Relationship of maxillary and mandibular effective base length, arch length and dental crowding in different vertical growth pattern
Authors: Satra Priyanka , Vichare Gauri , Bhosale Veera 
Published: January 2022

Objectives:
The objectives of the study were to assess, measure, and correlate the maxillary and mandibular effective base length, arch length to the amount of dental crowding in different vertical growth pattern patients.

Materials and Methods:
Sample comprising 100 pre-treatment lateral cephalograms and study models (age group – 16–25 years) was randomly selected. The sample was divided into two groups, that is, clockwise (50) and anticlockwise (50) rotation based on the measurement of the gonial angle. The gonial angle and maxillary and mandibular effective lengths were measured on pre-treatment lateral cephalograms. Dental crowding and arch length were measured on the pre-treatment dental casts. Intergroup comparisons of effective base length, arch length, and crowding were performed with unpaired t-tests. Correlations between effective base length, arch length, and dental crowding were examined by means of Pearson’s correlation coefficient (P < 0.05).

Results:
Subjects with clockwise rotation significantly had more mandibular dental crowding and significantly decreased mandibular arch length compared to the anticlockwise group. An inverse correlation was found between maxillary and mandibular effective base length, arch length, and dental crowding while a positive correlation was found between maxillary and mandibular base length and arch length in both the groups.

Conclusion:
Clockwise rotation of the mandible along with skeletal and dental factors such as decreased effective base lengths and arch length, respectively, constitutes an important factor leading to dental crowding.

Authors: Andaluz Luis David Molina , Gonzalez Josué Alejandro Cervantes , Ramírez Zita Elizabeth Salazar , Ramírez Nelly , Castellanos Luis Guillermo , Estrada Eric Misael Estrada 
Published: January 2022

Background:
Solitary bone plasmacytoma is a plasmatic cell dyscrasia; its presentation in the posterior fossa is very rare.

Case Description:
We present two cases, a 59-year-old male and a 50-year-old female, both with heterogeneous clinical presentation. One had symptoms compatible with endocranial hypertension, and the other presented with a hemispheric cerebellar syndrome and ipsilateral trigeminal neuralgia. They were both related to an intraosseous tumor of the occipital region near the torcula with large extension to the posterior fossa. The diagnosis of a plasma cell neoplasm arising from the diploe of the squamous portion of the occipital bone was confirmed with immunohistochemistry.

Conclusion:
The treatment for a cranial tumor that is suspected to be a solitary bone plasmacytoma requires a multidisciplinary team to diagnose, plan a total resection, and after surgery continue with the follow-up of the patient. Solitary bone plasmacytoma should be considered as a differential diagnosis for a tumor that produces cancellous bone widening without sclerotic borders.

Value Risk Premium and Stock Returns in Kenya: Exploring the Moderating Effect of Investor Sentiment
Authors: Mugenda Nebat Galo , Olweny Tobias , Wepukhulu Joshua M. 
Published: January 2022

Purpose:Prior literature has focused on the direct effect of firm level fundamental characteristics on stock returns while ignoring the likely effect of investor irrationality on asset pricing decisions. The purpose of this study is to investigate the role of investor sentiment in the relationship between value risk premium and stock returns in Kenya.
Design/methodology/approach:
The study utilized monthly time series data for 60 companies listed at the NSE over the recent 9 years from 2011-2019. The study employed time series regression using ARDL and VEC estimation techniques to examine whether the effect of value risk on stock returns will vary with level of investor sentiment.
Findings: Results show weak evidence for existence of value risk premium at the NSE using the main effects model. The pricing effect of value risk premium is however enhanced in the interaction model. The interaction though not significant implying that there is no moderating effect of sentiment.
Research limitations: The shorter nine-year period considered by the study could be a source of small sample bias in the estimation. Sample periods for studies in mature markets span for over decades. In this light, making comparison of the findings in this thesis with those of other related studies may not be feasible.
Originality/Value: This study is first of its kind to analyze the moderating effect of investor behavior on asset pricing for an emerging market. The paper contributes to portfolio management and asset pricing literature for emerging markets.

INVESTIGATION OF THE RISKS OF INTRODUCING PRODUCED WATER INTO FRESHWATER INJECTION SYSTEM
Authors: Usman Usman 
Published: January 2022

Mixing of waters from different sources may exacerbate the risk of formation damage and can impact on oil recovery. A case study is presented to demonstrate how to assess these risks. The study relies on laboratory-based work. Appropriate materials, methods, and procedures to assure the quality of test data and derive technically valid risks potential interpretations are discussed. The risks for potential plugging, scaling, permeability reduction, and oil recovery loss caused by introducing produced water are identified. Plugging is caused by bacterial growth and solid particles present in produced water. Bacterial growth is categorized as high. Solids Concentration is also high with its mean diameter larger than the non-damaging particle size. The CaCO3 scale is likely at reservoir temperature due to high concentration of HCO-3 in the produced water. Mixing of untreated produced water and treated freshwater caused signifi- cantly reduction in permeability. For the 25% PW and 75% FW mix, the permeability decreases by about 80% of its initial permeability. Adding 2000 ppm of biocide and fi ltered using 11 micron filter paper improved the quality of produced water. For the same mixing fraction, the permeability decreases only 47%. Analysis of pore throat size in conjunction with particle size of water samples suggests the need for using a fi lter less than 11 micron to avoid permeability decline imposed by solid particles. Waterflood experiments showed an ultimate recovery factor of 46.1% of original oil in place obtained from freshwater injection. Introducing 50% of produced water caused an oil recovery loss of 16% compared to freshwater injection alone. This lost oil recovery represents a quantitative effect of formation damage on oil production and may be valuable from the economic viewpoint.
A CASE STUDY OF FORMATION DAMAGE MITIGATION ON “X” FIELD, SUMATRA
Authors: Anggraeni Septi 
Published: January 2022

Formation damage might cause low oil well productivity, therefore it is very important to effectively handle this issue. In fact, every operation in the field-drilling, completion, workover, production and stimulation, is a potential source of formation damage. In this case study, the oil company “A” plan to dispose produced water into Formation B, J, K, D,M. Laboratory tests were performed to investigate the effect of the injection of water into the reservoir formation. The experiment was conducted by measuring water permeability as a function of fluid volume injection. In addition, XRD analysis was also performed on effluent filtrate to support the results. Prior to investigating the sensitivity of reservoir rock to the fluid injection, the samples were injected with fresh water, saline water, produced water collected from Central Injection Facility, and also Filtered CIF Water. The results indicated that all formations were sensitive to fresh water and produced water. Moreover, the use of a filter will improve the water quality. Therefore, the produced water should be treated by using a filter and increasing water salinity. The XRD analysis showed that the potential damage is mostly caused by fine migration clay, however, swelling clay is also present in the small part of formation. The test results will be used for water treatment design, so as to minimize formation damage.

Published: January 2022

A detailed combined geological and geophysical study in North Sumatra basin has shown that prospective formations for shale play containing gas sweet spots are found to be in shales from Bampo, Belumai, and Baong Formations. Bampo Formation exhibits low shale gas potential with very low to medium in organic material contents, maturity index of immature to mature, and moderate brittleness. Rocks within the formation tend to be reactive to highly reactive to water, with a moderate degree of swelling capacity. Porosity varies within 5.8 - 7.4 % with permeability ranging from 0.37 to 3.2 mD. Sweet spots in the formation found around Basilam-1 and Securai-1wells occupy about 21% of the formation. On the other hand, Belumai Formation shows moderate to good shale gas potential, with low to high organic material contents, immature to mature levels of maturity, and moderately brittle to brittle. Sweet spot areas in the formation found around the two wells are about 29% of the formation. For Baong Formation, analysis reveals moderate to good shale gas potential, with low to medium contents of organic material, immature to mature in maturity index, moderately brittle to brittle in brittleness, and tendency of being reactive to highly reactive to water but with low degree of swelling capacity. Sweet spots in the formation found around the two wells occupies are roughly 11% of the total formation volume in the area. Basin modeling leading to gas resources estimation for Baong, Belumai and Bampo Formations has led to estimated volumes of 6,379 TCF, 16,994 TCF, and 25,024 TCF, respectively, with a total amount of 48,397 TCF. The resources figures are speculative in nature and do not incorporate any certainty and efficiency factors.
Evaluation of Chemical for Sand Consolidation in Laboratory Scale
Authors: Sugihardjo Sugihardjo 
Published: January 2022

These paper contains a highlight of laboratory experiment to evaluate the work of chemical for sand consolidation to strengthen the bonding between grains of rock while do not cause permeability reduction significantly. This experiment used reservoir rock and fluids to understand the interaction between the chemical solution and the reservoir rock and fluid. Firstly, the reservoir rock and fluid were analyzed their properties. The rock has been analyzed using CT Scan to drill the best representative core plug for the experiments, using SEM to identify the pore throat and pore geometry of the rock, using XRD to determine the minerals composition which mostly quartz. While the fluids have been analyzed for the anions and cations content, viscosity and other important properties. The brine particle content and also particle size distribution of the rock have been also over lied in the graph in order to know the possibility of bridging particle in the pore throat, but the graph looks good that no problem may arise from the bridging particle. Chemical for Sand Consolidation has been used in this experiment. Sand consolidation chemical normally contain plastic resin that has a property of bonding between solid materials. It sticks on the surface of solid materials and bonding together.The core flooding experiments have been run for 4 times, 2 times using synthetic cores and the other two using native cores. The experiments used synthetic cores reduce the permeability significantly. However, after cutting both ends of the core the permeability has indicated improvement. The other 2 experiments using native cores have reduced the permeability approximately 4 times down. The last two experiments have no cutting the ends of core for further experiments, so they cannot be compared to the first two experiment. So, the experiment procedures must be improved for the next evaluation, such as during curing time the rate of injected oil may be increased to reduce the adsorption of chemical to the surface area of the pore and also to hinder the flocculation of chemical in the pore space.
