Gas Hydrate Formation Phase Boundary Behaviour of Synthetic Natural Gas System of the Keta Basin of Ghana

Gas hydrates are considered as a major threat to the oil and gas flow assurance industry. At high pressure and low temperature conditions, gas hydrates form in pipelines and production facilities leading to pipeline blockages, high removal cost, environmental hazards and loss of lives. For a successful prevention of gas hydrate formation, predicting the hydrate formation phase boundary of hydrocarbon fluid composition becomes very necessary.

Oil Well Cement Additives: A Review of the Common Types

Abstract Additives play significant role in oil and gas well cementing operations. There are varieties of cement additives that have been developed to allow the use of Portland cement in many different oil and gas well operations. In an attempt to formulate the appropriate cement slurry for any cementing job, the right additive must selected and the right quantity must be added. Additives have different functions and are broadly classified as accelerator, retarders, extenders, fluid loss agents, dispersants and many more. Each of the broad classification has different categories of additives that have been developed to perform almost the same function during cement slurry design. However, there some additives under each major type that are commonly used in cement slurry design for oil and gas well cementing operations. This paper reviews the broad classification of oil well additives giving emphasis to the commonly used additives during oil and gas well cementing operations.

Evaluating the Effects of Monovalent and Divalent Salts on the Rheological Properties of Water Based Mud

Received: January 15, 2018 Revised: May 15, 2018 Accepted: September 11, 2018 Abstract: Introduction: Drilling fluid selection plays a key role in preventing major problems encountered during drilling operations such as hole pack-off, stuck pipe and loss circulation. Mud contamination which results from the overtreatment of the mud system with additives or foreign material entering the mud system during drilling operations causes unwanted changes in the properties of the mud. This makes the mud system inefficient in performing its major roles. This research studies the effects of monovalent and divalent salts namely Potassium Chloride, Calcium Chloride, and Magnesium Chloride on the rheological properties of water-based mud system which is most vulnerable to contamination.

The Ghana Liquefied Petroleum Gas Promotion Programme: Opportunities, Challenges and the Way Forward

The pursuit for energy has evolved over the years and this has resulted in a sharp increase in demand with a corresponding increase in needs. With an ever-increasing awareness for the use of environmentally friendly fuels, the Government of Ghana initiated the Ghana LPG Promotion Programme in 1990 with the primary aim of eliminating the flaring of LPG at Tema Oil Refinery and encouraging the citizenry to switch to LPG usage due to its advantages over wood fuel. The Ghana LPG Promotion Programme has received good responses from citizens since its inception; however, there are some challenges that have to be addressed to ensure the long-term aim of the programme is accomplished and sustained. This research seeks to identify the opportunities and the challenges of LPG promotion in Ghana using secondary data. Some of the opportunities identified included job creation; reduction in the health and environmental problems associated with wood fuel and provided alternative fuel for gasoline powered vehicles. However, some of the challenges identified included lack of safety education on LPG usage, increasing cost LPG and its accessories, sporadic shortage of LPG, lack of prototype LPG stove, lack of accessibility and poor LPG transporting network. It is recommended that Government should increase LPG access to rural consumers by encouraging private investors to build refilling plants at safe locations that can easily be accessed during market days, ensure more education on best safety practices and innovations on LPG usage to reduce LPG associated hazards and also, government should institute a clear-cut policies and regulatory changes that will encourage the usage of LPG in Ghana.
