Abstract

Methods and systems for predicting downhole measurement data at the earth surface include predicting a first estimate value of a property of interest using a first processor in a downhole tool using a first predictor and predicting a second estimate value of the property of interest using a second processor of a surface unit and using a second predictor, the second predictor including identical data processing as the first predictor. A measurement value of the property of interest is obtained using a sensor arranged in the downhole tool. The first processor compares the measurement value with the first estimate value and determines if the measurement value is within a predetermined threshold relative to the first estimate value. In response to the measurement value being within the predetermined threshold of the first estimate value, a wellbore operation based on the second estimate value is performed using the second processor.

Claims (16)

2. 1. A method for predicting downhole measurement data at the earth surface, the method comprising: predicting (604) a first estimate value (404) of a property of interest using a first processor (522) arranged in a downhole tool (116, 318) in a borehole (104, 312, 502), the first processor executing a first predictor (512); predicting (604) a second estimate value (404) of the property of interest using a second processor (526) arranged in a surface unit (506) at the earth surface and outside the borehole, the second processor executing a second predictor (516), the second predictor including identical data processing as the first predictor, such that when the same input is provided to each of the first predictor and the second predictor, the first estimate value predicted at the first processor is equal to the second estimate value predicted at the second processor; obtaining (606), by a sensor (132, 542, 544), a measurement value (402) of the property of interest, wherein the sensor arranged in the downhole tool; comparing (608), at the first processor, the measurement value with the first estimate value predicted by the first predictor; determining (610) if the measurement value is within a predetermined threshold relative the first estimate value; and performing a wellbore operation based on the second estimate value of the property of interest, using the second processor, in response to the measurement value being within the predetermined threshold of the first estimate value.
3. 2. The method of claim 1, further comprising: Transmitting (616) the measurement value from the downhole tool to the surface unit using the first processor in response to the measurement value being outside the predetermined threshold; replacing (618), by the second processor, the second estimate value with the transmitted measurement value in response to receiving the transmitted measurement value at the surface unit; and predicting (604) a subsequent second estimate value with the second predictor based on the transmitted measurement value.
4. 3. The method of any preceding claim, wherein, in response to the measurement value being within the predetermined threshold from the first estimate value, the downhole tool is configured to not transmit the measurement value to the surface unit (612).
5. 4. The method of any preceding claim, wherein the property of interest is one of a characteristic of a drilling operation and an earth formation property.
