The oil industry uses geomagnetic field information to aid directional drilling operations when drilling for oil and gas offshore. These operations involve continuous monitoring of the azimuth and inclination of the well path to ensure the target is reached and, for safety reasons, to avoid collisions with existing wells. Although the most accurate method of achieving this is through a gyroscop...

Monitoring the flow rate out of the well is critical for good control of the downhole pressure in drilling operations. In this feasibility study, we explore the possibility of using a Venturi flume to provide a cost-effective measurement of the flow rate, with improved accuracy compared to conventional methods. A Venturi flume has been simulated both using CFD and a simplified 1D model. By prop...

The relevance of the application hydraulic thruster technology is determined by technological limitations drilling both vertical and horizontal wells. existing experimental studies confirm effectiveness technology, but its widespread implementation hindered lack scientific foundations for operation in combination with a downhole motor bit. Our research methodology includes methods analyzing tec...

The technical focus of drilling operations is changing to oil and gas reservoirs with higher difficulty factors such as low permeability fracture. During the process, in deep complex formations are prone overflow leakage complications. Leakage problems will change performance fluid wellbore, impacting wellbore pressure, causing accidents stuck collapse. In order improve level control over risk ...

The design trajectory parameters of 3D horizontal wells in X gas field are not uniform, the construction is random, and lack standardization enough to achieve rapid drilling. Based on analysis data difficulties completed well, according different types, by standardizing drilling tool assembly well design, making full use characteristics formation law, using supporting tools control sand carryin...

In this paper we present a review of the application of two types of magnetic sensors-fluxgate magnetometers and nuclear magnetic resonance (NMR) sensors-in the oil/gas industry. These magnetic sensors play a critical role in drilling wells safely, accurately and efficiently into a target reservoir zone by providing directional data of the well and acquiring information about the surrounding ge...

[1] Single-hole hydrogeologic experiments were conducted with a drillstring packer in Integrated Ocean Drilling Program Hole 1301B, which penetrates 318 m into 3.5-Ma upper oceanic basement on the eastern flank of the Juan de Fuca Ridge. Seven constant-rate injection tests were conducted in open hole, with the packer inflated at three depths in the deepest 166 m of the basement section. The pri...

Reliable and sufficient welltest data is necessary for the evaluation of reservoir properties and well performance. Best results a r e usually obtained by monitoring downhole pressure and flow rate continuously during a transient test. However, a recurring problem for geothermal welltests has been the failure of the downhole pressure instrument in the high temperatures and hostile environments,...
