Well Log Digitization and conversion is one of the leading technologies we utilize as it comprises the data backbone in petroleum industry. By using well log data the user may be able to calculate: Shale volume (Vsh), Water saturation (Sw), Porosity (φ), Permeability (k), Elasticity (σ,Al,Sl,etc.), reflectivity coefficient(R) etc. We focus on delivering powerful access to your data, so that you can focus on your core business. We make your process cost effective by handling this section of work. Our mission is to provide top quality services to our clients using the most efficient & responsive customer oriented approach. Our cost is so competitive, no matter if you contact us for a single well or for data in bulk.

R. S. Datum replaces a digitizer tablet. Sometimes it is necessary to extract data values from graphs, e.g. in most scientific publications only plots but no data values are published. Digitization makes it easy to actually get back numbers from such a plot, this is a step-by-step process wherein first of all analog images are imported and saved with the suitable extensions. Thereafter by using the latest internationally preferred digitizing systems, it is scaled and defined under the required axes, then digitized and out put is received in ASCII format that is LIS, LAS with different versions.
Our digitizing solution provides the option of merging multiple runs of the same curve within a log into one LAS file. In addition, curves from multiple files may be appended into a single LAS report or any ASCII format. Separate LAS file for each curve in a log can be produced too.
Warped and poor image files are corrected and produced quality log images and digital data.
Our Quality Control activity goes through different stages as our expertise and log analysts use comprehensive set of tools which provide overall measure of quality score of data. It includes checks for Pixel Overlay, Spikes, Gaps and Depth Gridding for verification of LAS data overlay quickly. The LAS report summarizes your data to check for norms.
All Log Header Information is captured under our digitizing solution.
Usually All Header Information are Captured as per Customers’ directions. (Above are just examples.)
Dipmeter log were developed to resolve the “3-points define a plane” problem in a single well bore by measuring some physical property. Dipmeter and image logs have evolved from primitive beginnings to become an essential and accurate log for assessing structure and stratigraphy of reservoir rocks. Identification of fracture intensity and fracture orientation are another important use of these logs.
Types of Dipmeter:
SDIP- Structural Dip (Geodip)
SDAZ-Structural Dip Azimuth (Geodip)
DDQR- Dip Dispersion Quality Rating (SHDT) Superfluous.
Following are usually traced at Multi-Linear scale but sometimes there are Tadpoles on Linear scale too.
P1AZ (Pad 1 Azimuth)
DEVI, HDEV (Deviation)
DAZI (Borehole Azimuth)
LDIP (Local Dipmeter)
High Quality Tadpoles (Filled-dark), Low Quality (Light-blank), One Tail, Two-Tail, Arrow.
Old style Neutron Log/ Gamma-Gamma Log or Sidewall Neutron (SNP) which recorded the Gamma ray count rates in count per second (cps). These are obsolete now and there is a need to convert them into modern Density & Porosity units (g/cc, φ) to make them useful for the petrophysicist.
We make this conversion possible by using Semi-Logarithmic approach and High porosity- Low porosity method, equations, graphs and charts.
