Petroleum Engineering Department (PE)

Operations Support & Data Services:

Providing timely & reliable processing, integration, & interpretation of your E&P data.

PE provide the services which are designed to manage, interpret, and deliver data when and where it is needed. Also provide timely and reliable processing, integration, and interpretation of all types of E&P data, make the most of the value of the data and allowing our customers to make better-informed operational decisions.

PE interpretations provide reservoir & formation properties that are key to characterizing and understanding the reservoir  e.g., Lithology, Porosity, Permeability, Formation Thickness, Fluid Saturation, Pressure, Rock Mechanical properties, and etc. These results enable E&P companies to determine hydrocarbon reserves and reservoir performance, decide where to complete, how to stimulate, and where to drill next, as well as to devise long-term field development strategies.

PE Geoscientists and Petro Technical Engineers work and supports clients  from pre-job,  realtime acquisition to final delivery of results to confirm the data and interpretation products meet the clients needs. Since E&P data must often be processed, interpreted, and delivered quickly to support critical decisions impacting well-site operations, PE provides services on TAT (Turn Around Time) basis.

Key Services

PE is providing the SLD technology in order to support the wirline and D&M data interpretation to maximize the information from well & Filed data measurements. Different disciplines are cover in PE:

Predict drilling risks in your first well and maximize recovery from mature assets with enhanced petro-technical services for Geo-mechanics.

Evaluate the properties that help determine hydrocarbon reserves and reservoir producibility, decide where to complete and how to stimulate, pinpoint where to drill next, and devise long-term field development strategies.

Our borehole imaging services give you micro-resistivity formation images in both water-base and non-conductive mud.

By doing advanced interpretation on real time LWD and MWD data, PE is providing the most advanced well trajectory design and geo-streering services in order to improve well placement.

PE is using the SLD technology in data gathering, data processing and interpretation of borehole seismic and vertical seismic profiling (VSP) and acting as a market leader in this domain.

This service includes PSP (Production logging) Pre/Post acids, interpretation which gives efficient production contribution of each reservoir, evaluate the acid job, detect the possible water entry points and also detect any possible cross flow(s) during a shut-in survey,  zones rate.

Sampling & Interpretation which will gives:

Reservoir Pressure versus Depth, Reservoir fluid Mobility, Sampling for lab analysis, PVT, Vertical Permeability
