Drilling Response of Impregnated Diamond Bits: Challenges and Opportunities Drilling industry has been facing challenges associated with drilling hard and abrasive formations, where low drilling performance and short bit life lead to low rate of penetrations and number of trips. The drilling efficiency can be improved by using Impregnated Diamond (ID) bit, where the performance […]

Title:  South West Hub CO2 Storage Dynamic Modelling CO2 sequestration in underground formations is currently being considered to reduce the amount of CO2 emitted into the atmosphere. Understanding of the subsurface, trapping and containment mechanisms and the chemical and physical interactions between CO2, formation water, and formation rock is necessary before sequestration can be approved. […]

Waste Water Disposal (WWD) has been experienced for decades in Oil & Gas Industry. WWD is becoming more important operational component for many logic reasons: continuous upset-free performance of Plants, expensive surface treatment, excessive produced volumes, etc. Generally speaking, the disposal system starts at the plants sewage outlets, then settling/skimming tanks, booster pumps, injection pipelines, […]

Analytical approaches have been successfully used for decades to analyse different geomechanical related problems in the oil and gas industry. These approaches are still applicable for most of those problems. However, they may not be suitable for complex environments that the industry is dealing with nowadays. The challenges to develop complex fields urge the industry […]

This talk presents a novel rock mechanics testing method for remotely monitoring, detecting and assessing mechanical weakening and possible sand production in sandstone reservoirs during water flooding or during drilling with water-based muds. Rock mechanics triaxial tests are conducted on sandstone reservoir samples subjected to realistic in situ stresses, pore pressure, and temperature. During these […]

Well depth was measured until about two decades ago using a relatively standard procedure based on wireline logs, and it was then essentially fit-for-purpose. The measurement was subject to errors but once identified, these were generally understandable and manageable by all involved.  The measurement and definition of well depth have since become less set due […]

Oil well decline curve analysis (DCA) is used to estimate remaining reserves throughout the world. DCA is an empirical method: it requires historical production data; no simulation models are needed. It is also easier to apply, since some operators may not have the resources nor data available to construct models. Sometimes the producing oil field […]
