Xpt schlumberger tool

Our broad range of industry-leading products and services makes it possible to efficiently accomplish downhole pressure measurement and representative fluid analysis and sampling in what are challenging environments for conventional technology: low-permeability or unconsolidated formations, heavy oil , and rugose boreholes. In this podcast with Energy Connects, Tarek Rizk, MENA President for Schlumberger, discusses the major challenge and opportunities facing the industry, including the energy transition, decarbonization, and digitalization.

Ora platform speeds dual-packer setting and fluid cleanup to acquire clean samples in 90 min, NCS. High-definition photorealistic formation images from enable determining fracture heterogeneity and RQ. Ora platform enables sampling and deep transient testing to prove productivity and delineate viscous gradient. Ora platform used intelligent planning to guide focused sampling for thorough assessment of stacked sands.

We need a little more information from you before we can grant you access. PressureXpress-HT high-temperature reservoir pressure service extends the efficiency and accuracy of PressureXpress reservoir pressure while logging service to high-temperature environments.

Specifically engineered for pressure and mobility testing—whereas conventional multifunction formation tester tools also collect fluid samples—PressureXpress-HT service significantly reduces the time and risk involved with multifunction testing operations.

Compatibility with most openhole services means the you get highly accurate pressure and mobility measurements on the first logging run. And you get them quickly: Measurements are typically made in less than a minute. The innovative tool architecture of PressureXpress-HT service provides the superior thermal stability of a quartz gauge and enables extended holding time: 14 h at degF.

The dual-flask design protects the electronic components from high temperatures. The HPHT Quartzdyne gauge is in one of the flasked sections, which also isolates it from changes in borehole temperature. Because the flask eliminates the need for gauge thermal stabilization, the uncertainty that results from erratic pressure build-down behavior is avoided and pretests are completed in less time.

To measure the formation fluid and borehole temperatures, a flowline temperature sensor is positioned outside of the flask. A temperature sensor in the toolhead provides an additional borehole temperature measurement.

The dynamically controlled enhanced pretest system incorporated in PressureXpress-HT service gives you precise control of volume and drawdown rates across a wide mobility range.

A pressure limit can be set as necessary, and the pressure differential for drawdown is up to 8, psi. Related Documents.

Fast, accurate pressure and mobility measurements on the first logging run PressureXpress reservoir pressure while logging service reduces the pressure testing process to less than a minute in most cases. PressureXpress service required a fraction of the time necessary for conventional testing tools to acquire the pressure reading.

Data you can use right away And throughout the life of the reservoir Data from PressureXpress service is the basis for accurate pressure profiles and mobility measurements that you can integrate with petrophysical, seismic, and conventional log data for a more complete reservoir picture.

Minimize sticking risk The slim OD and profile of PressureXpress pressure while logging service greatly reduce the risk of sticking. The smooth profile and small OD of the PressureXpress service minimize the risk of sticking. Interpretation Compatible with most openhole services, including the Platform Express integrated wireline logging tool and its foundational measurements for formation evaluation, PressureXpress reservoir pressure while logging service specifically conducts pressure and mobility testing.

Measuring the pressure of a rock downhole can be achieved by running a logging tool picture side — source slb. Usually 3 pretests for every pressure point are required in order to check the repeatability of the measurement. The tool is run in hole with a cable and drill pipes a technique known as Tough Logging Conditions or TLC and when the interval of interest is reached the tool is activated via the wireline cable: this expands the two legs that you see on the picture and subsequently expands the pad with the piston that will penetrate the rock and allow for a pressure measurement to be taken.

The two legs allow to push the tool towards the borehole so that the black pad sits nicely on the rock. The XPT tool allows for a measurement of the permeability of the rock but also investigates if the reservoir is depleted pressure is lower than predicted or overpressured pressure is higher than the prediction. Since this tool measures how well a reservoir will flow, for me it is the most exciting measurement to take in Salym.

Each time the pressure stabilizes, screams of joy explode in the 2 square meter logging crammed with four people inside.
