摘要： A logging-while-drilling density sensor includes a gamma ray source and at least two Nal detectors spaced apart from the source for determining measurements indicative of the formation density. A magnetometer on the drill collar measures the relative azimuth of the Nal detectors. Measurements made by the detectors are partitioned into bins defined by azimuth. A compensated bulk density is determined for selected ones of said azimuthal sectors that meet a threshold test related to a minimum difference of measurements or a minimum correction. The method of the invention may also be used with neutron porosity logging devices.

摘要： Systems, devices and methods for evaluating a volume of interest of an earth formation. The method may include modeling the volume as being in one of two states using a plurality of measurements corresponding to a plurality of measurement types, and may include assigning a relative credence indicator value to each measurement in dependence upon the corresponding measurement value and using the relative credence indicator value for each of the plurality of measurements to estimate the state of the volume by estimating the state of the volume using a state indicator value derived from the relative credence indicator values. The first state of the two states may correspond with presence of a condition associated with the formation, and the second state of the two states may correspond with absence of the condition. The condition may comprise presence of a fluid in the formation having a selected fluid type.
