The worker then waits for the pressure to build up to the formation pore pressure. Determine how fluid behaves in the reservoir by collecting data at reservoir conditions.
In such cases a wireline-formation testing WFT may present a viable alternative to acquire formation-fluid samples and pressure-transient data WFT-PTA commonly known as a mini-drillstem test mini-DST.
Wireline formation testing. Wireline Formation Testing and Well Deliverability 23900 by George Stewart. Over the past two decades modern tools such as MDT RCI RDT and FRT have emerged to become as one of the critical formation evaluation means in drilling projects with high costrisk and high reward environments. Make fast accurate pressure and mobility measurements in high-temperature environments.
The tool is primarily used to obtain formation pressures at chosen locations in an interval and with an accurate quartz gauge permeability estimates may be obtained. Our proprietary technologies and conveyance systems can help you to characterize the formation design an efficient completion assess productivity diagnose downhole issues and inform. A Wireline Formation Test is the test conducted by a wireline formation tester to measure the wireline formation pressure.
Modern reservoir engineering must accommodate for a complex set of heterogeneous phases contained in the well and petroleum reservoir. WFT a or mini-DST uses a probe or a straddle packer to test a selected reservoir interval. A recently introduced wireline formation-testing tool incorporates new digital-control technology that significantly improves formation fluid sampling and pressure testing.
Renowned petroleum engineer George Stewart offers in-depth information in his latest book Wireline Formation Evaluation and Well Deliverability. A primary focus of the new technology is improving the quality of reservoir fluid samples. A companion to his recent book Well Test Design Analysis this newest technical volume covers the widest range of possible issues for reservoir engineering.
Formation testing on wireline was developed in the mid to late 1950s to provide a faster and less expensive method of formation evaluation than conventional drill stem testing DST. Experience your reservoir like never before. Achieving the optimal solution to reservoir problems involves employing sophisticated simulation techniques executing complex well.
Well Testing A tool run on an electric logging cable that pushes a probe into the formation which then allows production into a small closed chamber. The wireline formation pressure measurement is acquired by inserting a probe into the borehole wall and performing a minidrawdown and buildup by withdrawing a small amount of formation fluid and then waiting for the pressure to build up to the formation pore pressure. Test taken with a wireline formation tester.
The gradient and samples obtained from formation testing are crucial in determining thickness quality and connectivity of the hydrocarbon zone. Well geometries our wireline technologies enable testing reservoirs and taking PVT samples efficiently while minimizing sticking risks during data acquisition. High-temperature reservoir pressure service.
This measurement can provide formation pressures along the borehole thereby giving a measure of pressure with depth or along a horizontal borehole. This test is carried out by inputting an instrument probe inside the borehole wall and performing a mini draw down and buildup by withdrawing a small amount of formation fluid. Formation testing and sampling tools FTs with wireline and while-drilling are widely used in explorationappraisal and reservoir development projects.
Stationary measurements of formation pressure in an open hole are made at any number of depths during a single trip into the hole. Hydrocarbon fluid identification porosity characterization and permeability are necessary input data for a strategy to determine intervals for drillstem tests and robust resource estimations. SampleView captures the necessary reservoir fluid sample required for detailed pressure volume and temperature PVT analyses.
