Methods and systems for investigating downhole conditions

A method comprising:

• (a) running a tubular into a wellbore of a formation, the tubular comprising a tubular section having an upper and a lower fluid injection port, the tubular having a thermally insulated fiber optic cable section positioned inside the tubular extending to the upper fluid injection port, and a non-insulated fiber optic cable section positioned outside of the tubular section and extending at least from the upper to the lower fluid injection port for better thermal contact with formation fluids;
• (b) restricting fluid flow through an annulus between the tubular and the wellbore, at a location between the upper and lower fluid injection ports, during the running;
• (c) flowing a fluid through the tubular and out of at least one of the fluid injection ports while running;
• and
• (d) measuring a point pressure at one or more positions along the tubular. flowing a fluid through the tubular and through the upper fluid injection port, and sensing point pressure near the upper fluid injection port;

A system comprising:

• (a) a tubular able to extend from a surface station to a region to be logged in a wellbore, the tubular comprising a main flow passage and upper and lower fluid injection ports separated by a distance of the tubular sufficient to place an annulus flow restriction device between the fluid injection ports;
• (b) the tubular having a thermally insulated fiber optic cable section positioned inside the tubular and extending from the surface to the upper fluid injection port, and a non-insulated fiber optic cable section optically connected to the insulated fiber optic cable positioned outside of the tubular section and extending at least between the upper and lower fluid injection ports for better thermal contact with formation fluids;
• and
• (c) a annulus flow restriction device positioned between the upper and lower fluid injection ports.
