Normal Digitizing Services
It is imperative that precise and accurate petrophysical data is utilized in calculating reservoir parameters. Accurate reservoir parameters aid in a better description of the reservoir, calculation of the reserves, and pursuing any reservoir simulation studies efficiently.This illustrates the importance of testing the quality of the digital data provided by service companies prior to carrying out any interpretation procedures.Most companies digitize original logs after calibrating the different curves provided for each logging run ZZ & Associates has repeatedly encountered serious scaling errors in logs, especially in older ones. Such mistakes have affected reserve calculation in some fields by a factor of more than 50%. As a result, reservoir description is affected along with any additional planning for the future.
Scanning Services
ZZ & ASSOCIATES has adopted this technique as old paper logs and maps suffer the ravages of time and use. The high resolution scanning method allows both filtering and cleaning of logs, whilst zoom facilities provide a detailed examination of every portion of the log The scanning procedure is like obtaining a very high resolution photocopy but the information is stored in electronic form. All header information and comments will be captured in the image file too. In short, the objective can be outlined as follows
Reservoir Description
Reservoir description is the most challenging technique that ZZ & ASSOCIATES has based its reputation from. We use all the available data that can be obtained from our client to better describe the reservoir. Such data includes drilling, production, geology, geophysics, petrophysics, well logging and well test analysis.We offer our client with maps which include the following:Graphical display of well locations projected for (the country of interest) Flow capacity (kh) distribution maps Average core permeability distribution True skin distribution Pressure contour maps at different times Enhanced geological model using information from Pressure Transient Analysis interpretation.Different Services and Customers
