Complete Well Integrity Solutions Provider
Why Evaluate Well Integrity?
- Early knowledge of corrosion/PI problems can help in:
- Precise identification of failure can minimize repair expense
- Remedial action can be taken before the well is seriously damaged
- Optimization of Workover Programs for maximum efficiency
- An understanding of the corrosion pattern may help in optimizing the completion design
Measuring fingers move radially along the inner casing or tubing wall, detecting any diameter change. This produces a high resolution record of the tubular geometry which can be viewed and presented as a conventional log, a cross section, or a 3-D color enhanced image.
The Magnetic Thickness Detector (MTD) is a 1-11/16 in O.D corrosion measuring instrument primarily run through tubing with the unique ability to simultaneously inspect tubing and the casings behind it. The integrity of the casing string can be evaluated with neither the requirement for costly workover rig, nor the time consuming removal of the tubing completion.
GOWell’s latest generation MTD tool is capable of evaluating quantitative thickness measurements up to three concentric pipes. The state-of-the-art instrument combines a high power transmitter, improved signal-to-noise (SNR) electronics and fully configurable acquisition. This flexible approach allows a wide range of evaluations under different conditions and conveyance systems.
We provide the best in class Noise Logging services. The ALFA tool uses very sensitive acoustic sensors to be able to measure sound produced downhole by either gas or liquid flow. Measurements are taken over a wide frequency range, enabling a very effective way of leak detection as well as detection of various anomalies and sources.
In combination with High Resolution Temperature Tool (HRTT), the string provides accurate temperature measurements along the wellbore to locate leaks, production and injection zones, flows behind pipe and to complement various other downhole studies. The string also includes MCCL for more accurate depth correlation.
The Radial Bond Log (RBL) Tool provides proven superior reliability and responsiveness even in thin cement sheath conditions. With circumferential cement bond evaluation, the RBL identifies channels, in addition to standard cement bond logging. The main application of the Radial Bond Log Tool is to evaluate hydraulic isolation between producing and non-producing zones– a key factor needed to assess the integrity of the well.
Acquire the Full Evaluation of Flowing Profile
Production Logging Services allow a full evaluation of the static and dynamic conditions of the reservoir.
Using these key production parameters, it is possible to help the reservoir engineers in well production/injection profile adjustment, well treatments, reservoir reconstruction and stimulations. It also contributes to the drilling evaluation and production operations at the well site and diagnose potential problems such as water or gas breakthrough, cross flow of thief zones and channeling.
GOWell offers a wide range of production logging solutions for all types of downhole environments. By combining advanced technology and field experience, we are able to provide you with reliable solutions customized to fit your needs.
GOWell’s series of formation resistivity measurement tools provide quality response in all environments including low to high salinity, water based muds and oil-based muds. Our resistivity suite includes DILT, DLLT, MSFL, and AILT.
For more specific results, the tools are combinable with any other Gallop tool.
GOWell’s Telemetry/Inclinometer Gamma Ray Tool (TIGR), Litho Density Logging Tool (LDLT) & Compensated Neutron Logging Tool (CNLT), are useful in determining the Formation Porosity and lithology of a well, which helps manage production schedules and contributes to the extension of the life of a well.
To provide shale volume and hydrocarbon identification, our tools can be combined with other Gallop tools.
GOWell’s sonic suite includes our High Definition Sonic Logging tool (HDSL), and one of the latest additions to the Gallop family, the X-Dipole Logging tool (XDLT). They provide petrophysical evaluation and geophysical applications.
These include Formation Porosity measurements, seismic correlation, gas detection, rock anisotropy & permeability and cement bond evaluation, providing crucial information regarding the well.
