Logging Unit

ACE-3000 Mud Logging Unit
ACE-3000 Mud Logging Unit is a new generation of intelligent mud logging unit of SCOTON, providing final solutions for mud logging engineering in oilfields.

The system integrates powerful computer network technique, accident warning technique, 30s fast FID chromatographic technique, explosion-proof data bus transmission technique, highly accurate and reliable sensor technique, analysis and evaluation technique of rock samples such as geochemical, and quantitative fluorescence, 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.

Now, ACE-3000 Mud Logging units are serving in many domestic oilfields and international markets such as Indonesia, Burma, Sudan, Madagascar and so on.

SEMWD-2000
System Description
The system is made up of downhole tools and surface equipment. The downhole tools connected in the drilling-string can measure directional parameters and GR parameters, then send them to the surface. The waves are caught by the Surface Receiver. After amplification, de-noising and digital data acquisition, the data can be recovered, displayed and recorded by the computer, the directional parameters are displayed on the driller’s monitor. 

Application Area

CWLT-A Casing Deformation Multiparameter Combination Logging Tools
Summary
During the oilfield developmentit has very important significance to know the casing damage status, study the damage mechanism as well as take correct measures of protection and repairment. Serious deformation and damage will affect normal production of oil wells. Therefore,  to accurately and efficiently detect deformation, corrosion and damage of casing will guarantee the normal production. CWLT-A casing deformation multiparameter combination logging tools can measure thickness, ID, and damage information of casing during one logging trip.

The combination tools consist of telemetry sub, multi-finger caliper series logging tools, electromagnetic inspection logging tools, electromagnetic thickness logging tools, GR & temperature & CCL logging tools. It can also be hooked up with segmented bond tools, and measure cement bond status while testing casing damage.

Multi-finger Caliper Logging Tool Series
MIC24-A/MIC40-A/MIC60-A
Multi-finger caliper logging tool series can provide accurate measurement values of casing ID. Logging data with high quality can image 3D pictures of casing ID, and statistic data such as casing/tubing corrosion, deformation, bending etc. can also be calculated.
When starting logging, caliper will be opened by motor, gently pushed against the tubing or casing inner wall under the force of spring, then subtle changes of ID will be measured. The tools also include dip and relative orientation sensors which can be used for indicating well deviation.
