Abstract:
During drilling, how to achieve the aim of deviation control and fast drilling effectively is a common technique issue. Though there are some anti-deviation and well straightening methods at present in drilling fields, most of them have their disadvantages, such as decreasing the weight on bit (WOB) and the rate of penetration (ROP). These drilling methods can’t achieve the aim of deviation control and fast drilling economically and effectively in high dip, fractured, fault zones, and other abnormal formations. .

Abstract:
Drilling a borehole in Nkporo area of Ohafia in Abia state without proper investigation may lead to wasting resources if water bearing formation is not achieved. This is because borehole drilling is very expensive. It is therefore necessary to carry out proper hydro-geophysical investigation in order to identify a good aquifer before borehole drilling. Electrical resistivity method has been chosen for the investigation of the water bearing formation. The use of Schlumberger array (Vertical Electrical Sounding (VES)) method of electrical resistivity was chosen based on the geology of the study

Abstract:
Summary Horizontal drilling technology has shown to improve the production and cost–effectiveness of the well by generating multiple extraction points from a single vertical well. The efficiency of hole cleaning is reduced because of the solid–cuttings accumulation in the annulus in cases of extended–reach drilling. It is difficult to study the complex flow behavior in a drilling annulus using the existing visualization techniques. In this study, experiments were carried out in the multiphase flow–loop system consisting of a simulated drilling annulus using electrical resistance tomography (ER

In 2006, the Indian National Gas Hydrate Program Expedition 01, or NGHP-01, discovered gas hydrate as fill in near-vertical fractures in unconsolidated sediments at several drilling sites on the Indian continental margins. These gas hydrate-filled fractures were identified on logging-while-drilling resistivity images. The gas hydrate-filled fracture intervals coincide with high measured resistivity at the NGHP-01 sites. High measured resistivity translates into high hydrate saturations via Archie’s equation; however, these high saturations contradict lower gas hydrate saturations determined fr

Abstract Ultrasonic drilling enables drilling in difficult-to-machine materials, including ceramics and composites, with greater accuracy and precision. The localized and controlled energy application of ultrasonic frequency minimizes the risk of material fracture, cracks, or delamination. This capability ensures that the drilled hole maintains its intended dimensions, shape, and integrity, resulting in improved hole accuracy and overall drilled hole condition. Ultrasonic drilling is an advanced machining technique that utilizes high-frequency vibrations to improve the drilling process. In thi

Drilling high-pressure high-temperature (HPHT) wells requires a special fluid formulation that is capable of controlling the high pressure and is stable under the high downhole temperature. Barite-weighted fluids are common for such purpose because of the good properties of barite, its low cost, and its availability. However, solids settlement is a major problem encountered with this type of fluids, especially at elevated downhole temperatures. This phenomenon is known as barite sag, and it is encountered in vertical and directional wells under static or dynamic conditions leading to serious w

Abstract:
Natural fractures and faults are the imprint of tectonic and structural history of the rock section. A well-extended fracture network handles fluid channeling and unexpected pressure communication. At the wellbore, electrical images are often used to identify the existence of fracture/fault. In oil-based mud (OBM), interpreting open fracture/fault is difficult, as OBM-filled open features can appear resistive. When the borehole surface is full of spirals and drill marks, or the mud is not homogeneous, ultrasonic images quickly lose sensitivity to the fracture/fault. Further inside the formatio
