Successful Case - East Sea Offshore Oil Field $0.00

The well log shows an offshore well drilled in east sea.

Shell provided the paper log to LOGDIGI for evaluating the well. LOGDIGI found several pay zones (oil 72.91 m3/day), which were bypassed by traditional well log analysis & interpretation.



Another successful case, which LOGDIGI helped China National Petroleum Corp. (CNPC) to evaluate an offshore well located in east sea, penetrating an igneous rock section. The interval is from 2438m to 2498m, oil saturation is greater than 50% ~ 80% as pay which produced oil 30.64 m3/day and gas 19.44 m3/day.

What Makes Our Process More Accurate

LogDigi technology completely adopts relative concepts and rebuilds a strict lithologic conductive equation. LogDigi technology is significantly improved well log analysis technology and different from current well-logging interpretation methods that use absolute concepts. Traditional technologies are all based on an approximate value in the designing of well-logging equipment, result measurements, data collection and data processing. When facing extremely complex lithology, it is necessary to design models in each area based on changes in objective conditions. Traditional technology does not adapt based on changes of objective conditions. Traditional technology is often affected by different lithological, regional, and well conditions. Traditional technology cannot accurately locate oil and gas zones with complex lithology. LogDigi technology has changed the current technology model of evaluating quantitative oil/gas formations. This technology is a breakthrough in well-logging technology, and an innovative method for the discovery of new oil and gas zones. LogDigi technology can automatically remove the influences of lithology variations in different areas and different depths. It can also compensate complex conditions, such as influences of deep intrusion of mud filtrate in drilling with saline mud. LogDigi method also evaluates the influences of oil layer flood out and automatically finds out whether or not the parameters are accordant with actual situations. This allows us to locate oil and gas zones 90% and greater. log evalution for porosity, saturation, effective thickness of reservoir beds. This plot is one of the successful samples.

90% old oil wells do not have Nuclear and Sonic logging. For many oil companies, in order to re-exame their oil fields, they have to sent down sophisticated nuclear, and acoustic tools on a wire-line for the well. It costs them a lot to do that. We re-evalute your oil fields with your existing logs. We do not need "many times costly core sample taken from the well", and "sophisticated nuclear, and acoustic tools are sent down the well on a wire-line". What we need just gamma ray (or SP),and resistivity. We can match your budget to re-evaluate your oil fields. We determine the fluid and pressure distributions throughout the reservoir, the natural energy sources available, and the methods most useful in recovering the maximum amount of oil or gas from the reservoir. We analyze, interpret, and optimize the performance of individual wells. We decides if it is economically feasible to make the investment needed to produce the well. If it is, the production engineer is given the tasks to determined how to bring this valuable fluid to the surface. We analyze data to locate drilling sites where oil and gas may have accumulated in commercial quantities.
