HOUSTONSaudi Aramco has issued details of its presentations at the Offshore Technology Conference earlier this month.

“Novel Repair Systems for the Remediation of Sustained Casing Pressure,” on display at the company’s booth, explained howAramco is addressing pressure build-up between cement casings in wells (casing-casing annular pressure build-up).

A team at the Aramco Research Center-Houston is working at the fundamental molecular level to develop proprietary resin repair solutions.

Another presentation highlighted the company’s work on sensor technologies. “An untethered sensor, about the size of a golf ball, can be deployed into a well, fall to the desired depth, change its buoyancy, and then return to the surface,” said Erjola Buzi, electrical engineer and a member of the Sensor Development Team at the Houston Research Center. “During this trip, the device logs sensor measurements, and these data are retrieved after the device is recovered, offering a quick way to gather well log data for enhanced reservoir modeling and recovery.”

During OTC’s Offshore Pipelines Session, Aramco presented its findings on cyclical ratcheting resistance - the slow, incremental, and upward movement of buried pipelines.

The company also contributed to a paper on the “Interaction between Proppant Packing, Reservoir Depletion, and Fluid Flow in Hydraulic Fractures.”
