New drilling dynamics tool eliminates need for downhole statistical down sampling

National Oilwell Varco (NOV) has introduced the BlackBox High Frequency drilling dynamics tool, which samples dynamics data at 1500 Hz and load data at 100 Hz and records all high-speed data to its 8 GB memory. Because there is no need for downhole statistical down sampling, all data can be analyzed at surface for the entire run. DC spoke with Steve Berkman, NOV Vice President of North America Dynamic Drilling Solutions, at the 2019 OTC about how the new tool functions and why it’s particularly useful in batch drilling operations. Watch the video for more information.

Electromagnetic signals bolster new look-ahead-while-drilling service

A new look-ahead-while-drilling service called IriSphere is combining directional measurements with advanced automated inversion to detect formation features ahead of the bit, by using multifrequency transmitter and multireceiver directional subs. According to Irlan Amir, Vice President of Marketing and Technology, Drilling and Measurements for Schlumberger, the technology uses electromagnetic signals that are sent from the transmitter into the formation and retrieved by receivers to enable the look-ahead sensitivity and resistivity profiles. In this video with DC from the 2019 OTC, Mr Amir also talks about high-potential applications and benefits for the technology, as well as results achieved in a recent deployment offshore Australia.

BHGE introduces low-pressure-impact drilling fluid

In challenging wells with narrow operating windows, using a fluid with low equivalent circulating density (ECD) typically only mitigates some of the risks but doesn’t reliably meet all drilling objectives. Baker Hughes, a GE company (BHGE), has launched Delta-TEQ, a drilling fluid that the company says was designed to have low pressure impact, which helps to extend narrow windows. In this video with DC on 6 May at the 2019 OTC, Brian Teutsch, Product Management Leader for BHGE, talks about the fluid’s advanced non-aqueous formulation and explains how it was used for better hole cleaning in a deviated borehole in the Gulf of Mexico.

Active Control Device drills deepwater MPD section in Black Sea

AFGlobal recently completed the first MPD section in a Black Sea well for Shell on Noble Drilling’s Noble Globetrotter II drillship. Key to this project is the Active Control Device (ACD), which uses a non-rotating device with an actively pressurized, co-molded element to seal the wellbore annulus and divert returns. This eliminates complex bearing assemblies and high-wear rotary seal components found in traditional rotating control devices (RCDs). In this video at the 2019 OTC in Houston on 6 May, Austin Johnson, Lead Development Engineer with AFGlobal, explains how the system works and its potential benefits.
