The Ghanaian economy is highly exposed to petroleum price fluctuations (volatility) since petroleum revenues is a major contributor to total government revenue. The resulting volatility in government revenue also has a bullwhip effect on other sectors such as the private sector, making planning difficult and complex. This study examines the effect of petroleum price volatility (PPV) on government revenue and economic growth using quarterly time series data for the period 2010 to 2020. The study adopts the autoregressive distributed lag (ARDL) for estimating the models. Three regressions are estimated to address the set objectives of the study. A pairwise correlation matrix was adopted to determine the relationship between the variables. The findings indicate petroleum price volatility has a negative effect on government revenue both in the short run and the long run. Furthermore, the findings also demonstrate petroleum revenue makes a significant positive contribution to the growth of Ghanaian economy. [Received: January 5, 2022; Accepted: June 18, 2022]

In recent years, the high impact resistance of ridged PDC cutters has made them widely used in hard heterogeneous formations. However, theoretical studies on the impact resistance of ridged PDC cutters are still lacking. In this paper, we conduct linear cutting tests and found that the cutting surface of ridged PDC cutter can prevent the accumulation and compaction of rock debris, which significantly reduces the cutting force and mechanical specific energy (MSE), thereby increasing cutting efficiency. Then, when we analysed the vibration amplitude, frequency and rate of change of the load in the simulation, we found that the rate of change of the cutting load approximate Weibull distribution. Moreover, the load vibration amplitude and load rate of change of the ridged PDC cutter are smaller than those of the planar PDC cutter, which weakens the impact effect during the cutting process. The research results of this article can help us evaluate the impact degree of PDC cutters with different shapes when cutting rocks under different conditions. To provide assistance in optimising the shape and working parameters of PDC cutters in the future, in order to reduce impact and extend the cutting life of PDC cutters.

This paper will provide a broad high-level comprehensive review of various high-density completion fluids (HDCF) for the high pressure and high temperature (HPHT) reservoir. The goal is to explain the advantages and disadvantages of various high-density completion fluids over conventional completion fluids. Existing completion fluids solutions are low to mid-density range, expansive, limited availability, corrosion issues, and not suitable for all types of reservoir formations. Solids-free high-density completion fluids differ from conventional completion fluids in several key aspects such as high density, solids-free, low viscosity, alkaline pH, less corrosive, minimum formation damage, and thermal stability. The desired requirements from a high-density completion fluid system include insignificant solids, providing rheological stability, fulfilling environmental conditions, and reducing reservoir damage. A suitable completion fluid system can provide sufficient density for well control while eliminating solid weighting materials which are potentially formation damaging.
