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.
There are different types of information transmitted by the software one being the direction of the well. Real time directional surveys and its transmission are very possible. Measurement of the azimuth and the inclination of the hole at that location are done by the magnetometers and accelerometers. There is therefore real time transmission from the site to the surface.
The location of the wellbore can be obtained by data taken at intervals between ten meters to five hundred meters send to the surface. The informative shows the company if the location drilled is or is not within their exploration block. It is not necessary to get this information when you wellhole is being drilled vertically or at a very small angle from the vertical line.
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.
Information on the drilling mechanics on the drill bit is also send by the software. Downhole temperature, smoothness of rotation, and operation speed of the rotation are some of the measurements taken. Weight and torque of the bit information aid in operating more efficiently. The driller monitors the tools used from this information to make sure they are working as per the technical specifications. Geologists have a use for this information which is to determine the rock formation of that area.
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.
There is also the measurement of natural gamma rays measurements at the well using internal gamma ray sensor installed in MWD tools. The sensors cost a lot, are compact and able to take measurements when drilling unmodified drill collars. Compacts and cheap sensors will do unmodified drill collars during operations. MWD software cuts the various process costs and increases the lifespan of the drill bits.
There are two types of transmission of data on drilling; either mud-pulse telemetry method or electromagnetic telemetry. The functioning of the mud-pulse telemetry method is where the mud valve deep down the hole restricts the flow of slurry thus brings about the differences in pressure which are sent to the surface for further analysis. There are three types of pulses; positive, negative pulse or continuous wave.
Electromagnetic telemetry method of data transmission by the MWD software involves generation of altered voltage different in the upper part and the lower portion of the electrical insulator used in the drillstring. A wire attached to the wellhead on the surface and another wire attached to the rod form the electrodes of a dipole antenna. From these electrodes the voltage signals are obtained and analyzed to give information.
