    摘要： Embodiments of the disclosure may include systems and methods for evaluating gas-contaminated cement. In one embodiment, a vector-valued image of cement state probability may be obtained from an acoustic logging tool, and a maximum a posterior classification of cement state of the vector-valued image may be determined. A vector probability diffusion equation may be used to minimize the total variation of the vector-valued image over a number of interactions to produce a second image. The maximum a posterior classification of cement state the second image may be determined and compared to the maximum a posterior classification of cement state of the vector-valued image. Depending on the comparison, the original image and cement state may be used or a new gas-contaminated image with a different cement state may be generated.

    摘要： A method is disclosed and performed by collecting, by a volumetric sampler (50), a known volume of a sample from drilling fluid (28) exiting a well bore (12) penetrating a formation (14), the sample having a free gas and a dissolved gas. A first quantity of the free gas entrained in the sample is measured by a free gas detection system (52). The sample is transferred to a dissolved gas detection system (54) after the free gas in the sample is measured. The method is further performed by measuring a second quantity of the dissolved gas in the sample by the dissolved gas detection system. A total amount of one or more certain type of gas in a formation is estimated based on the first and second quantities.
