The combination of AAE’s Sigma 2 acoustic protocols and SBG Systems high precision Navsight Apogee Marine INS brings together two leading names in the

Understanding and Mitigating High Frequency Torsional Oscillation (HFTO)/Torsional Resonance

Here, James Crowley, Director at Rockatek Ltd, discusses how Rockatek are leading the way helping their clients overcome damaging downhole dynamics and how they are continuing their own R&D efforts to develop cutting edge technology for the future. If you are aware of the abbreviation HFTO, you are probably very aware of how seriously it must be taken for all operators of downhole drilling systems. High Frequency Torsional Oscillation – HFTO (or Torsional Resonance as it is often referred to) is not a new phenomenon, but over the last few years, many service companies and operators have started to acknowledge the presence of HFTO and are becoming increasingly aware of the extreme power dissi

New Robust, Maintenance-Free LED Floodlights From Glamox Offer High Light Output & Long Lifetime

Caisson Guide – Cleaning, Inspection and Centraliser Installation

Tool Tec were approached in 2020 by a key client to carry out the installation of new centralisers into two of their caisson guide funnels to support both a 42" and 20" diameter caisson. From previous ROV survey footage it was clear that the original secondary retro fitted centralisers had failed and were no longer providing any support. However, some of the supporting structure and locating bolts were still in place, potentially causing issues for the installation of the new centralisers. With the use of Tool Tec’s 36" Cleaning and Inspection Tool fitted with our new extended reach manipulator module, the tool was deployed down an adjacent conductor to complete an initial clean of both cais

Water Injection for Gas Gathering

To efficiently gather the gas and/or oil in a well, following primary and secondary activities it is necessary to employ enhanced recovery techniques. The preferred method is to inject produced water at pressures to stimulate flow. IGas Energy plc has selected Cat Pumps UK Ltd. to provide engineered pump/motor skid packages due to their high reliability and robust qualities. The skid packages are ATEX rated and in some instances suitable for Sour Service (H2S). With our vast product capabilities, Cat Pumps is the pump of choice for Enhanced Gas Recovery (EGR) and Enhanced Oil Recovery (EOR) applications. We offer the following pump manifold options: • Brass; • Nickel Aluminum Bronze; • 316 s

Subsea CT Scanning: Fully Understanding Flow Assurance Issues and Validating Pipeline Integrity

As subsea pipelines age over time, the challenges posed to oilfield professionals greatly increase. Pipeline integrity issues such as corrosion, pitting and metal loss defects can arise, which in turn can affect the future operational viability of the line. Similarly, deposition build up such as wax, asphaltene, sand, scale and sludge can occur within the line, potentially leading to full or partial blockages. This in turn can restrict oil production and ultimately defer revenue. In this webinar, we will discuss how subsea CT scanning can allow oilfield professional to non-intrusively inspect and diagnose a variety of pipeline integrity flaws, as well as identify and characterise a wide rang
