LWD sonic sensor technology can complement wireline CBL evaluation to validate top of cement

Figure 3: The same waveforms in Figure 2 are presented, along with a representative waveform shown as the green trace, which was recorded in the open-hole environment from the same closest receiver to the transmitter tool arrangement.

Evaluation of cement placement is an important part of the majority of deepwater wells. Cement placement confirmation is a critical step following the cementing operation. More than one technique can be used to provide information about the top of cement (TOC) and the depth interval of a good bond between the formation and the casing. Determining the length of annular cement coverage, which is an indication of correct cement placement, is useful knowledge before drilling and/or completion operations can proceed...

Virtual, augmented reality adoption on the horizon for drilling industry

Figure 1: The hype cycle, produced by information technology consultant Gartner, is a tool used to forecast the promise of a new technologies’ adoption within the context of the industry and individual adoption for risk. The time for VR and AR to reach the “plateau of productivity,” or mainstream adoption, is estimated at five to 10 years from 2016, with VR reaching that stage before AR.

The technologies of virtual and augmented reality (VR and AR) are increasingly in the news. At the same time, many are wondering how much of this is marketing and whether projects using these cutting-edge formats are providing early adopters a return on their investments. This article will provide an overview on the current status of VR/AR as applicable to the drilling industry...

Inspection tool uses high-definition frequency to identify corrosion in up to five tubular strings

screen-shot-2017-10-16-at-10-31-43-am

Metal corrosion can cause serious well integrity issues and nonproductive time. Halliburton launched the Electromagnetic Xaminer V (EPX V), which can identify corrosion and casing defects in up to five strings, at the 2017 SPE Annual Technical Conference and Exhibition in San Antonio, Texas. In this video from the conference on 10 October, Freeman Hill, Product Manager – Well and Reservoir Surveillance, describes how the EPX V uses high-definition frequency technology to provide a through understanding of pipe defects and metal loss throughout the well. He also discusses the various deployment methods, including slick line, for the system...

Acoustic telemetry network provides real-time data during deepwater frac pack completions

screen-shot-2017-10-16-at-10-35-10-am

Most of the telemetry platforms in existence today don’t provide real-time data during completions. XACT Downhole Telemetry developed its acoustic telemetry network to provide pressure, temperature, tension, torque and bending data during completion operations. At the 2017 SPE Annual Technical Conference and Exhibition in San Antonio, Texas....
