Uncertain times for oil and gas
Angus Rodger, Wood Mackenzie, Singapore, considers how the oil and gas industry is navigating a time of hyper-uncertainty, and what it means for Asia-Pacific.

Safety in numbers
James Hardy, Wild Well Control, USA, explains how a range of detailed engineering analyses were used to design a safe drilling diverter system on a gas production platform offshore South East Asia.

A tough nut finally cracked
Toby Menard and Nigel Rowcliffe, Cudd Pressure Control, USA, and Clinton Moss and Dan Eby, Gunnar Energy Services, USA, explain how the well control benefits of coiled tubing were combined with magnetic ranging technologies to safely and accurately drill a relief well, following several unsuccessful attempts.

Running a tight connection
Yuri Kolesnikov and Mikhail Efremenko, Gazpromneft-Zapolyarye, Russia, Albert Nurgaleev and Sergey Yakunin, TMK-Premium Service, Russia, and Albert Agishev and Maxim Marchuk, TMK, Russia, examine the application of shouldered threaded connections in horizontal wells.

Unlocking tight HPHT reservoirs economically
Mohammed Munawar, NOV, USA, explains how new frac technology is opening the door to high-pressure, high-temperature (HPHT) reservoirs previously out of reach.

The importance of feasibility studies in coiled tubing drilling
Adam Miszewski, AnTech, UK, outlines how feasibility studies can help operators get the most out of technology.

The making of a smooth energy transition
Andreas Fliss, Bjørn Tore Torvestad and Elisabeth Norheim, Archer Norway, and David Stokes, Archer UK, discuss how the upcoming energy transition can maximise efficiencies in the oil and gas industry.

Drawing a line in the sand
Shuquan Xiong, Fan Li, Congda Wei and Donghong Luo, CNOOC China Ltd. Shenzhen, and Mojtaba Moradi, Tendeka, explore how well completion technologies can improve oil recovery, performance and sustainability.

Getting out of a hole
David Cook and Greg Hauze, Coretrax, USA, look at a circulating sub designed to reduce hole cleaning time and mitigate vibrations.

Staying on the dry
Shadi Aoun and Manisha Bendbhar, Sulzer Chemtech Middle East, explain how to maintain high performance in triethylene glycol contactors in order to dehydrate gas effectively during reservoir pressure depletion.

An extra lease of life
Danny Constantinis, EM&I Group, Malta, addresses the importance of keeping existing oil and gas assets going during the transition to renewables.

On the ESG path with automated water recycling
Dean Fanguy, TETRA Technologies, USA, emphasises the ESG benefits for the environment, companies, communities and workers alike that can be reaped from automated water management.

Addressing global water production
Kelsey Gonzalez, Valiant Artificial Lift Solutions, USA, outlines how an increasing demand in oil will affect global water production, and how horizontal pumping systems can be used to address this.

Subsurface injection lessons
Pavel Khudorozhkov, Oleg Sychov and Dmitry Dolganov, AKROS LLC, Russia, and Valentin Tarsky and Ruslan Klishch, Sakhalin Energy Investment Co. Ltd., Russia, consider the findings, issues and lessons learned from the joint re-injection of drill cuttings and produced water into a low permeable formation offshore Sakhalin Island, Russia.

Mastering well placement through reinforcement learning
Vidyasagar Ananthan, Beyond Limits, USA, explores how the emerging field of reinforcement learning can help to optimise well placement and field planning in the upstream industry.

Streamlining exploration
Mike Popham, STRYDE, UK, discusses how scaling down the size and weight of seismic nodes can help streamline exploration.
