In order to carry the testing instrument to the required position in the horizontal/ inclined oil well, the downhole robot is designed. The downhole robot has a self driving force which is produced by the electrical motor in the robot, so it can carry the testing instrument reliably. In addition, the mechanical structure is simplified compared with that of the other downhole robot. Firstly, the mechanical structure design of the robot is introduced. The robot includes three parts: driving module, centralizing module, and base. Then, the driving force required and the power for the electrical motor in the driving module are calculated when the robot runs in the oil well. The simulation result shows that the downhole robot can work reliably in the oil well.

“…Although, the E-line coiled tubing (CT) and wireline tractor tools are the most commonly used methods to deploy the logging tools in horizontal wells, there are still challenges for both oil companies and service providers, especially with extended reach horizontal wells and/or wells with open hole completion. Accordingly, an extensive joint endevor between both parties has resulted in introducing a new technique for utilizing wireline tractor technology that has a better ability to meet the logging requirements and objectives [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] . This paper reviews the successful introduction of an electro-hydraulic tractor with Logging while Tractoring (LwT) technology using the industry standard mono-conductor logging cable technology in Saudi Arabia for extended reach horizontal open hole wells.…”

Enhancement of PLT Tool Reach in Horizontal Wells Using Advanced Wireline Tractor

et al. 2010

The horizontal wells drilled during the last few years are coming to a mature state in different fields and locations. Even the existing vertical wells are being converted to horizontal for better oil sweep and productivity. This has created the requirement to evaluate the production performance of horizontal wells to determine water source for proper monitoring and/or a remedial action.The conventional conveyance methods for the horizontal production logging tool (PLT) are either coiled tubing (CT) or E-line using a tractor. These methods satisfactorily perform in conventional horizontal wells, however, operational limitations and challenges could be encountered when the horizontal section is more complicated due to extended reach, big and inconsistent washouts and high dogleg severity. These types of challenges can prevent the passage of the logging tools to the desired depth. This has an adverse effect on both data quality and accessibility to the well's total depth (TD). Accordingly, a lot of effort is being exerted by oil companies, service providers and vendors to improve the conveying performance of logging tools using wireline tractors.An electro-hydraulic tractor with wheels was introduced and deployed for the first time in the world using mono-cable logging tractor technology into several horizontal open hole wells in a Saudi Arabian field. The wells were drilled in a carbonate formation with long horizontal sections and were producing at high rates. This tool was run as an integral part with the logging tool to help cover the entire horizontal section and reach TD while logging.The logging jobs using this new technique were completed safely and successfully at flowing and shut-in conditions. At flowing condition, the logging tool was successfully conveyed to TD and measurements were made over the entire horizontal section with the help of the tractor. The well was logged at different choke settings while measurements were taken at down passes (while tractoring) and up passes. The tractor was running at a constant speed and was able to pass a long washout of around 9" in diameter. The data analysis showed very acceptable measurements. This paper will describe the case histories, challenges, planning, deployment and advantages/disadvantages of this type of tractor.
