Embedded Data Transfer Solution for Drilling Equipment

Increases the data transfer speed from the equipment to an external computer by 300% and minimizes equipment downtime

A global oilfield products company wanted to make its drilling equipment more efficient. To do this, they needed to increase the data transfer speed from their oil rigs.

Case Highlights

Automating data extraction from NAND memory embedded in drilling equipment. The new solution transfers data via the TCP/IP stack, thus eliminating the necessity to halt the equipment for a prolonged time period.

Fast and reliable data transfer via TCP/IP
Reduces the amount of time the equipment is idle
NAND memory read/write speed optimization

Problem

A global oilfield products company wanted to make its drilling equipment more efficient. To do this, they needed to increase the data transfer speed from their oil rigs.

The data was stored in internal 4 GB NAND flash memory integrated into a drill bit and extracted during regularly scheduled 30-minute breaks used for replacing drill bits.

Solution

Efficient data transfer

The Softeq team delivered a data transfer solution based on an embedded TCP/IP stack operating as follows:

NAND flash memory subsystem initialization
NAND read/write speed optimization
Network subsystem initialization, including DHCP, to request a network address
Embedded LwIP stack optimization to increase the data transfer rate
Launching the client application that downloads the data from NAND flash memory through the TCP/IP stack

Project Outcomes

The resulting TCP/IP-based solution transfers data within a record time of 11 minutes, which is a 300% improvement over the initial speed. Additionally, the solution significantly reduces equipment downtime as there is no need for it to remain idle during data transfer.
