Wellbore Pressure Monitoring

Measurements of the annular pressure during drilling operations have many valuable applications. The tool provides accurate downhole measurement of static and dynamic pressures. Dynamic pressures include both the equivalent circulating density (ECD) and swab and surge pressures from pipe movement when making connections or tripping. Knowledge of these pressures helps to prevent damaging the formation by exceeding the fracture pressure or allowing pressures to drop too low allowing formation fluids to flow into the wellbore. The effectiveness of hole cleaning can be determined by measuring the cuttings build up in the drilling fluid. The occurrence of other drilling hazards can be identified such as shallow water flow events or the onset of annular pickoffs. The tool can also provide accurate leak-off test (LOT) and formation integrity test (FIT) data by measuring the pressure exerted on the formation, creating time savings as it is no longer necessary to circulate and condition the mud prior to the test taking place. Having accurate wellbore pressure measurements will prevent the occurrence of non-productive time events by providing an earlier warning that a problem is developing, allowing the mud system to be maintained in optimum condition to maximize ROP.

BP needed to drill a well through a difficult section of formation well known to cause tool-damaging vibration.
Summary Summary USA, California: Operator Saves an Estimated $992,000 using a Matched Drilling System Sign in required
Halliburton had previously drilled wells in the field using a standard steerable motor assembly, but now needed to deliver improved performance using a solution able to orient and steer the well at deeper depths while overcoming strong dipping tendencies and a natural walk of the bottomhole assembly (BHA).
Summary Summary Columbia: Remote Operations Center Facilitates Nimble Geosteering to Narrow Target in Heavy Oil Sands Sign in required
To reduce costs by improving drilling time, an operator drilling through complex shale and sand formations in a remote Colombian field, where the oil-water contact can reach to within 10 feet (3 meters) true vertical depth (TVD) below the top of sand, required accurate real-time information to navigate to the target zone.
Summary Summary U.K. Offshore: Operator Saves Significant Rig Time by Gathering Complete Formation Evaluation Data in Real Time Sign in required
In an offshore U.K. well, an operator needed to obtain a complete formation evaluation (FE) data set to measure reservoir and overburden characteristics in a deviated well.
Summary Summary North Sea, Norway: Operator Successfully Runs 5 ¾-inch Slim-Hole Drilling Operation with Geo-Pilot® RSS System Sign in required
In a mature field on the Norwegian Continental Shelf of the North Sea, an operator had attempted twice to drill a new extended-reach drilling (ERD) wellbore with a 2.05 measured depth (MD) to true vertical depth (TVD) ratio that resulted in the bottomhole assembly (BHA) becoming lost in hole above the reservoir.
Summary Summary World's First Extreme-High-Temperature LWD Triple-Combo Run
With extreme bottomhole static temperatures approaching 392°F (200°C), some of the wells in the Gulf of Thailand are among the hottest in the world – far beyond the reach of conventional measurement-while-drilling/logging-while-drilling(M/LWD) tools.
