Summary: Hydraulic fracturing has become a state-of-the-art stimulation technique. It has been proved over the years that significant production increase can be obtained by applying the right fracturing technique. Now, the most advanced techniques of geothermal-energy-recovery systems widely use hydraulic fracturing. The following paper presents the experimental results of the tests carried out on four different compounds using the improved "grooved-plate" method. The tests have shown a large variation of the tested-thread-compounds sealing capacity. Starting from the experimental results and the theoretical analysis of the American Petroleum Institute (API) connection, a useful chart was built to determine the real connection resistance, on the basis of its initial makeup torque. The chart offers to engineers involved in the design of a fracturing process the possibility to estimate the maximum pressure that may lead to a connection leak.

Local stress/strain concept analysis using material properties for low-cycle fatigue can accurately predict fatigue life of casing strings exposed to variable loads. Standard approaches that assume only static loads ignore the variations in temperature and pressure that affect loads on casing strings during steam injection or in geothermal wells and lead to inaccurate estimates of fatigue life. Full-scale experimental results show that our method properly accounts for these variations, reducing time and cost in fatigue life prediction. Our method can be extended to any type of fatigue in which large deformations occur.

Drill collars are special pipes used in the drilling of wells for weighting the drill bit, enabling it to drill through the rock. In the drilling process, the drill collars are exposed to an intensive wear due to friction on inner surface of casing wall. In order to evaluate the tribological behaviour of this friction couple, paper presents the drill collars parent material, reconditioned and casing pipe chemical composition, microstructures, hardness and friction tests. For friction tests were prepared samples extracted from new and reconditioned drill collars and from casing pipes and tested on a universal tribometer. Were used plane-on-disk surface friction couples and tests were conducted at two sliding speeds and three normal loads for each materials couple. Plane static partner samples were extracted from casing pipes and disks samples were extracted from new and reconditioned drill collars. Were obtained friction coefficients values and also the temperatures increasing values due to friction working tests parameters. The temperature increasing values were obtained by measuring it with an infrared thermographic camera.

The petroleum industry is essential for supplying crude oil, which is vital for fuel and chemicals and drives substantial investments in technologies, especially in regard to increasing the durability of the drill strings used in wellbore construction. This study aims to establish and to validate a hardbanding technology for reconditioning NC50 tool joints subjected to wear, thereby increasing drill pipe durability and reducing the risk of failure during drilling, which can lead to ecological pollution, human safety issues, and financial costs. The hardbanding of the tool joints was carried out using the gas metal arc welding process (GMAW) with two different wear-resistant wires, ARNCO 100XT and FLUXOFIL M58. The equipment designed for this research allowed for the application of high-quality hardbanding layers in very good condition, according to the favorable results obtained by macroscopic analyses, metallographic studies and hardness measurements. The hardbanding procedure of the tool joint drill pipe was documented in a welding procedure specification (WPS), which validates the process and is useful for operators, drilling companies and other oilfield service companies who wish to apply under the same conditions and at the same high-quality level, in a repetitive mode, the reconditioning process to minimize the risk of drill-string failures.

This paper brings forward the results of theoretical and experimental investigations performed to determine the causes that led to the failure of 20 inches threaded casing connections during the tubing of the Lupşa Sat No. 1 oil well, Romania. The failure occurred due to the breakout of the threaded casing connections assembled in the factory. In order to establish the main causes of failure, theoretical investigations were taken into consideration to highlight the influence of the thread element errors on the correct make-up casing pin–coupling (box) conditions and to the axial tensile strength of the threaded casing connection. In addition, experimental investigations were performed on the failure casing connections, consisted of measuring the dimensional characteristics of the thread elements to determine the performance and monitor the technical condition of the tubular material used in the petroleum industry.
