The problem of bottom hole effusion is an important reason for the reduction and even shutdown natural gas wells. Downward velocity string drainage recovery process, which can improve flow rate discharge more liquid from wellhead. However, depth timing a technical that has been difficult to solve by field engineers. To this problem, paper designs method select in case highly deviated wells appl...

Borehole instability problems are commonly encountered while drilling highly deviated and horizontal shale gas wells within the formations associated with high-dip bedding planes. An integrated rock mechanical study is described in this paper to evaluate risk of borehole area. First, a set uniaxial compressive tests carried out measure strength shales on cores different angles between load dire...

In this review we discuss the role of dendritic cells (DC) in the pathogenesis of allergic contact hypersensitivity (ACH) and atopic disorders, such as asthma and atopic eczema. In ACH patients, DC recognize the invasion of simple chemicals such as haptens, and trigger antigen-specific T cell responses leading to the characteristic histological and clinical changes such as spongiosis and papulo...

Highly Active Anti-Retroviral Treatment (HAART) has reduced death and morbidity among people with HIV. However, HAART is not always effective, can produce serious side-effects and implies uncertainty for patients. To address HAART-related uncertainty, 20 qualitative interviews were conducted with gay men with HIV in Glasgow and London. The interviewees were purposively selected to reflect diver...

The main challenge in deviated and horizontal well drilling is hole cleaning, which involves the removal of drill cuttings maintaining a clean borehole. Insufficient cleaning can lead to issues such as stuck pipe incidents, lost circulation, slow rate penetration (ROP), difficult tripping operations, poor cementing, formation damage. advancements real-time evaluation for complex wells also trou...
