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.
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.
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 core use of the surveys is in directional-drilling. The well may be located at a certain zone and this information helps the driller in steering the process towards that target zone. MWD provides toolface measurements using downhole mud motors with bent housing or bent subs to aid in directional operations.
The software sends information about the mechanics of the drill bit. This kind of information include the downhole temperature, mud flow volume, smoothness of rotation, the drillstring speed of rotation, the weight as well as torque on the dril bit. This info will lead to more efficient operations. It also ensures that the tools used won't fail when drilling because they can be operated within their technical specifications. Geologists use this information to understand the formation of the zone being drilled.
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.
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.
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.
