Abstract

Purpose

The purpose of this paper was to examine the attitudes of prison inmates and warders (prison staff) to rehabilitative counselling and its relationship to their prison status on one hand and their educational attainment on the other.

Design/methodology/approach

The study adopts a descriptive survey research design. In all 123 prison inmates and 110 warders were selected by stratified random sampling from Osogbo prison headquarters, as well as Ilesa and Ile-Ife prisons in southwestern Nigeria. Data were collected through a self-constructed questionnaire titled “inmate and prison staff attitude to rehabilitation counselling”. Data collected were analysed using percentages and χ2 statistics.

Findings

The results showed that the prison inmates and staff possessed positive attitude to rehabilitative counselling. No significant difference was found between the attitudes of prison inmates and staff members or on the basis of their prison statuses. However, the study found a significant relationship between the prison inmates’ attitude to rehabilitative counselling and their educational attainment.

Research limitations/implications

Statutory provision needs be made for professional rehabilitative counselling in Nigerian prisons in contrast to the religious instructions currently being allowed prisoners. Educational opportunities should be provided to ensure that the knowledge so obtained complements the rehabilitative counselling.

Originality/value

This paper fulfils an identified need to study the attitude towards rehabilitative counselling.

Abstract

Purpose

The production of natural gas from the reservoir is always associated with entrained solid particle of different sizes mainly sand particles and crystalline salts. Entrained solid transport along the gas phase has been a great concern for gas production engineer, as the detrimental consequences are often associated to a desirable high operational parameters such rate and pressure transverse in producing well.

Design/methodology/approach

A variety of models for predicting pressure transverse in flowing gas wells have been reported in the literatures. Most of the models were based on steady state fluid flow equation that did not consider time factor which results in inaccurate at early production time. Some of the early investigators overlooked the effect of the entrained solid on the pressure transverse phenomena in a gas well. Hence, there is a need for developing a more realistic model for estimating pressure transverse at all times in flowing solid-gas vertical well.

Findings

This study presents equation for pressure drop in flowing vertical well without neglecting any term in the momentum equation by the inclusion of accumulation and kinetic term. The solution of the resulting differential equation gives functional relationship between solid-gas flow rates and pressure at any point in flowing well at any given production time.

Originality/value

The results show improvement over previous studies, as the assumptions previously neglected were all considered.

Abstract

Purpose

The purpose of this study showcase a realistic model for estimating pressure drop at any production time in any location along the vertical flowing solid-gas well. Also to simulate the impact of solid particles on the pressure transient in gas well. The production of natural gas from the reservoir is always associated with entrained solid particle of different sizes, mainly sand particles and crystalline salts. Entrained solid transport along the gas phase has been a great concern for gas production engineer, as the detrimental consequences are often associated to desirable high operational parameters, such as rate and pressure transverse in producing well.

Design/methodology/approach

A variety of early models for predicting pressure transverse in gas wells were based on steady state flow equation that did not consider time factor, which results in inaccuracy at early production time. Some of the early investigators overlooked the effect of the solid on the pressure transverse phenomena in a gas well. Hence, there is a need for developing a model for estimating pressure transverse at all times in solid–gas well. This study presents an equation for pressure drop in flowing vertical well without neglecting any term in the momentum equation by the inclusion of accumulation and kinetic term.

Findings

The solution of the resulting differential equation gives functional relationship between solid–gas flow rates and pressure at any point in flowing well at any given production time. The results show improvement over previous studies, as the assumptions previously neglected were all considered.

Originality/value

A more realistic result that includes the initial unsteadiness phenomenon is obtained; hence, predicting pressure transient at any given production time has been established for both gas that flows along with solid particles and gas without particles. At the onset of production, the effect of all possible wellbore pressure losses is highly pronounced and decreased as the production time increases. The newly developed model, however, can be used at all depths. The effect of using the Sukkar and Cornell model is extremely adverse for the calculation of other parameters, such as flow rate, and carrying out economic analysis.
