... a magnetically referenced measurement while drilling tool (MWD) and taken while static, either before, after or sometimes during the connection. The drillstring is often worked to release trapped torque and time is often taken waiting for the survey to be pumped up. All of this consumes rig time and opens...

... Abstract Downhole wireless communication in the form of mud pulse telemetry enabled directional drilling over the past 60 years and has been hugely successful. Technologies like Measurement While Drilling (MWD), Logging While Drilling (LWD), and Geosteering would simply not exist without...

... Abstract Wellbore surveying is essential to deliver the objectives of a well; it is, however, time-consuming, increases the risk of differential sticking, and due to its costs, may not often be done enough to describe the wellbore architecture adequately. Measurement While Drilling surveys...

... to potential cross flow. Detailed measurement-while-drilling (MWD) survey analysis was conducted for the original hole in order to enhance surveys accuracy and minimize positional uncertainty. Typical survey management practices were implemented for Sag and Drilling String Interference; other techniques...

... the isolation tool to verify functionality and to quantify reduction in torsional loads (torque, tangential acceleration) for the measurement while drilling (MWD), mud pulse telemetry (MPT), and logging while drilling (LWD) tools above the tool. In addition, HFTO-related incidents and other drilling performance...

... at stationary interval when drilling operation stops to connect a new stand. A next generation measurement while drilling MWD tool is developed to take a definitive survey while drilling either rotating or sliding. This has never been possible before where the entire drilling operation had to stop to take...

.... The distance between the two sets is fixed. It may vary during the survey, but it needs to be accurately measured and/or known at all instances. The GDA technique is used in Measurement-While-Drilling (MWD) in areas and circumstances with high magnetic interference due to a number of sources: nearly...

... accurately. Abstract This paper describes the successful use of mud-pulse Measurement While Drilling (MWD) and Rotary Steerable directional systems (RSS) in an Underbalanced Drilling (UBD) environment utilising up to 40% nitrogen. There are few documented examples of mud-pulse telemetry being...

... analysis (MSA). In-Field Referencing (IFR) Technique Abstract Safe and economical determination of wellbore trajectory in directional drilling is traditionally achieved by measurement-while-drilling (MWD) methods which implement magnetic north-seeking sensor packages. However, inaccuracies...

... to the drilling operations problem in real time. The majority of the drilling bottomhole assemblies (BHAs) consist of drive systems containing a positive displacement motor or rotary steerable system (RSS) and measurement-while-drilling (MWD) tool. The MWD tool includes the survey package that measures...

... Abstract This paper presents an investigation of true downhole dynamic conditions through improved testing methods and a new measurement-while-drilling (MWD) tool. Shock loads may cause severe damage to bottomhole assembly (BHA) components. Consequently, characterizing the shock loads...

... as designers of 175°C+ Measurement-While-Drilling (MWD) systems face new challenges in making their designs work to reliability and operating time requirements, so are they finding newly-available opportunities to help them meet those requirements. This paper summarizes a recent cross-disciplinary effort...

... in this gigantic field with over 800 wells drilled by two different operators with several hundreds more wells to follow. Almost all Bottom Hole Assemblies (BHA) run in this field include a Measurement-While-Drilling (MWD) survey tool to survey the wellbore while drilling. The MWD is a magnetic survey tool...

..., placing a real-time caliper tool above the reamer would prevent the ball from reaching the reamer. Additionally, such a configuration would prevent electrical signal communication between the LWD tool and the real-time data transmission available at the measurements-while-drilling (MWD) tool. Hence...
