Let's solve this step by step:

Expression:  
\[
(-8 + 12 - 5 + 7) \times (11 - 13 - 7 - 2)
\]

### Step 1: Simplify each part inside the parentheses.

**First parentheses:**
\[
-8 + 12 - 5 + 7 = 6
\]

**Second parentheses:**
\[
11 - 13 - 7 - 2 = -11
\]

### Step 2: Multiply the results.
\[
6 \times (-11) = -66
\]

So, the value of the expression is:
\[
-66
\]
