Information Transmitted By MWD Drilling Software

By Karina Frost


MWD which in full is Measurement While Drilling is measurement taken when drilling on an angle of inclination to the vertical line. These measurements are taken by the MWD Drilling Software. This data is used to produce a 3-D plot of the path of the oil well. This software will transmit crucial information to the operator during operations.

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 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.

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.

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.

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.

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.
