Avanti's main activities are custom/contract designs, i.e. we design electronic circuits to specifications requested by our customers. Over the last 15 years we have designed mainly (but not exclusively) for companies in the oil industry.
ELECTRONIC SYSTEMS FOR OIL FIELD APPLICATIONS ARE SPECIAL IN SEVERAL RESPECTS:
- Equipment, which is to be used down-hole in an oil well (so-called 'tools'), must operate at extremely high ambient temperatures - up to (and sometimes even beyond) 175°C / 350°F.
- Surface equipment on the other hand is often operated within an environment, where highly explosive gases may be present. In many countries this requires systems to be designed and certified as Intrinsically Safe (IS).
- Both of the above points are tightly linked with low power designs. In a high temperature environment it is essential to minimise any additional heat generated within the components through power dissipation. In an explosive environment power levels must be kept low enough to prevent them from igniting explosive gases. Besides this, long-term battery operation is often a requirement too.
Avanti Elektronik has acquired special expertise in these fields. However, we are ready to diversify into other areas too. Please contact us with your requirements.
THIS IS WHAT WE CAN DO FOR YOU:
- Hardware: We are experienced in many areas of electronic circuit design, analog as well as digital, including programmable logic, micro controllers and communications. We can provide schematics as well as PCB layouts.
- Firmware: We are experienced in both Assembler and 'C' programming. If we have the choice, we prefer the 8051 family, since we have all the necessary development tools for it. Yet we have used other micro's in the past.
- Documentation: Our designs are accompanied by immaculate revision-controlled documentation in English or German - circuit description, parts lists, assembly/test instructions, user manuals etc..
HERE ARE SOME DESIGN EXAMPLES:
- Down-hole Memory Board for measuring pressure and temperature. This comes in all kinds of different varieties: Quartz or strain-gauge, with or without SRO etc.. We have designed many different versions.
- Surface Readout System (SRO). Connected to the down-hole electronics through a single, up to 30000ft long coax cable, which carries power and signals. We have designed a number of different versions including a noise immune system, which shares the cable with a downhole tractor.
- Intrinsically Safe Depth Logger. Reads the pulses of a shaft encoder and displays/stores depth location and speed of down-hole tools together with line tension. Certified EEx ib IIC T4.
- Production Logging Tool. Modular version of a multi-channel down-hole memory board, which allows to add additional sensors and actuators (trigger modules) as required.
- Ultra High Temperature (235°C) Multidrop Quartz SRO tool using Silicon on Insulator (SOI) components.

No, sorry! Confidentiality is very important to most of our customers and therefore to us. Nobody wants to give away technologies and experience built up over many years. Often even the title of a project is regarded as sensitive information.
This is something we absolutely respect, and we have no objections to signing a confidentiality agreement prior to starting on a new contract. |
