TubingConveyed Perforating | TCP Completions | Schlumberger
Tubingconveyed perforating (TCP) completion techniques enable perforating very long intervals in one run—some TCP strings have exceeded 8,000 ft [2,440 m] in length—and in highly deviated and horizontal wells, TCP is the only means of accessing the perforating depth.

The comparison of log responses between vertical and deviated wells was helpful for quality control, and in the well log modelling phase to assess the correct record of petrophysical properties for the input logs and the model ling results. Log measurements were updated and a resulting improvement in petrophysical answers was observed.

Lithology and rock type determination
· Lithology and rock type determination. The identifiion of a bed's lithology is fundamental to all reservoir characterization because the physical and chemical properties of the rock that holds hydrocarbons and/or water affect the response of every tool used to measure formation properties. Understanding reservoir lithology is the ...

Both sand and clay deposits (and sandstone and mudstone) are quite porous (30% to 50% for sand and 40% to 70% for silt and clay), but while sand can be quite permeable, clay and mudstone are not. The surface of most silie mineral grains has a slight negative charge due to .

Gas Lift
Gas lift installations manage abrasive materials, such as sand, and can be used in lowproductivity, highgas/oil ratiowells or deviated wellbores. With our gas lift products, slicklineretrievable gas lift valves can be pulled and replaced without disturbing tubing if designs or system performance must be changed.

Anisotropy correction for deviatedwell sonic logs ...
· A procedure was created to estimate the anisotropycorrected vertical sonic logs from sonic data recorded in a deviated well. The inputs are well deviation, Pwave sonic log, volume of shale or gamma ray data, and anisotropy parameters for rock with 100% shale volume.

Faults: structural geology
· Faults: structural geology. In structurally simple fields, the main control on production behavior is the distribution of lithofacies. In structurally complex fields, faults and fractures provide major elements influencing production performance.

Gravel placement techniques
· As the well deviation exceeds 60°, a gravel dune forms initially at the top of the completion interval and is propagated sequentially downwards from the top to the bottom of the completion interval. This occurs because the angle of repose has been exceeded, and gravity becomes a more dominant force that causes a gravel dune to form in the completion interval.
