WIRELINE LOGGING SERVICES – Duties of a log witness Engineer
The market of the wireline logging services is the biggest in North America; this is where the top oil field in the world operates. Wire logging services market report put to analysis variety of trends in the market and develops the most potential growth strategy.
No oil exploration or progress organization will complete a wireline formation analysis program without taking formation pressures as a minimum. A traditional exploration wireline logging will even include taking formation samples as well. Having an organization consultant or wireline log witness on-site to make sure accurate formation pressure is bought has come to be an original technique taken via most large and small exploration companies.
It is now not problematic to fully grasp the value of taking enough formation pressures to evaluate the reservoir utterly. Inadequate formation pressure test will remove some doubt as to the formation gradient and fluid sort.
Ordinarily, the wireline logging Carrier Company is shipped stress experiment aspects or pretest features as they are referred to as, the place the logging software will try and document formation stress. These Pretest facets (record in alongside-hole -depth) are all set collectively by the reservoir engineers and petrophysics in lots of cases. The pretest features are selected after processing preliminary logs generated using the in-condominium log interpretation software. Enter data into this program incorporate the wireline log data inclusive of formation resistivity, density, porosity, slowness time (Sonic) and gamma-ray.
The fact is these pretest points do not necessarily give just right stress outcome, particularly when dealing with skinny beds, and the skill and expertise of the logging engineer are needed to adjust and nice-tuned the pretest aspects. As most logging engineers do not spend very long in the area, you will be fortunate if you have an engineer which you could trust to perform the pressure survey without further guidance and input from Exploration organization.
Most oil exploration companies have an in-house trained, or they hire a log witness or consultant who goes out to the well site to supervise the wireline logging operation. This is among the most cost-saving selections an oil corporation can make to fortify knowledge assortment and control the logging operation. There is nothing as vital as having any person who represents the consumer, is aware of their goals naturally and is exclusively concerned about getting just right formation pressures. The logging engineers have some many other issues aside from the job at hand. Most folks who have dealt with logging area engineers know that it is most likely a just right notion to have a client consultant whose wireline engineer has to be in attendance for the period of a significant logging operation.
Formation stress logging jobs can take a long time to complete. Fatigue starts to impact the judgment of the logging engineer, and there were many occasions where the log corporation representative on region turns into the only person bent on taking more strain aspects to rise, define and receive good, excellent strain knowledge. When the engineer is ready to give up and move along, ordinarily the log witness along with his experience knows where to look for possible elements for excellent stress information.
In summary, the worth of a log witness or corporation representative in the area cannot be overstated in managing and getting your cash’s worth from wireline logging operations involving a taking of formation pressures and also fluid sampling. The effect is full data healing that aids higher figuring out for active subject development.
