Abstract The construction of the A-2 well is considered challenging because it is a horizontal offshore HPHT well in shallow water. In fact, the well had a programmed target to reach the carbonatic rocks of the Upper Jurassic Kimmerdgian age, a light oil producing reservoir of complex type and low porosity, consequently, to select the best intervals with oil presence and define the location of water–oil contact was vital to avoid unnecessary deepening saving additional costs. Being the data interpretation of the geochemical profile in the JSK zone of main importance for reservoir characterization, allowing to determine prospective intervals in a timely manner as a key task. The information from the lithological description was integrated into the geochemical profiles, where intervals of interest are related to hydrocarbon impregnations, fluorescence and visual porosity of each one of the samples.

Introduction: Syphilis is one of several diseases that can be transmitted during pregnancy and childbirth, which can lead to complications during pregnancy and in the newborn. This is especially so when the pregnant woman is not diagnosed or treated properly and in a timely manner. Methodology: Data from 262 pregnant women prospectively included, aged 18-41years, attended at the Ponta Gêa Health Centre for antenatal clinics has been analyzed from January to September of 2016. In the prospective study, a rapid treponemal and a non-treponemal test were performed. A structured questionnaire was used to collect socio demographic and clinical variables, which was developed from the literature review. Results: The prevalence of active syphilis was 11.8%; the majority of reactive pregnant women were aged 18-25years (55.4%), (61.3%) of pregnant women were treated with doses below those recommended; only a small number of the partners were treated successfully. The highest seroprevalence of syphilis was found in housewives (77%), in those who attended primary education (71.6%) in those who had a monthly income of 1000- 3000 MZN (70.3%), in those with two or more pregnancies (55.7%) and living with someone has husband and wife (63.5%). The syphilis/HIV co-infection rate was high. Conclusion: According to the results obtained in this study, urgent measures are needed to assess the problems encountered and to improve the screening approach, treatment and monitoring of syphilis during pregnancy in order to prevent the cases of congenital syphilis.
