alpha, betaand gamma radiation.

It also provides the basis for establishing the optimum tunneling method and of course reduces the risk gwmma lengthy and costly delays that may arise due to unforeseen tunneling conditions. The detector crystal is affected by hydration and its response changes with time. Method and apparatus for anomalous radioactive deposition compensation in spectral gamma ray well logging.

Computer processing of borehole diagrapgie surface electromagnetic transmitter survey data. We have interesting upcoming projects and so are looking forward to welcoming a qualified candidate to the team. CA CAA1 fr Language Portal of Canada Access a collection of Canadian resources on all aspects of English and French, including quizzes. From Wikipedia, the free encyclopedia. If the resultant isotope is not stable, it undergoes further decay until a stable isotope forms.

Figure 1 shows the energies of emitted gamma-ray from the three main isotopes. You will need to have experience in the following: A2 Designated state s: The artificial formation simulate about twice the radioactivity of a shale, which generates API units of gamma radiation.

Natural radioactivity is the spontaneous decay of the atoms of certain isotopes into other isotopes. Apparatus and methods for determining gas saturation and porosity of a formation penetrated by a gas filled or liquid filled borehole.

Neutron logging tool having source and target with deuterium-tritium gas admixture. Radiological well logging methods and apparatus for reducing the effect of activation from the detector crystal.

In gammaa, the log is also used for correlation between diwgraphie, for depth correlation between open and cased holes, and for depth correlation between logging runs. Shales and clays are responsible for most natural radioactivity, so gamma ray log often is a good indicator of such rocks.
