Back To The Well - "This book will raise some eyebrows and open some minds, but it is a must-read for anyone who cares about the earth's most precious resource." - Publishers Weekly
Drought. Water. Pollution. ventilation The threat to the world's fresh water supply has never been more obvious or greater, as can be witnessed by the crisis in the water supply of Cape Town at the beginning of 2018. Not only ordinary citizens, but entire cities in dozens of countries are concerned about their water and ensure, that it is accessible, accessible and safe.
Back To The Well
In this first trade paperback on the fate and future of water, Marc de Villiers addresses some of the most important questions in the world of water. Who is the water? Is the use of water a human right? Who is responsible for keeping water clean and making sure it reaches the people who need it most? Is privatization really bad?
A Look Back At The Emblems Of The Olympic
De Villiers' inspiring book provides a candid assessment of water policy and offers innovative, real-life solutions. "Returning to the well is a powerful recipe for a sustainable water future," writes Elizabeth May.
Mark de Villiers is a famous writer and journalist. He has written 15 books, including "Water: The Fate of Our Most Precious Resource," winner of the Governor General's Award for Non-Fiction and Canada's Science Writers Award. In 2010, he was appointed to the Order of Canada. Lives in Eagle Head, Nova Scotia
"This book will blow a few flags and open a few minds, but it is a must-read for anyone who cares about the earth's most precious resource." - Publishers Weekly
"De Villiers, who has compiled a daunting list of the world's water problems, offers no solutions. In fact, because there are so many different water crises, each with their own challenges, he offers a big box of solutions." - Winnipeg Free Press

"Marc de Villiers' latest book is a compelling exploration of the brink of water wars, failures and crises, complete with a powerful prescription for a sustainable water future." - Elizabeth May
"Marc de Villiers is an expert on the vast and contested landscape of water management. Returning to Guia, he transcends ideological supremacy and careless hyperbole to provide an accurate and detailed account of the state of the planet's water today. A provocative and engagingly written book. , The hard hitting truth - Chris Turne As part of the COLOSSUS M2M expandable metal-to-metal liner suspension system portfolio, it combines metal-to-metal, gas-reinforced liners with permanent high axial load, durable seal liners. Unique Metal Morphology metal-to -metal sealing and anchoring technology forms a metal cavity to create metal-to-metal solutions that perfectly match the body shape.
To reach depths of 30,000,000 feet (9,144 m) or more, operators increase the number of casing strings in well designs. Tighter annual clearances require the use of more common connections. Conventional line suspension equipment cannot match the shut-in values in these well designs, especially when the suspension must be reconnected. With a roof connection system, operators can run a conventional suspension system and connect the roof cable to the wellhead without sacrificing enclosure integrity or rating.
If the operation of a long case is complicated by the length of the wire or poor stability, the lower step can be run as a suspension and then suspended with a steel wire, a full cover provides wire integrity. This method has the additional advantage of reducing the equivalent circuit density. It also allows you to release the void in the well under control. Operating the line system in a line-suspension installation provides the operator with full ISO 14310 V0 level downhole casing integrity.

When a long casing must run in a complex well, the inability to rotate quickly and not cover can cause the casing to not reach the total depth (TD) and drag for sweep travel.
The lower part of the casing can be operated in suspension mode with a heavy tool that provides the ability to push, pull, turn and rotate. The system has no moving parts, gauge rings, elements or offsets, making it ideal when dealing with rough hole conditions. After the liner is cemented in place and the work tools are removed from the well, the cast iron spike and casing are serviced, spaced, and hung at the wellhead. The spike is then extended to the lath receiving point, creating a continuous steel-to-steel sheath wire from the ground.
This method is suitable for offshore wells where limited space makes it necessary to achieve TD every time.
Different technologies are used when the first system is applied and requires processing. These include cemented fasteners, hydraulic anchors, elastomeric and thermoplastic seals, and intermediate packings. Many of these rely on complex processes or leave the possibility of leaks in the production case.

A liner connection combined with a liner suspension system allows the liner to rotate and create an annual VO seal. The connection system has a full metal-to-metal connection, made from a hole in the bottom of the brass receiver, and is sealed from gas-tight metal to metal. This fully sealed non-elastomer solution is currently available in 9 5/8-in × 13 3/8-in [244.5-mm × 339.7-mm] roof applications and 9 5/8-, 10 3/4-, 11 3/4 -in [244.5-, 273.1-, and 298.5 mm] spacing to be installed above. This system is compatible with line equipment from other suppliers.
Operators are increasing the number of casing strings in their well designs to reach ultra-shallow depths. These are usually thick-walled vessels to accommodate the large loads seen in wells. The clearance between these boxes is low; Conventional trip suspension equipment cannot be operated with sufficient load levels to allow these lines to be operated in sections to reduce the weight of the well and remain within the operating capability of the equipment.
For deep well applications, the mooring system can be used to attach to the casing or skylight to provide the necessary load handling capabilities in the well. The system is capable of axial loads up to 2,500,000 lbf [11.1 MN] and pressures up to 10,350 psi [71.3 MPa]. Profiles required by the system can be pre-installed in multiple locations in the mainframe or enclosure, providing flexibility for future boot and reset options. A metal-to-metal gas seal provides high axial load for complete integrity throughout the life of the well.
