Method for making a record of drilling a property of formation, and to compensate for movement of the measurement values of a measurement tool.A method to compensate for movement of the tool is provided.In a method of implementation, the method includes passing a registration tool for drilling through a boring hole, obtain a series of measurements of the response of the tool.And get a series of measurements of the position of tool associated with the measurements of response of the tool.Measurements of the position of the tool are, preferably, the distance between the axis of the tool and the axis of the boring hole.The measurements of the position of the tool are, preferably, examined to determine if the tool was moving while the tool was measurements.For measurements made while the tool is moved, the measurement time interval is preferably divided into subintervalos, each having a corresponding position of the tool.A property of the tool (such as resistivity) is estimated, and the response of the tool expected for each position of the tool is calculated.The answers of the expected tool are combined to form a response of the tool model, i.e., the response of tool that should be expected for a tool in motion.The response of the tool model is then compared with the response of the tool measure.The estimate of the property of the formation is adjusted and the process is repeated until the response of the tool model is substantially equal to the response of the tool measure.
