A cost-effective downhole strain sensor tool for retrofit or new installation
Problem statement Hydraulic fracturing involves fracturing of bedrock formations by pressurized liquids and is one of the key technologies used for unconventional oil production. Usually strains on the order of 10–5 to 10–6 propagate ahead of the fractures. Monitoring and characterizing the strain on wellbores can be a formidable challenge,...

RAPIDClean: fast, accurate real-time simulations for hole cleaning operations
Problem statementImproper hole cleaning is a major cause of non-productive time (NPT) in drilling. Current hole cleaning practices are mostly based on experience, rules of thumb and simplistic calculations, and do not necessarily work as expected in all scenarios. Available models do not include parameters such as fluid compressibility, pipe rotation...

Advanced sensors for RT determination of mud density and flow rate in high-pressure conditions
Problem statementLost circulation can have disastrous consequences including blowout (uncontrolled kicks) and loss of life, so close monitoring to quickly assess and control such events is essential. Market estimates indicate that over $2 billion USD is spent annually to combat and mitigate these events. Real-time measurement of mass flow is critical...

Low-cost, energy-efficient heavy oil recovery using a closed-loop well architecture
Problem statementOil production from heavy crude oil and bitumen reserves depends on enhanced thermal and chemical extraction methods like Steam Assisted Gravity Drainage (SAGD), Cyclic Steam Stimulation (CSS), and high-pressure CSS. However, these methods have several known disadvantages. SAGD and CSS consumes much higher levels of water and natural...
