GT’s open hole logging services use very sensitive wireline instruments to gather accurate geophysical data of the subsurface formations. Measurements, carried out through the drilled borehole, such as resistivity, nuclear, sonic, geometry, imaging and formation sampling, deliver valuable information used to identify hydrocarbon reservoirs and assess its potential productivity. The open hole logging services are executed with the latest Halliburton and Tucker equipment capable of resisting 20,000 PSI and maximum temperature of 177°C.

Measuring the integrity of the cement bond between the rock formation and the casing is an essential part of maintaining wellbore production. GT provides a comprehensive package of cased-hole wireline logging services to evaluate the formation and completion of the well, as well as determine the state of the cement by locating internal and external defects caused by corrosion, scale and failure.

GT’s cased-hole logging services include nuclear, cement and corrosion evaluation.

The casedhole logging services are executed with the use of Halliburton, Sondex and Tucker equipment capable of resisting 20,000 PSI and maximum temperature of 177°C.

The Simphor – drill pipe assisted well logging system, is capable of performing most logging and wireline completion operations and it can be used to:

  • Move logging, completion or production tools attached to the end of the drill string in difficult, highly inclined or horizontal parts of a well
  • Control or transmit information between the downhole tools and the surface via a wet connector/electric transmission cable
  • Circulate drilling fluid in the well during running in, running out or recording
  • Because of its principle, Flow Control Simphor can perform all logging and completion operations, which are regularly done with wireline in vertical or moderated slanted wells and eliminate the risks of “kicks” through drill pipes during the logging operation procedure from “pipe in” to “pipe out”

 

THE SIMPHOR SYSTEM CAN BE USED:

  • to control the “Kicks” in high pressure wells
  • in difficult wells
  • in highly deviated wells
  • in horizontal wells
  • in hot formations
  • in cased or open hole wells

Production logging services provide essential information about reservoir conditions enabling effective management of oil and gas assets. GT engineers identify and monitor downhole flow rate and fluid composition, temperatures and pressures to define and improve the performance of producing wells. Production logging helps to understand dynamic well behavior, provide in-depth solutions and significantly reduce exploration and production costs. The production logging services are executed with the use of equipment capable of resisting 20,000 PSI and maximum temperature of 177°C.

GT offers Wireline and Tubing Conveyed Perforating (TCP) systems. TCP can be mechanical as well as hydraulic activated. GT solutions consider the relationship between gun system, wellbore, and reservoir to help clients achieve the most production from wells.

 

EXPENDABLE HOLLOW RETRIEVABLE PERFORATING SYSTEM: Expendable Hollow Retrievable Perforating Systems are designed to be run on Wireline, Tubing and Coiled Tubing operations with a high quality standard. All explosive parts are optimized for the best perforation performance. For highest flexibility, deep penetrating and big hole charges are available.

 

THROUGH TUBING GUN SYSTEMS:

STRIP GUN:

Retrievable Strip Gun with its encapsulated TTG charges is an ultra high performance semi expendable gun system for through tubing application. The gun provides a more powerful explosive load than equivalent diameter retrievable hollow carrier systems (scallop gun). The carrier strip is recovered after firing with the charge front caps in place, leaving only a small amount of steel chips from the charge cases in the well as debris.

LINK GUN:

Link Gun with its encapsulated TTG charges permits the advantage of a steel charge combined with a die cast link for debris economy performance. This fully expendable gun finds application in through tubing operations where deep penetration phased perforations and moderate costs are primary considerations. As with all expandable guns, charge debris must be planned for considering the use of this gun.

GT offers quick and effective solutions to the stuck-pipe problems, reducing lost time and drilling cost to the minimum. Depending on well parameters and conditions the right selection of equipment and methods can be made to efficiently execute pipe recovery operations. GT provides a complete range of devices including: back-off tools, tubing and casing jet cutters and severing tools for all sizes of tubing, casing, drill pipe and drill collars.

 

The list of tools operated by GT includes:

  • Tubing jet cutters
  • Segmented casing jet cutters
  • SplitShot cutters
  • Severing tools
  • String shot back-off

MUD LOGGING UNIT

GT’s Mud Logging unit is a world advanced new explosion-proof unit (Ex control box, Ex axial flow fan, safe hatch, emergency exit, flammable gas detecting unit, H2S detecting unit, fog detecting unit and pressurized detecting unit), which is applicable to onshore, offshore and desert drilling operation areas. The system integrates powerful computer network technique, 30s fast FID chromatographic technique, explosion-proof CAN Bus data transmission technique, highly accurate and reliable sensor technique, analysis and evaluation technique of rock samples and is the center of quick and comprehensive interpretation and evaluation of oil and gas on well-site. The system can discover and evaluate oil and gas reservoirs quickly, monitor drilling engineering parameters and toxic gases such as H2S and CO2, thus ensuring drilling safety, enhancing drilling efficiency and reducing operation cost.

GT provides wireline borehole seismic services to obtain high resolution data and accurate geological picture of the reservoir, enhancing and supplementing surface seismic data.

 

Velocity Surveys

Downhole travel-time measurements produce accurate time-depth relation and seismic velocity results that can be used to calibrate surface seismic and well log data. The services include:

  • Stationary source velocity survey with near-wellhead source
  • Vertical incidence velocity survey – moving source directly above downhole receiver(s) in deviated wells

 

Vertical Seismic Profiling

VSP images the subsurface near, offset from, or beneath the well to provide critical information which can be directly correlated with well logs and surface seismic sections to improve reservoir analysis.

Downhole seismic method delivers superior data quality using the properties of acoustic waves to measure the velocity of the materials through which the waves travel.

Surveys are conducted by placing one as well as three component geophones at selected depths in the borehole to obtain shear (S) and p-wave (P) profiles of the subsurface.
