This segment consists of Halliburton drill bits and services, wireline and perforating, testing and subsea, baroid, sperry drilling, landmark software and services, and Halliburton consulting and project management.
The results of laboratory experiments with CFC114 flowing in an electrically heated, serrated-fin or perforated fin test section to measure local boiling coefficients over a wide range of vapour quality, with mass fluxes up to 45 kg/m2 s, heat fluxes up to 3500 W/m2 and pressure of 3 bar are reported.
Moreover, the paper proposes validating the approach using experimental tests with both perforating and non-perforating impact tests on nine slabs.
Under the test conditions used, wear coefficients can be determined from perforating and non-perforating tests, although perforating tests provide more consistent results.
The two sand bodies were perforated and tested; they showed production with initial rate 370 BOPD by N2 lifting with traces of water and gas production.
This paper presents the results of two perforation tests performed to investigate porosity and permeability damage in the crushed zone due to shaped-charge perforating in gas-saturated and liquid-saturated Berea sandstones.
In the experiment, bias flow into or out of orifices (inflow or outflow) is used to change the acoustic impedance of the test perforated plates subjected to grazing flow, and the acoustic impedance is measured as a function of both grazing and bias flow speeds.
To evaluate wave-induced fatigue damage in the deepwater test string, it was assumed that a service cycle contains: deployment/retrieval for 12 h, perforating for 1 h, flowback testing at 2.92 × 104 m3/h for 8 h, flowing sampling at 1.25 × 104 m3/h for 10 h, flowing test at 5.00 × 104 m3/h for 10 h and at 6.25 × 104 m3/h for 8 h, and shut-in well for 30 h.
Perforation flow tests before and after perforating were performed according to API-RP43 procedures.
In the first step presented hereafter, the test campaign has been focused on the qualification of the background environment inside the impact chamber and on the determination of the vibration levels induced by perforating and non-perforating hypervelocity projectiles on simple aluminum plates.
