Determine Reservoir Compartmentalization

Knowing whether reservoir fluids are in one or in more than one compartment—and the type of fluid in each compartment—affects every step in the reservoir's development from borehole placement to completion and production options.

Borehole Seismic

• seismicVISION Seismic while Drilling Service 

  With the latest Q-Borehole integrated seismic system, this LWD service delivers traditional borehole seismic measurements, real-time checkshots, and interval velocity data to reduce uncertainty ahead of the bit.

• Q-Borehole Correct information about subsurface geology close to and ahead of the bit enables identification of compartmental changes while drilling.

Borehole Imaging

Using borehole imaging logs to verify previous measurements results in a more accurate evaluation of the reservoir and the scope of compartmentalization.

• Scope Logging while Drilling Services 

  LWD data such as electromagnetic and formation-pressure measurements improve operational safety and give an unsurpassed ability to see the reservoir during drilling.

• Microimagers

• Oil-Base MicroImager

  This tool assists in differentiation of structural and stratigraphic features, such as changes in compartments, to enable better reservoir planning for deepwater developments.

• Fullbore Formation MicroImager
  Designed for water-base mud, this modeling system improves reservoir descriptions by defining important geometries and petrophysical parameters such as changes in compartments.

Wireline Formation Fluid Samplers and Pressure Testers

Downhole acquisition of representative fluid samples and accurate pressure measurements improves decisions on facility and infrastructure design. The results can have a significant impact on determining the producibility and economics of a deepwater reservoir.

• Modular Formation Dynamics Tester 

  The MDT tool acquires high-quality pressure tests and fluid samples quickly, improving the efficiency of deepwater operations.

• PressureXpress 

  The pressure and fluid contacts of a deepwater reservoir can also influence field-development decisions. PressureXpress fluid mobility and pressure measurements are made during logging for efficiency, and the time required for pressure tests is usually less than a minute.

Downhole Fluid Sampling and Analysis

Oilphase-DBR fluid sampling and analysis centers provide mercury-free services for sampling, sample management, wellsite analyses, and laboratory studies on fluid phase behavior and flow assurance.

• InSitu Family—Fluid Profiling 

  InSitu Family services scan fluid properties in different reservoir zones to describe the entire reservoir system. The technology continuously monitors the purity of the fluid entering the tool, so Fluid Profiling is performed only when contamination levels fall to specified level. Mobile fluid phases are identified and subtle variations in fluid properties give a better understanding of zonal connectivity, an essential element for deepwater facilities development.

Surface Well Testing

The fluids produced during deepwater exploration, appraisal, or development tests must be handled using surface testing equipment when permanent production facilities are not available.

• PhaseTester Multiphase Metering Services

  This surface-based portable multiphase system takes accurate and repeatable measurements for the entire well testing process, thus ensuring any changes in reservoir conditions are quickly dealt with.

• Vx Technology

  Low-footprint multiphase flowmeter technology enables flow rate measurements of oil, gas, and water without separation.

• CleanPhase

  One of the keys to accurate reservoir characterization is monitoring well performance using precise flow rate measurements. The CleanPhase well test separator helps you be certain about well performance by optimizing retention times with SmartWeir technology and measuring each phase individually with highly accurate Coriolis meters.

• Extended Well Tests

  Extended well tests are a valuable way to estimate reservoir volume and producibility; both are key elements to understanding the extent of the reservoir and its compartmentalization. In deep water this can help in planning production facilities and in overall economics.

Drillstem Testing

Whether the goal is to determine reservoir pressure, permeability, skin, or productivity, drillstem tests deliver information from multiple zones on the same test, saving rig time and allowing faster reservoir-model updates.

• Quartet System 

  The Quartet high-performance downhole reservoir testing system delivers the highest quality pressure measurements and the most representative fluid samples—all in a single run.

• SenTREE HP 

  SenTREE HP completion test tree is a proven performer, enabling extended well tests in deep water, high pressures, and extreme temperatures.

Reservoir Simulation for Planning Facilities

Understanding how fluids will flow from each compartment of a reservoir is critical to developing appropriate facilities and infrastructure for long-term deepwater developments. ECLIPSE reservoir engineering software improves knowledge of fluid and phase behavior and how phases may change under different reservoir conditions, including depth. The result is more confidence in planning-decisions.
