OIL AND GAS STUDIES

1. Formation Damage

Formation damage occurs when wellbore fluids used during operations impairs the permeability of reservoir rocks, thereby reducing the productivity of each well. The damage may come from solids, block pores or by drilling fluids. Minimizing these factors are vital to maximizing recovery outflow. Being aware of such implications at various drilling, completion and production operations can vastly reduce formation damage and substantially improve recovery extraction.

HPO Global is renowned for identifying current formation damage and solutions, as well as pinpointing specific indicators that may lead to formation damage.

4. Field Development Plan

Field development plans give you the best resolutions for field optimization. FDPs encompass all activities and processes required to develop a field: environmental impact, geophysics, geology, reservoir and production engineering, infrastructure, well design and construction, completion design, surface facilities, and economics and risk assessment.

 

We can assist in the planning the number of wells needed to be drilled; the recovery techniques to be used to extract from the reservoir; from the type and cost of installations; separation systems for gas and fluids; and the treatment systems need to preserve the environment.

5. Petrophysical Modeling

Integration of Core and Log-Seismic Data Combined with specialized and routine petrophysical studies, our team works with the oil and gas companies to extract the incremental recovery from existing properties. Petrophysical models based on hydraulic flow units, populated with information from core property analysis and log evaluations, are developed to maximize field understanding and improve well placement and recovery.

 

Understanding complex variations in pore geometry within different lithofacies is the key to improved reservoir description and exploitation. We utilize an effective and proven method for developing a petrophysical model and the ability to integrate geological facies with engineering petrophysical units, referred to as hydraulic units, and petrofacies evaluation. Our petrophysical models are used for determining lithology, porosity, permeability and saturations.

9. Reservoir Engineering & Simulation

At HPO Global, we have the expertise in the development of grided realization of reservoir model in order to estimate Stock Tank Oil Initially in Place accurately, and engineering/simulation model by unsealing the millions of grids to as low as thousands of grid blocks. We know that although the generation of engineering models is based on specific purpose, the Reservoir model must be general.

 

The framework at the first level controls our reservoir models. Hence a gross grid is generated based on the broad features of the reservoir framework (top and bottom depth maps, fault maps, and general strata). It is then detailed by the smaller scale features like facies changes and genetic flow units in general. This brings the first level of refinement in the reservoir model. Second level refinement corresponds to the heterogeneities in each facies, and final refinement is controlled b a consistent scale parameterization.

 

Our reservoir models are linked with the data sources in an effective and practical way so that it can be sampled and audited when generating the engineering model. It can also be accessed by different disciplines for further improvements. The reservoir model generated is similar to the shared earth concepts. Formation damage is recognized as a major contributor to anomalous production and/or abnormal decline in productivity or injective in most hydrocarbon reservoirs. Many potential pay zones have been misdiagnosed as nonproductive, and payout on investment has been delayed because of formation damage.
