Survey TRIZ Cases

MRU-based angular offset detection triggers rapid emergency disconnect at the LMRP, improving shallow-water drilling safety.

Drill string rotation and vibration generate sensor signals downhole, avoiding lithium batteries while enabling real-time speed and vibration data.

A deformable shell with filler particles lets a fluid-immersed microsystem survive harsh pressure and temperature while preserving sensing and density control.

A retrievable ESP rotor keeps the stator in the well, isolating electrical parts from downhole stress to cut workovers and lost production.

Near-bit EM signals passed through an insulated drill-string gap cut measurement delay and improve borehole trajectory control in horizontal drilling.

Nested barrier-fluid chambers keep motor lubricant separate from pumped product in an ESP without diaphragms, bellows, or external pressurization.

Adhesive and protective fibre coatings enable faster well deployment while reducing damage, interference, and installation uncertainty.

Pulse-based communication lets each wellbore switch assembly self-identify and fire detonators without address assignment, cutting wiring risk and setup time.

Cathodic protection current in well metal is harvested to power downhole devices without batteries, surface cables, or hydraulic systems.

Wireless downhole signals are filtered, code-modulated, and converted into mud pulses for reliable real-time trajectory monitoring.

Nested spools deploy optical fiber and electrical conductors together in boreholes, cutting installation time, cost, and diameter constraints.

A secondary piezoelectric transducer tracks backside waves to cancel self-induced interference and improve downhole acoustic SNR.
