2). Production Allocation

Reservoir Geochemistry for Development and Production Optimization.

Spend Less, Produce More with GeoMark

What Is Production Allocation?

When developing an asset efficiently and effectively, many questions can be answered using Production Allocation. During the development phase, routine geochemical sampling and analyses provide insights into whether the frac energy is appropriate concerning the amount of fluid accessed from day 0 to the present. These insights enable reactive development (well stacking and spacing) and production decisions (choke management, shut-in, pressure management) to optimize individual well or pad performance while minimizing hydrocarbon stranding.

Contributions: The identified collection of distinct source components of a fluid reaching a wellbore per formation, subzone, or geologic regime as defined by geochemical variance. We typically refer to single oil assessment as “Characterization.”

Allocation: The quantified contributions of discrete fluid sources can be allocated for individual fluid samples or integrated with total fluid production volumes to understand the total amount of fluid from each individual source component.

​What Questions Can We Answer?​

• ​Is production isolated to a single target?
• ​​How does the Drained Rock Volume (DRV) change over time?
• ​​Geochemistry can indicate or challenge fluid communication between wells, quantify communication between targets zones, and detect the impacts of offset production or operations.
• ​Are we leaving hydrocarbon behind?
• Is our development plan efficient and effective?
• What is your value of knowing the precise stratigraphic contribution of oil, water, or gas through time?
• Can we extract more value from our hydrocarbon product?

The GeoMark Difference

With over 30 years of experience, GeoMark offers more than just data. Backed by the industry’s largest geochemistry, gas, and PVT database (RFDbase), we provide data enriched with enhanced statistical analysis, expert geochemical knowledge, and regional geochemistry insights.

At GeoMark, we focus on the entire fluid system. We understand the importance of incorporating oil, gas, and water in our interpretations of well-to-well communication and stranded reserves. Our extensive toolbox and flexible approach allow us to tailor our analytical programs to the specific fluid system type (e.g., high maturity) and the unique questions our customers need answered.

​We believe in transparency and reproducibility. Unlike black box workflows, our data interpretation is clear, repeatable, and explainable, empowering our customers to replicate and enhance their interpretations with their own data.

​As a geochemistry company, we deliver comprehensive datasets that can be used for Time-Lapse Geochemistry & Production Allocation interpretations and to address petroleum systems questions such as hydrocarbon sources and migration. Why spend more on additional analyses?

How Effective are your Completions?

​​The image illustrates the advantages of examining the current state of a frac by visualizing the extent of the drainage heights once the wells have leveled out. This example schematic shows several "zones" under development, indicating where the fluid is coming from and whether more wells are needed to maximize production. Stimulated Rock Volume (SRV) methods often overlook the effects of unpropped "wet-frac" zones (A) and stranded well-propped fracs due to rapid fracture healing (B). In contrast, geochemical measurements directly assess the well-propped drainage zone (C), and comparing these measurements with baselines such as core, SWC, cuttings, or produced fluids can inform drainage heights.

​This schematic also demonstrates the impact of monitoring SRV versus Drained Rock Volume (DRV) over time, providing a clearer picture of subsurface well interactions and answering questions like "Has well interaction changed over time?" and "Are new fracs needed to maximize production?"

This schematic below demonstrates the impact of monitoring SRV vs. DRV overtime as it can paint a clearer picture of what is happening with wells beneath the surface, and answering questions such as "Has well interaction changed overtime?" and "Are new fracs needed to maximize production?"

​Contribution and Allocation​

• New well oil production can be allocated based on legacy produced fluids, cuttings or core rock extracts, or a combination. ​
• Allocations based on produced fluid baselines can be robust for formation or group contributions- allocation can be assigned mathematically or estimated geometrically. ​
• Allocations based on rock extracts can be more precise for higher resolution statistical allocation assignments.

Visualize Your Well's Performance

Through routine geochemical sampling and analysis, it becomes straightforward to monitor the drained rock volume and allocate production volumes throughout each well's life. GeoMark’s Production Allocation customizable dashboard offers operators the tools needed to effectively assess each well's performance in relation to the formations it is draining. This information also provides insights into potential well communication.

Another useful application is the allocation of produced fluids for each well. By allocating total fluid production to specific formations, operators gain valuable insights for potential refrac or infill well developments. Here are some key noted on fluid contribution and allocation:

• New well oil production can be allocated based on legacy produced fluids, cuttings or core rock extracts, or a combination.​

• Allocations based on produced fluid baselines can be robust for formation or group contributions- allocation can be assigned mathematically or estimated geometrically.

• Allocations based on rock extracts can be more precise for higher resolution statistical allocation assignments.

• Well Interactions: Evaluate how parent-child relationships are affecting PVT behavior
• Reservoir Continuity & Communication: Pressure assessment to identify reservoir communication
• Production Management: Fluid property assessment for choke management and production infrastructure optimization

The GeoMark Advantage

Our specialists combine engineering and geochemical analyses to effectively expand our understanding of reservoir fluids. 
With the integration of PVT and Geochemistry, we can evaluate reservoir continuity between wells. Oils in compartmentalized 
reservoirs usually differ in molecular composition caused by biodegradation, multiple charge history etc., and can explain 
the differences in fluid properties. The variations in composition can be identified using high resolution whole crude Gas 
Chromatography (GC) which separates the many molecular components in petroleum. The resulting “fingerprints” from each 
zone are compared visually and with more complex multivariate statistical techniques to determine the similarities and 
differences between samples.

Mud Gas Isotopes

GEOCHEMICAL CHARACTERIZATION 

GeoMark Research’s established Mud Gas Isotope laboratory has been serving the industry for over 15 years, providing timely and trusted gas analysis data from exploration and production wells around the world. Our data provides insights to the following:

• Gas Compositions: Cost effective screening technique to quickly identify hydrocarbon bearing zones 
• Gas Classification (Biogenic vs. Thermogenic): Helps determine the source of gas encountered within a well 
• Maturity and Mixing: Evaluates delivery of gas source maturity and relative mixing between thermogenic and bacterial (insights to migration)
• Wetness: Identifies dry gas, condensate, or oil throughout the well
• Connectivity: Assesses if reservoirs are connected or sourced from the same source 
• Helium: Exploration of alternative natural resources

The figures below present a selection of data outputs and interpretations that can be made from Mud Gas Isotope Analysis. Stable gas isotopic data (methane, ethane, propane and higher molecules) have traditionally been used as geochemical source and maturity markers and to indicate the relative concentrations of biogenic and thermogenic components in reservoir fluids. Collected over multiple wells, this data can be used to evaluate continuity between different zones in single and multiple wells; connected reservoirs should have similar isotopic values.

Data in action

Oil Family Map

This type of map represents the selected oils’ family definition, which is described more fully in a detailed, written report. In summary, these families are defined by Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA). The purpose of these unsupervised machine learning techniques is to best explain the variability of the geochemical data and understand which samples are most similar (or different) from each other and why.
