Pushing The Frontier Through Wellbore Strengthening
“New and/or improved drilling fluid technologies are promising to deliver wellbore strengthening by using small concentrations of nano materials and other advanced chemicals.”
Cutting-edge Fluid Additives for the Oil and Gas Industry
“Drilling fluid is an important part of an oil and gas drilling operation – its many uses include cooling the drill bit, removing cuttings, lubricating the well bore and providing hydrostatic pressure to balance the pressure from the reservoir.”
Holding One’s Own
“A new fluid additive used to retain drilling mud could have significant cumulative benefits.”
Application of In-House Prepared Nanoparticles as Filtration Control Additive to Reduce Formation Damage
“NP1 gave higher reduction especially at low concentrations under HPHT conditions, while NP2 yielded significant reduction at high concentration under HPHT. These trends were observed to reverse under LPLT, giving a new insight on NPs performance under different pressure and temperature conditions.”
Wellbore Strengthening In Sandstones by Means of Nanoparticle-Based Drilling Fluids
“Wellbore strengthening is an approach used to increase the fracture pressure of the rock, widen the mud window and consequently enhance the well integrity and mitigate mud losses. This paper demonstrates the feasibility of wellbore strengthening in permeable formations using oil-based mud (OBM) containing in-house prepared nanoparticles (NPs) combined with graphite.”
Experimental Investigation on Wellbore Strengthening In Shales by Means of Nanoparticle-Based Drilling Fluids
“Wellbore strengthening (WS) is the mechanism of increasing the fracture pressure of the rock at depth. Applications of WS in the drilling industry enable safe drilling by preventing mud losses, drilling in narrow mud windows, accessing reserves in depleted reservoirs, and also have the potential to reduce the number of casing strings.”
