Currently, PVD Logging provides the Slickline services for most Oil and Gas Companies in Vietnam. Our Slickline services particularly reduce well intervention costs and increase production. We have the right equipment with innovative technology to perform well intervention services as well as enhance remedial service work. Our personnel, who are widely experienced and well-trained with related knowledge, can implement the services anywhere and anytime, can reduce the frequency of trips into the well and restore full production with minimum non-production time.

At PVD Logging you can find all kinds of current Slickline services ranging from the primary ones such as basic completion intervention to the advanced services such as perforation, tubing cutting, packer setting... By applying advanced technology, we can provide the services with common line instead of electric line with the peak of performance.

Production Logging - Faster, high-quality production logging answers

Memory Production Services (Sondex short compact) give you advanced production logging measurements. These measurements are of the same accuracy and quality as those from the real-time configuration in situations that preclude surface readout operation. Even when logistical, operational or down hole constraints prevent use of the surface readout system, you can diagnose down hole production confidently. Rapid deployment is safe and easy with the compact size and portability. Tools and sensors can be conveyed in the borehole by coiled tubing and Slickline.

Multi Finger Tools (MIT)

The prime use for the Multi Finger Imaging Tool is to record data to enable the clients maximize production or recovery from the field, either through appropriate remedial work on a well or by providing information to optimize the field. During the course of producing, the field problems may show up, often as the wells get older. MIT information will help towards resolving these problems and planning the scheldule of maintenance to stabilize the production...

Gradient Survey

Quartz Electronic Memory Gauge gives you high accuracy and repeatability readings of temperature and pressure; they are designed to be run in critical well testing by Slickline personnel. The compact equipment and simple operation are able to minimize the training time for users. Easy handling software will allow users to quickly generate data and interpretation at operational site.

PVD Logging supplies the most advantageous solution for perforating operation with latest technology in the world, the charges called “CONNEX” of Geodynamics help the reservoir after perforation has less dirt contamination many times compared with the normal charges using popular now.

Well co-operation with reliable expert partners like Expro, Halliburton, Metrol Technology, QuaterBack Services and the Joint Venture PVD-Expro, PVD Logging has successfully provided the Well Testing Service for domestic critical oil companies such as Cuu Long JOC, Thang Long JOC, Truong Son JOC, Vietsovpetro and received high appreciation for service quality.

Our key capabilities are in:

• Drillstem test tools;
• Surface testing equipment;
• Fluid sampling both on surface and on bottom of the well, and analysis;
• Tubing conveyed perforating;
• Analysis capabilities; and
• Data acquisition system (Including surface DAQ system, downhole memory gauges, and surface readout system both wireline conveyed and acoustic wireless)

Geo-Pressure Prediction Service

PVD Logging’s Real-Time Geo-pressure Prediction team has many years of working in Basins of Cuu Long, South Con Son, Red River and other blocks in continental shelf of Vietnam and Australia.

Our practical, efficient, proactive and actionable geo-pressure expertise has received high appreciation from our clients with the solid knowledge of geo-pressure regime, geological stratigraphy, and experiences in explorative and developing of drilling Oil & Gas operation. We are always challenging with High Pressure - High Temperature (HPHT) wells, deep gas wells, long reach horizontal, and provided Real-Time Geo-pressure Prediction service which is prediction and real-time monitoring of pore pressure and well-bore stability at the well-site by using LWD, MWD, SWD and gas data.

The Real-Time Geo-pressure Prediction service is applicable in all environments including wild-cat exploration wells; deep gas wells; wells with narrow mud weight windows; wells drilled in basins with high tectonic stresses; HPHT wells; and non-vertical and extended-reach drilling (ERD) wells.

By using the Geo-pressure prediction software & modeling, the Geo-pressure service is applicable to calculate the bottom hole pore pressure for monitoring the geo-pressure’s behavior, identification and notification of any potential risks from abnormal pressure which capably arise and result in kicks, mud losses or other well control problems. Significantly abnormal pore pressure could lead to loss of entire well, together with substantial destruction of life and property.

The Geo-pressure service plays a significant role in reducing these risks.
