Halliburton Formation Evaluation Rdt Tool 3x305q

WIRELINE AND PERFORATING SERVICES

Reservoir Description Tool (RDT™) Now, an advanced wireline formation testing system that gives you . . . • Highest quality samples • Accurate, extensive reservoir information • Plug’n Play testing versatility . . . and much more.

Dual Probe Section

Next-Generation Tool Yields Broad Sampling Value Halliburton’s new Reservoir Description Tool (RDT), incorporating the latest technology in microprocessor control, provides clean, truly representative samples of a well’s formation fluid, along with a broad range of valuable reservoir data. This is accomplished through:

Quartz Gauge Section

• Zero Shock™ PVT bottomhole sampling • Formation fluid properties monitoring • Dual probe anisotropy testing and monitoring • Pressure gradient testing • Extended pressure range sampling

Flow-Control

Through its advanced digital control system, which makes instantaneous changes in pumpout flow rates to maintain a prescribed pressure, RDT’s Zero Shock PVT sampling method eliminates pressure transients during pumping and sampling. Two closely spaced probes are standard, providing a redundant packer seal. The in-situ PVT test determines the bubble point and ideal sampling control pressure. Sample chambers are filled against hydrostatic pressure and additional pressure can be applied to maintain its single-phase integrity against thermal gradients.

RDT enables up to eight fluid and formation properties to be monitored during testing: resistivity/capacitance, viscosity, density, bubble point, compressibility, horizontal permeability, vertical permeability and anisotropy. By monitoring these properties in real time, operators can determine the optimum point at which to take the samples: a steady state condition indicates that minimum filtrate contamination has been achieved and sampling can begin.

The Dual Probe Section (DPS) is designed to detect horizontal mobility and permeability (kh) and anisotropy (kv/kh) over an extended range of operation. The DPS pressure testing flow rates are precisely controlled with the advanced digital control system, thus achieving steady state pressures very quickly and reducing the testing time required. By running two dual probe sections in tandem, the RDT can determine the pressure gradient between the probes and profile permeability and anisotropy. This further enables an extended depth of investigation and detection of permeability barriers. The RDT also provides extended range pressure sampling through the use of two flow control pumpout sections, one configured for 4,000 psi pumping pressure and the other for 8,000 psi pumping pressure. Where zones are tested over a wide range of overbalance pressures in a single trip, the two flow control pumpout sections can extend the range of sampling, thus saving rig time and providing higher-quality samples. With this feature, the RDT can obtain samples that are not possible with current generation tools.

Summary of Benefits • Reduces contamination through faster pumpout times • Ensures sample integrity through Zero Shock™ pressure control • Provides highest-quality PVT quality samples available • Reduces rig time • Provides accurate, reliable hydrocarbon/fluid typing • Delivers improved permeability estimates • Design features offer expanded testing versatility • Built-in redundancies provide high reliability assurance
