Background: The goal of this study was to confirm the effects of the engineering design of the vaginal progesterone implant capsule, which had a 2 cm sponge with a diameter of 5 cm, a 2 cm porous capsule with a dose of 50 mg MAP in the centre and 13 cm nylon cord for keeping the sponge in position. Methods: A full concentrate total protein 17% consumed at 0.05 kg/day/head was previously administered to as many as 30 overweight ewes with a body score of at least 3 and those who were positively identified as having ever given birth to help them improve their body score condition. It was found that T0 consisted of 10 obese female sheep that underwent a normal oestrous cycle without oestrus synchronization therapy and waited for natural oestrus, while T1 and T2 consisted of 10 sheep that received progesterone implant capsule vaginal sponges with a dose of 50 mg MPA on day 0 getting 100 IU sc PMSG folligon intervet Holland in addition. Result: On day 35, the oestrous response was 100% and the pregnancy rates were 70%, 80% and 80% in T0, T1 and T2 groups, respectively (p greater than 0.05). Progesterone levels in the groups non pregnant are 1,66±0.8; 1,23±0.78 and 1,60 ± 0.90 ng/ml (p greater than 0.05).
In Malaysia, naturally fractured basement reservoirs around the Malay basin are being explored for additional reserves. Such reservoirs are targets by new technology tools thus allowing an optimized formation evaluation program. These reservoirs are more difficult and expensive to be evaluated compared to a conventional reservoir due to its challenging environment. This paper presents the challenges and results of the formation evaluation program in one of the fractured basement reservoirs. This particular well is a highly-deviated well drilled with oil-based mud (OBM) as it was believed that the borehole wall failures and fracture damage which occurred in previous wells was due to water-based mud (WBM) system. Current image-based fracture evaluation techniques were developed for WBM systems. However, a comparatively limited fracture analysis can still be done with the Dual Oil-base MicroImager (OBMI2) in OBM. There are inherent limitations that prevent interpreters from performing a full fracture analysis beyond fracture identification, orientation and fracture density quantification. This uncertainty could be reduced by combining the borehole image results with dual packer wireline formation tester (WFT), Sonic Scanner reflection imaging and Stoneley data: -The WFT results were used to determine whether fractures within a certain zone were open or healed. Fluid identification was performed during fluid sampling. Pressure Transient Analysis (PTA) was then carried out to gain respective reservoir parameters such as permeability thickness and skin factor. -The Stoneley fracture analysis is intended to detect open fractures with significant fluid flow. The energy loss and variation in Stoneley velocity is correlatable with fracture densities derived from OBMI and help to characterize the fracture behavior. Borehole Acoustic Reflection Survey imaging also delivers high-resolution acoustic images around the well to identify sub-seismic inter beds, faults or fractures far beyond the resolution from any seismic surveys.
