MWD which means Measurement While Drilling is measurements taken by drilling companies when the well is drilled at an angle with respect to the vertical line. MWD drilling software is used to take these measurements and analyze them. This crucial data in transmitted during operations to the surface where it is used to produce a path of the oil well in three dimensions.
One of the information transmitted by the software is on the direction of the well. They are able to directional surveys and transmitting them in real time. The magnetometers and accelerometers in it are utilized to measure the azimuth and also the angle at which the hole drilled incline at that location. This data is then transmitted immediately to the surface.
Analysis of data is done on the surface before calculation of the location of the wellbore after data transmission which takes data from 10m to 500m in intervals. This information is as crucial as it being prove enough that the company is not doing any operation outside its permitted site or circumference. It may not be used when creating vertical holes or near vertical direction because it is quite expensive.
The surveys is mainly used in directional-drilling. Directional-drilling forms the main or core part of any survey. Finding and moving towards the target zone of the well will be made easier by this information. Directional-drilling is aided by MWD by the provision of tool face measurements which uses downhole mud motors with bent housing or bent.
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.
The internal gamma ray sensor using installed in MWD tools measures the natural gamma rays values at the well. The sensors are inexpensive, compact and are able to take the measurements when working on unmodified drill collars. MWD computer programs cuts the process costs and increases the life-span 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.
MWD software analyzes voltage signals transmitted through electromagnetic telemetry method. These voltage signals are generated as a result of altered voltage differences in the lower and upper parts of the electrical insulator in the drillstring. Wires attached to the wellhead and the rod form the electrodes for information transmission.
