This week: 3D gets its teeth into new areas, Seeing 3D without glasses ...
A 2.5 per cent fall in the FTSE 100 over the course of last week was unfortunate given the fall in UK CPI inflation, to 4.2 per cent, for June along with the lower unemployment figures released on Wednesday. The AIM All Share dipped marginally too (some 1.5 per cent), and the markets yesterday faced the continuing worry over Europe’s debt crisis after a financial health check last week on 90 of Europe’s banks resulted in 8 failing a stress test on finances, whilst another 16 were in a so called ‘danger zone’ – the news lead to difficult market conditions again yesterday, with the FTSE 100 and the DAX down 1.55 per cent, whilst NASDAQ dropped 1.44 per cent. The week ahead sees an LSE trading update on Wednesday, retail sales figures and UK public sector borrowing figures being announced on Thursday and the US deadline for reaching an agreement on raising the US debt ceiling.
3D Diagnostic Imaging (LON:3DD) (3DD 2.12p/£3.62m)
3D Diagnostics, which owns the protected rights to a technology platform with a number of significant potential commercial products, has announced a number of new distribution partners in Australia, South Africa and South East Asia, which will open the Company up to a potential 60,000 new dental practitioners. 3D’s integrated package, the Caries Management Support System, comprises the CarieScan Pro for detection of tooth decay and a software package to gather data, and will be distributed in these new territories. In Australia, the distribution partner for the product is Ivoclar Vivadent Australia which has 4 sales offices (Melbourne, Sydney, Perth and Brisbane) selling to a market of 10,000 registered dentists, whilst South Africa brings a market total of 3,000 dentists through Inter-Africa Dental Ltd. South East Asia, interestingly, is to be covered by AcuMed Pte Ltd across Malaysia, Singapore, Thailand, Indonesia, Korea and the Philippines, bringing a potential 45,000 dentists to the pool. 3D is clearly on a commercialisation path, increasing the opportunities for sale and visibility on a global scale, and now has a considerable number of distribution agreements with some of the largest countries in North America, Europe, Africa and the Asia Pacific. The recent launch of RemoteView Software to supplement the functionality of the CarieScan PRO could help to add appeal and boost sales in each of these countries.
Wellhead Casing Seal Bore for Stage Wellhead Isolation Tool
This document describes a wellhead casing seal bore for a stage wellhead isolation tool installed above a well production casing at the surface and attached to the bottom of the wellhead. The device allows a stage wellhead isolation tool (stage WIT) seal mandrel to seal in the device to completely isolate and protect the wellhead surface equipment from stimulation treatment fluids and pressures. The device allows downhole tools to be conveyed through the ID of the Stage WIT seal mandrel while it is rigged up on a wellhead during multiple stage stimulation treatments that are known to the industry.
Wellhead Casing Seal Bore for Stage Wellhead Isolation Tool
This document describes a wellhead casing seal bore for a stage wellhead isolation tool installed above a well production casing at the surface and attached to the bottom of the wellhead. The device allows a stage wellhead isolation tool (stage WIT) seal mandrel to seal in the device to completely isolate and protect the wellhead surface equipment from stimulation treatment fluids and pressures. The device allows downhole tools to be conveyed through the ID of the Stage WIT seal mandrel while it is rigged up on a wellhead during multiple stage stimulation treatments that are known to the industry.
The device maintains the same practice of attaching the wellhead to the production casing as known to the industry. The device is connected to the top of the production casing at surface, hung off in the wellhead casing hanger, and the wellhead casing head installed on top of the device, see Figure 1. The device is installed at the time of well completion for the purpose of performing multiple stimulation treatments on the well.
Figure 2 shows the device. The wellhead casing seal bore for Stage WIT is an extension of the casing and must meet or exceed the casing pressure and tensile strength ratings. The device has an ID at the top end to accommodate the stage WIT seal mandrel OD. As an example, Figure 2 shows the device with 5-1/2 inch 17 lb/ft casing ID of 4.892 inches, the ID can accommodate the stage WIT seal mandrel OD. The device transitions down to an ID to match the production casing ID connected to the bottom of the device; for example 5-1/2 inch, 26 lb/ft casing, with 4.548 inch ID. The device connects to the production casing with a m...
