... mode can send data to multiple MSBs simultaneously. The MSB uses an MSP430 chip to manage reading, writing, and erasing of data. The capacity of the memory chip determines the data capacity of the MSB. Currently, the data capacity of one MSB is 1 Mbit. The diameter of the MSB circuit board is 11 mm...

... the cone (Fig. 1b). This reduces the internal diameter of the flowline around the cone and causes the differential pressure to move into the measurable range. The meter then uses the differential pressure to again produce accurate flow measurements. In addition, the meter has a second differential pressure...

... the liability of obsolete equipment. The authors write that, ultimately, BOPs will need to cut 175-grade CT strings with a 7-mm wall thickness with 103 MPa of wellbore pressure and less than 17.2 MPa hydraulic pressure. Development Process Initially, the following five options were considered: - Larger-diameter...

...-hole diameters were used. The experiment began with the lowest inlet pressure, which gradually was increased to the maximum pressure. The outlet pressure was kept constant at an ambient pressure. The flow rate increased because of the increase in differential pressure. After reaching the maximum...

... pressure. The results show that the mean slug length initially increases with the distance from the inlet but that this increase slows and the mean slug length typically reaches a value between 20 and 50 diameters at the outlet. At low flow rates, slug-length distributions tend to be extremely wide...

... is useful because most often those dealing with the problem will never know more about the damage than the inner diameter of the casing has been narrowed - ovalized is the popular term for it - and that they need to find a smaller-diameter tool to get past the obstacle. Eric Davis, the global completions...

... where the combination of oil-based-mud systems and small wellbore diameters (approximately 6 in.) at the target zones are the only way to minimize wellbore-stability problems. Data acquisition is also challenged because logging-while-drilling technologies are sometimes limited in small wellbores...

... on extruded HDPE pipe sec- tions in simulated Casabe-field-flowline conditions, a pup joint with a 3.5-in. out- side diameter with HDPE liner was eval- uated under simulated downhole high- pressure/high-temperature (HP/HT) conditions. For these tests, 20-cm sections of the HDPE-lined pup joint were immersed...

Expandable Technology Expandable technology provides operators an alternative to conventional liner hanger and packer systems that typically use slips and cone components configured on the outer diameter of a hanger body that require translation of the slips onto the cone for installation of the liner hanger...

Often the deformation is described as ovalling. If a restriction consumes much more than a tenth of an inch of the pipe’s original internal diameter...

The contact area is an annular ring on the surface of the port where neither production nor annulus pressure is acting. The width of this area changes with the valve-dome pressure, strength of port material, port size, and lap band...
