Measurement While Drilling is abbreviated as MWD. It is used to take the measurement of the inclination angle against the vertical line through the process. MWD drilling software then takes up all these values.The oil well paths are plotted in 3-D using this information. Communication between the operator and the floor is crucial and is provided by this software.
The software transmits information on the direction the well is being drilled. Directional survey can be done by the software and sent in real time. Azimuth and the inclination angle of the drill hole are measured by the magnetometers and accelerometers in it. Immediately information on them has been measured it is transmitted to the surface for analysis
The data transmitted at intervals of 10m to 500m is then analyzed on the surface to calculate the location of the wellbore. It is necessary information for the company since it acts as a proof that it is not operating outside the block it is licensed to prospect. When operating vertically or near vertical direction this technology is not used due to its high cost.
Drilling has to be done is a specific direction or in a directional-drilling. The information that is obtained from the MWD tools guides the driller on steering the process in the direction to the target zone. Bent housing or bent subs aid in directional operations with the MDW providing toolface measurements from the downholde mud motors.
There is the smoothness of rotation, mud flow volume, downhole temperature, the drillstring speed of rotation, and the weight and torque on the bit, this information is sent to the mechanics of the drill bit which leads to more efficient operations. The tools are also used in accordance with their specifications thus cannot break down. Understanding the rock formation of the area is crucial to geologists.
MWD tools are capable of measuring the formation properties and send the data to drillers when drilling is ongoing. They use this information to perform geosteering to the target zone. The information varies from porosity, inclination at the bit, acoustic-caliper, density, and resistivity.
The MWD tool is fitted with gamma ray sensors on the inside which are used to measure the natural gamma rays occurring at the well. They are very compact and cheap and can take measurements of unmodified drill collars during the process. The lifespan of drill bits in greatly increased when using the software and costs of creating the hole reduced.
The data they get during the operations is either transmitted by the mud-pulse telemetry method and electromagnetic telemetry. In the mud-pulse telemetry method the mud valve downhole which restricts the flow of slurry creates pressure differences which are send to the surface as for analysis. It can either be positive, negative pulse/continuous wave.
In electromagnetic telemetry method by the MWD software, altered voltage is generated in the upper and lower part of the electrical insulator then incorporated in the drillstring. There is a wire from both thewellhead on the surface and the rod which form the electrodes of a dipole antenna. These electrodes provide information from analysis of the voltage signals.
