An apparatus and a method of substantially sealing a throughbore of a tubular with a line running therethrough. The method comprises the steps of: (a) substantially enclosing the line and sealing a portion of the throughbore around the line using an enclosing means; (b) injecting a fluid that contains solid particles in the region of the line; and (c) substantially sealing a remaining portion of the throughbore using the solid particles such that the sealed throughbore is capable of withstanding a pressure differential. The method can include settling out the solid particles from the fluid in response to a drop in pressure of the fluid during step (b). The method can include injecting a first fluid in the region of the line prior to step (b). The first fluid can be a heavy hydrocarbon such as a grease and the fluid containing solid particles can be a drilling fluid.
